An AI sales assistant that fills the CRM so the rep does not have to
Sybill is an AI assistant for B2B sales teams that records calls with either a bot or an invisible recorder, produces magic summaries and follow-up emails in the rep's own voice, autofills CRM fields from what was said, and maintains a deal workspace with cross-conversation context that can be queried through Ask Sybill in the browser, in Slack, or from Claude via MCP; it is sold self-serve with a free tier, Pro at $30 per user per month, and Business at $90.
Overview
Sybill was founded in 2020 by Gorish Aggarwal, Nishit Asnani, Soumyarka Mondal, and Mehak Aggarwal, and it is headquartered in Mountain View. Its original claim to attention was behavioral analysis: reading the buyer's engagement and emotional signals on video calls rather than just transcribing words. That framing has receded as the product matured, and today Sybill positions itself around three things it calls context, judgment, and execution, which in plain terms means remembering everything across a deal, telling you what is actually going wrong with it, and doing the admin work that follows a call.
The strategic bet is that reps do not want a manager's dashboard, they want their evenings back. Sybill's centre of gravity is the post-call workflow: a summary that matches how you write, a follow-up email drafted from prior winning deals, CRM fields filled in without opening Salesforce, and a deal workspace that assembles calls, emails, and CRM data into one view. The coaching and competitive intelligence exist, but they are downstream of that rep-facing loop rather than the reason to buy.
Pricing is more interesting than most of the category because there is a genuinely usable free tier: unlimited recordings and transcripts, an invisible recorder, Ask Sybill across calls and email, and 20 AI meeting summaries a month. Pro at $30 per user per month removes the summary cap and unlocks unlimited storage and CRM push. Business at $90 is where the real machinery lives, including CRM autofill on 10 fields, full CRM context in Ask Sybill, the deal workspace, two-way Slack, and API plus MCP access. Enterprise adds unlimited autofill and SSO.
That $90 Business number is the pivot point of any Sybill evaluation. It is expensive next to Grain, Rafiki, or a base Avoma tier, and it is cheap next to Gong. It also comes with a weekly credit meter: summaries, briefs, follow-ups, and autofill are free of credits, while Ask Sybill threads, deeper analysis, deck and dashboard generation, and API calls consume them. Free gets 500 credits a week, Pro 2,500, Business 5,000, Enterprise unlimited. Model your actual query volume before assuming the meter is theoretical.
Best for
Individual account executives and small B2B sales teams drowning in post-call admin, especially those on Salesforce or HubSpot who want CRM fields filled automatically and deal context assembled without maintaining it by hand, and teams that want AI deal context readable from Claude or Slack rather than from another dashboard.
Not the right fit for
- Managers whose primary need is structured scorecards and rubric-based call scoring across a team; Sybill's coaching is deal and rep insight rather than a weighted scorecard engine of the Avoma or Demodesk kind.
- Budget-constrained teams that need CRM write-back, because autofill and full CRM context sit on the $90 Business tier and nothing below it does the thing most people buy Sybill for.
- High-volume outbound SDR teams running hundreds of dials a day; Sybill is built around considered B2B deal cycles, not cold-call throughput.
- Buyers who dislike consumption meters; the weekly credit allocation on Ask Sybill, analysis, and API calls is a variable you have to model rather than a flat subscription.
- Organizations with strict EU data residency requirements, since Sybill is a US-hosted vendor with no advertised regional hosting option.
How it works
- 1
Sybill captures calls two ways: a bot that joins Zoom, Google Meet, or Microsoft Teams, or an invisible recorder that captures without adding a visible participant. Dialer calls and email are pulled in as additional context sources, so the deal record is not just the video meetings.
- 2
After the call, Sybill writes a magic summary and a follow-up email in the rep's own voice, drawing on how similar deals were handled previously rather than producing a generic recap. Summaries, briefs, follow-ups, and CRM autofill do not consume credits, which is a deliberate design choice: the daily workflow is unmetered and the exploratory AI is metered.
- 3
On the Business tier, CRM autofill writes structured values into 10 configured fields on the opportunity record, and Ask Sybill gains full CRM context, so a question like why a specific deal is stalling is answered from calls, emails, Slack, and CRM data together rather than from the transcript alone. The deal workspace assembles that context into a working view per opportunity.
- 4
Access is deliberately spread across surfaces. Sybill runs in the browser, in Slack with two-way interaction, on mobile, through a public API, and through an MCP connector so Claude can query deal context directly. That MCP path is the difference between a tool you visit and a layer your other tools read from.
Feature breakdown
28 features in 5 modulesCapture
Two recording modes plus non-call context sources.- Invisible recorder
- Captures the call without a visible bot in the participant list, which is available even on the free tier and is the mode to use when a prospect would balk at a named notetaker.
- Bot-based recording
- A notetaker can join Zoom, Google Meet, and Microsoft Teams when you want the recording to be visibly disclosed and want video captured.
- Unlimited recordings and transcripts
- Included from the free tier, which is unusual; the free-tier constraint is on AI summaries and storage window, not on capture.
- Dialer and email context
- Sybill pulls dialer calls and email threads into the deal record, so context is not limited to what happened on video meetings.
- 100-plus language support
- Transcription and analysis across a broad language set for teams selling into multiple regions.
Post-call execution
The rep-facing loop that is the actual product.- Magic summaries
- Structured call summaries generated automatically; capped at 20 a month on Free and unlimited on Pro and above.
- AI follow-up emails in your voice
- Drafts the follow-up in the rep's own writing style, drawing on how comparable deals were handled, rather than producing an obviously machine-written recap.
- Customizable summaries and briefs
- Pro adds control over the shape of the output so a discovery call and a renewal produce different artefacts.
- Meeting prep briefs
- Pre-call context assembled from prior conversations, emails, and CRM data so the rep walks in knowing where the deal stands.
- Automated prompts
- Standing instructions that run against every call, available from the free tier, so a team can enforce a consistent output without manual effort.
- Collateral generation
- Business-tier users can generate decks and dashboards from deal content; this consumes credits rather than being unmetered.
CRM and deal intelligence
The $90 tier, and the reason most buyers are here.- CRM autofill on 10 fields
- Business writes structured values into 10 configured opportunity fields from call content. Enterprise removes the 10-field cap entirely.
- CRM push
- Pro can push summaries and notes into the CRM record even without field-level autofill, which covers basic activity logging.
- Deal workspace
- A per-opportunity view assembling calls, emails, Slack, and CRM data, so deal review does not require reconstructing history from four tabs.
- Deal summaries and risk judgment
- Answers questions about deal risk, next steps, and pipeline health based on what has actually won and lost at your company rather than on generic heuristics.
- Ask Sybill with full CRM context
- On Business, the assistant reasons across deals, calls, emails, Slack, and CRM together. On Free and Pro it is limited to calls and email, which is a meaningful capability gap.
- Competitive intelligence
- Tracks how competitors come up across conversations and what happens to deals where they appear.
- Rep performance insight
- Coaching views on rep behaviour and deal handling, positioned as judgment about what wins rather than as a scorecard rubric.
Surfaces and developer access
Sybill deliberately does not live in one dashboard.- Two-way Slack integration
- Business adds Slack channels you can interact with rather than only receive notifications in, so the assistant works where the deal chatter happens.
- MCP connector
- Claude and other MCP clients can query deal context directly, which turns Sybill into a data source for whatever assistant a rep already uses.
- Public API
- Available on Business and above, metered against the weekly credit allocation.
- Mobile app
- Access to summaries, briefs, and deal context away from the desk, including capture of in-person conversations.
- Custom email templates
- Business allows templated follow-ups so the AI output conforms to the team's messaging rather than to its own instincts.
Plans, credits, and security
The meter and the compliance posture.- Weekly credit allocation
- 500 credits a week on Free, 2,500 on Pro, 5,000 on Business, unlimited on Enterprise. Summaries, briefs, follow-ups, and autofill are unmetered; Ask Sybill threads, analysis, collateral generation, and API calls consume credits.
- Storage window by tier
- Free retains data on a limited window (three months) while Pro and above provide unlimited data storage, so an archive built on the free tier quietly ages out.
- Free collaborator licences
- After the trial an account converts to a free collaborator licence rather than being cut off, so colleagues who only read do not need paid seats.
- SOC 2, GDPR, and ISO 27001
- All three are claimed, which is a stronger published compliance set than several better-funded competitors in this band.
- SSO on Enterprise
- Single sign-on, dedicated account management, a custom support Slack channel, and data migration support sit on the Enterprise tier.
Use cases
4 documentedAccount executive losing evenings to CRM hygiene
Six calls a day, each generating a follow-up email and a set of Salesforce fields, and the admin backlog gets cleared on Sunday night or not at all.
Sybill drafts each follow-up in the rep's own voice immediately after the call and autofills 10 opportunity fields from what was said, so the admin work is a review-and-approve step instead of an evening.
Sales leader who wants deal answers, not dashboards
The forecast call is a series of verbal assurances and nobody can point to evidence that a deal is or is not progressing.
The deal workspace assembles calls, emails, Slack, and CRM into one view, and Ask Sybill with full CRM context answers why a specific deal is at risk, citing the conversations where the signal appeared.
Solo consultant or founder selling their own service
One person doing discovery, proposals, and delivery, with no budget for a sales platform and no manager to coach them.
The free tier gives unlimited recordings, the invisible recorder, 20 summaries a month, and Ask Sybill over calls and email, which is enough to run a one-person pipeline at zero cost until volume justifies Pro.
Team standardizing on Claude for internal work
Deal context lives in a sales tool nobody opens, and the AI assistant the team actually uses knows nothing about customers.
The MCP connector exposes deal context to Claude directly, so account research, follow-up drafting, and pipeline questions happen in the assistant the team already has open rather than in a separate dashboard.
Pricing
from $0 (Free), then $30 per user per month (Pro)Per-user subscription across four tiers with a genuinely usable free plan, plus a weekly credit meter on exploratory AI features while the core post-call workflow is unmetered.

Billing notes
- Sybill advertises meaningful savings on annual billing; confirm the exact annual and monthly figures at checkout, since the published pair for each tier is easy to misread.
- The weekly credit meter is per user and resets weekly rather than monthly, so a burst of heavy Ask Sybill usage in one week does not borrow against the rest of the month.
- Summaries, briefs, follow-up emails, and CRM autofill do not consume credits. Ask Sybill threads, deeper analysis, deck and dashboard generation, and API calls do.
- The free tier's real limit is a three-month data storage window plus 20 summaries a month; recordings and transcripts themselves are unlimited.
- After the 14-day Business trial expires, the account becomes a free collaborator licence rather than being locked out, so trialing does not risk losing access to past content.
- The 10-field cap on CRM autofill is a Business-tier limit; removing it requires an Enterprise quote, which is the upsell path most CRM-heavy teams will eventually hit.
Value assessment: Sybill's value is barbell-shaped. The free tier is one of the best in the category and will genuinely serve a solo seller for a long time, and Pro at $30 is a fair price for unlimited summaries in your own voice with unlimited storage. Business at $90 is a different conversation: it is triple Pro, roughly triple Grain's coaching tier, and more than Avoma's fully loaded stack, and what you get for it is CRM autofill on 10 fields, the deal workspace, and full CRM context in Ask Sybill. Whether that is good value depends entirely on how much your reps' CRM admin time is worth and how badly your opportunity records are rotting. For a team of four AEs each losing an hour a day to Salesforce, $90 pays for itself easily. For a team that wanted call coaching, it is a lot of money for the wrong feature set.
Strengths & limitations
Strengths
- A free tier with unlimited recordings and transcripts, the invisible recorder, and Ask Sybill over calls and email, which is more usable than most competitors' paid entry tiers.
- Both capture modes: an invisible recorder for discreet calls and a visible bot when disclosure and video matter, available without paying for the privilege.
- Follow-up emails and summaries written in the rep's own voice from prior winning deals, which is the difference between a draft that gets sent and one that gets rewritten.
- CRM autofill and the deal workspace attack the actual bottleneck in most small sales teams, which is that the system of record is fiction.
- The credit design is thoughtful: the daily workflow is unmetered and only exploratory AI consumes credits, so reps are never rationing the thing they use every day.
- Distributed access across browser, Slack with two-way interaction, mobile, API, and MCP means the assistant reaches the rep rather than waiting in a dashboard.
- SOC 2, GDPR, and ISO 27001 published together, which is a stronger compliance set than several better-capitalized competitors in this price band.
Limitations
- The step from Pro at $30 to Business at $90 is brutal, and the features most buyers actually want (CRM autofill, deal workspace, full CRM context) are all above that line.
- CRM autofill is capped at 10 fields on Business; removing the cap requires an Enterprise quote, which reintroduces the sales cycle the self-serve model was supposed to avoid.
- No weighted scorecard engine with custom rubric criteria, so a manager wanting structured call scoring against MEDDICC will find Avoma or Demodesk better suited.
- The credit meter is a variable cost signal even though the core workflow is exempt; heavy Ask Sybill or API users need to model it rather than assume the allocation is generous.
- The free tier's three-month storage window means an archive built on Free silently erodes, which is a quiet upgrade pressure rather than a stated one.
- US-hosted with no advertised regional data residency, which is a procurement problem for EU buyers that an EU-native vendor solves outright.
- The original behavioral and emotion-analysis positioning has faded from the marketing, so buyers who remember Sybill for that specific capability should verify it still does what they expect before purchasing.
Head-to-head comparisons
4 alternativesSybill vs Grain
from $0 (Free, capped at 20 meetings), then about $15 per seat per month on Starter billed annuallyGrain is manager-facing and cheap: coaching playlists, cross-rep talk ratio, and CRM sync for about $29 with free viewer seats. Sybill is rep-facing and expensive at the tier that matters, buying back admin time through CRM autofill and a deal workspace. If the problem is that nobody reviews calls, buy Grain. If the problem is that reps spend evenings updating Salesforce, buy Sybill and budget for the $90 tier.
Full Sybill vs Grain comparisonSybill vs Avoma
from $19 per seat per month (Startup, billed annually)Avoma sells the manager's toolkit as modules: scorecards, semantic trackers, talk-pattern analytics, and forecasting from about $53 a seat. Sybill sells the rep's toolkit: voice-matched follow-ups, autofill, and deal context, with a far better free tier. Choose Avoma when you have a methodology to enforce and score; choose Sybill when the sellers themselves are the constraint and CRM hygiene is the symptom.
Full Sybill vs Avoma comparisonSybill vs Claap
from EUR 0 (Basic), then about EUR 24 per user per month (Pro, billed annually)Claap, owned by lemlist, bundles recording, AI coaching, CRM auto-complete, and deal insights into a single EUR 48 Business plan with async video on top, which is cheaper than Sybill Business and broader in scope. Sybill goes deeper on deal context, voice-matched writing, and MCP access, and has a much better free tier. Take Claap for a European team wanting one bill; take Sybill for a US team where CRM autofill and deal reasoning are the point.
Full Sybill vs Claap comparisonSybill vs Demodesk
from EUR 25 per user per month (Capture)Demodesk gives you AI Coach with custom scorecards, deal insights, risk alerts, and CRM concierge for EUR 49 in one plan, hosted in Frankfurt under ISO 27001, which is roughly half Sybill Business with more structured coaching. Sybill counters with a real free tier, invisible capture, MCP access, and better rep-facing writing. EU buyers and coaching-first teams should take Demodesk; rep-productivity-first US teams should take Sybill.
Full Sybill vs Demodesk comparisonImplementation & onboarding
- Setup time
- Fifteen minutes to start recording. The Business features take longer: mapping the 10 autofill fields to your CRM schema and validating what the AI writes into them is a half-day of work you should not skip.
- Learning curve
- Low. Sybill is designed so reps do nothing beyond reviewing output, and the free tier means adoption can happen bottom-up before anyone signs a contract. The credit model is the only concept that needs explaining.
- Onboarding
- Fully self-serve including the Business tier, with a 14-day trial of Business features and no credit card required. Enterprise adds a dedicated account manager, a custom support Slack channel, and data migration support.
- Migration notes
- There is no bulk import of another vendor's recording archive. The migration that matters is the CRM one: decide which 10 fields autofill should own, and run it in review mode before letting it write unattended, because automated field writes on a badly mapped opportunity object create cleanup rather than saving it. Teams coming from a free note taker can adopt Sybill's free tier in parallel with zero switching cost, which makes evaluation unusually low risk.
Platform, API & security
- Platforms
- Web appInvisible desktop recorderBot for Zoom, Google Meet, and Microsoft TeamsSlackMobile appMCP connector
- API
- Public API on the Business tier and above, metered against the weekly credit allocation, plus an MCP connector so Claude and other MCP clients can query deal context directly.
- Compliance
- SOC 2GDPRISO 27001
- Data residency
- US-hosted; no regional hosting option is advertised.
- SSO
- SSO on the Enterprise tier only.
- Security notes
- Encryption in transit and at rest. The invisible recorder means capture can occur without a visible participant, which shifts the recording disclosure obligation onto the user; in two-party-consent jurisdictions you should announce recording verbally or use the bot instead. Free-tier data is retained on a three-month window while paid tiers offer unlimited storage.

Frequently asked questions
10 questionsWhat is Sybill?
Sybill is an AI sales assistant for B2B revenue teams. It records calls with either a bot or an invisible recorder, writes summaries and follow-up emails in the rep's own voice, autofills CRM fields from what was said, and maintains a per-deal workspace that can be queried through Ask Sybill in the browser, in Slack, on mobile, or from Claude via MCP.
How much does Sybill cost?
There is a free tier with unlimited recordings and transcripts, the invisible recorder, and 20 AI summaries a month. Pro is $30 per user per month and removes the summary cap and the storage window. Business is $90 per user per month and adds CRM autofill on 10 fields, full CRM context in Ask Sybill, the deal workspace, API and MCP access, and two-way Slack. Enterprise is quote-based with unlimited autofill and SSO.
What are Sybill credits and will I run out?
Credits are a weekly per-user allocation: 500 on Free, 2,500 on Pro, 5,000 on Business, unlimited on Enterprise. Importantly, meeting summaries, briefs, follow-up emails, and CRM autofill do not consume credits at all. Only Ask Sybill threads, deeper analysis, deck and dashboard generation, and API calls do. A rep using Sybill purely for post-call workflow will never see the meter; a team building dashboards or hitting the API might.
Does Sybill record without a bot?
Yes. The invisible recorder captures calls without adding a visible participant, and it is available even on the free tier. A visible bot is also available for Zoom, Google Meet, and Microsoft Teams when you want disclosure to be obvious or need video. Having both modes without paying extra is one of Sybill's genuine advantages.
How does Sybill handle two-party consent and recording law?
The invisible recorder shifts the disclosure obligation to you: there is no participant in the list announcing that recording is happening, so in two-party-consent states and under GDPR you must announce it verbally or switch to the bot, whose presence is itself notice. Sybill publishes SOC 2, GDPR, and ISO 27001 compliance, and Enterprise adds data migration support and dedicated account management for organizations that need a documented process.
Does Sybill update CRM fields automatically?
On the Business tier, yes, for 10 configured fields on the opportunity record. Pro can push summaries and notes into the CRM but not fill structured fields. Enterprise removes the 10-field cap. Field-level autofill is the single feature most Sybill buyers are actually purchasing, so budget for Business rather than Pro if that is your reason for evaluating it.
Is the seat price per recorded user or per team member?
Per user, and after the trial an unpaid account converts to a free collaborator licence rather than being disabled, so colleagues who only read do not need a paid seat. But every rep whose calls you want autofilled and analyzed on Business is a $90 licence, which is why the tier economics matter so much for team size.
Does Sybill do call scoring and coaching?
It provides rep performance insight, competitive intelligence, and judgment about what wins and loses at your company, but it is not built around weighted scorecards with custom rubric criteria. If a manager wants to score every call against a MEDDICC or SPICED rubric and track adherence, Avoma's conversation intelligence module or Demodesk's AI Coach is the better instrument, and Sybill is the better tool for the reps themselves.
How long does Sybill keep my recordings?
Free is limited to a three-month data storage window, while Pro, Business, and Enterprise provide unlimited data storage. Recordings and transcripts are unlimited in volume on every tier including Free, so the constraint is how long the archive survives rather than how much you can capture.
Who owns Sybill and how is it funded?
Sybill is an independent venture-backed company founded in 2020 by Gorish Aggarwal, Nishit Asnani, Soumyarka Mondal, and Mehak Aggarwal, headquartered in Mountain View. It has raised about $14.5M, including an oversubscribed $11M Series A led by Greycroft in July 2024, with more than 500 customers reported at that point.
Editorial verdict
Sybill is the best product in this category for the rep rather than the manager, and its free tier is the most generous entry point anyone in conversation intelligence offers: unlimited recordings, invisible capture, and a working assistant for nothing. The trouble is the shape of the paid ladder. Pro at $30 is a nice notetaker upgrade; the product Sybill actually markets, with CRM autofill, the deal workspace, and full CRM reasoning in Ask Sybill, lives at $90 a seat, which is triple Pro and more than a loaded Avoma configuration. That price is defensible if you genuinely believe your reps lose an hour a day to CRM admin, and indefensible if you were hoping for call coaching, which Sybill does not do in a structured way. Start on the free tier, which costs nothing and will tell you within a fortnight whether the writing quality and deal reasoning are worth $90 a head to you.
