As of May 2026, Fireflies.ai and Otter.ai occupy adjacent but distinct positions in the AI meeting notes category.
Both deploy a visible bot into Zoom, Google Meet, and Microsoft Teams to record, transcribe, and summarize meetings — but the philosophies behind each product have diverged significantly since both launched in 2016.
Fireflies.ai achieved unicorn status in June 2025 following the launch of 'Talk to Fireflies,' a Perplexity AI-powered voice assistant that performs real-time web searches during live meetings.
By early 2026, the platform added Live Assist — real-time coaching suggestions mid-call — and a Fireflies MCP integration that pipes meeting data into external AI tools like Claude and ChatGPT. These additions push Fireflies clearly into conversation-intelligence territory.
Its integration breadth is unmatched at this price point: 100+ native connections spanning Salesforce, HubSpot, Pipedrive, Slack, Notion, Asana, Zapier, and a full GraphQL API for custom workflows.
Transcription accuracy sits at approximately 94–95% in optimal conditions, with notably better speaker diarization than Otter in crosstalk-heavy meetings. It supports 100+ languages — a significant edge for globally distributed teams. The free tier provides 800 minutes of storage, more runway than Otter's 300 minutes.
Otter.ai remains the category's original pioneer and a genuine rival on specific dimensions. OtterPilot 3.0 captures screen-shared slides and embeds them at the exact transcript timestamp they were discussed — a feature Fireflies lacks.
Otter AI Chat spans the entire meeting library without metering: ask questions across months of meetings with no credit cap. In clean, single-speaker English audio, independent testers found Otter marginally ahead on raw word accuracy.
Its Pro plan's 90-minute conversation limit and 1,200 monthly minutes cap are meaningful constraints for heavy users. Otter's language support tops out at English, French, and Spanish for live transcription — a hard ceiling that disqualifies it for multilingual teams.
The critical risk factor any procurement team must weigh: in August 2025, a consolidated federal class-action lawsuit (In re Otter.AI Privacy Litigation, N.D.
Cal., 5:25-cv-06911) was filed against Otter.ai, alleging OtterPilot recorded private conversations without all-participant consent and used them to train its speech recognition models. Four separate suits were consolidated in October 2025.
As of May 2026, the litigation is ongoing and no final judgment has been issued.
Fireflies, by contrast, maintains a 0-day data retention policy with third parties, is HIPAA compliant at the Enterprise tier, and explicitly does not train on customer data — a material privacy differentiator for healthcare, legal, and regulated-industry buyers.
For sales teams, RevOps, and organizations that need CRM auto-sync, cross-call search, and multilingual coverage, Fireflies.ai wins.
For individuals, journalists, educators, and teams that prize live captions in Zoom, slide capture, and uncapped AI Chat queries, Otter.ai remains the stronger fit — with the caveat that its ongoing privacy litigation demands legal review before enterprise deployment.
Sales teams & CRM automation
Fireflies.ai
Fireflies.ai's Business tier includes automatic CRM sync to Salesforce, HubSpot, and Pipedrive, plus talk-time ratios, sentiment analysis, and topic tracking — conversation-intelligence features Otter.ai gates entirely behind its Enterprise tier or does not offer at all.
Real-time live captions & slide capture
Otter.ai
Otter.ai's OtterPilot 3.0 displays live captions visible to all Zoom participants and embeds screen-shared slides directly into transcripts at the exact timestamp discussed — two in-meeting features Fireflies.ai does not replicate.
Multilingual & global teams
Fireflies.ai
Fireflies.ai supports transcription in 100+ languages with automatic language detection, while Otter.ai's live transcription is limited to English, French, and Spanish — a hard ceiling that disqualifies Otter for non-English-speaking organizations.

- Integration breadth spans 100+ apps including Salesforce, HubSpot, Pipedrive, Slack, Notion, Asana, and Zapier, plus a fully documented GraphQL API for custom automations — the widest connector ecosystem in the category at the Pro and Business tiers.
- AskFred GPT-powered assistant answers natural-language questions about any meeting transcript; 'Talk to Fireflies' (Perplexity AI-powered, launched June 2025) adds real-time web-search capability during live calls.
- Live Assist (launched 2026) delivers real-time coaching suggestions mid-call; Fireflies MCP integration (also 2026) pushes meeting data directly into Claude, ChatGPT, and Devin with a single click.
- HIPAA compliance at the Enterprise tier, SOC 2 Type II and GDPR across all paid tiers, a documented 0-day data retention policy with third parties, and an explicit no-training-on-customer-data policy.
- Free tier provides 800 minutes of storage per seat — nearly three times Otter's 300-minute free allocation — giving evaluators substantially more runway before committing to a paid plan.
Cons
- AI credits system governs AskFred, custom summaries, Magic Soundbites, and CRM Autofill: the Pro tier gets 20 credits per month, Business 30, Enterprise 50. Heavy users exhaust credits before month-end and must purchase add-on packs.
- Pro tier storage is capped at 8,000 minutes per seat; teams recording multiple meetings daily can fill this in four to five months, forcing an upgrade to the Business tier for unlimited storage.
- Conversation intelligence features — talk-time ratios, sentiment analysis, topic trackers — are locked behind the Business tier; the Pro tier has no analytics layer at all.
- Visible bot labeled 'Fireflies.ai Notetaker' joins every meeting as a participant; external clients and prospects notice its presence, which can affect dynamics in sensitive sales or negotiation calls.
- No native per-conversation Zoom live caption stream visible to all participants — a specific accessibility feature that Otter.ai delivers natively within Zoom.

Otter.ai
ProductivityPros
- OtterPilot 3.0 captures screen-shared slides and embeds them into transcripts at the exact timestamp they were discussed, providing visual meeting context that Fireflies.ai does not offer.
- Live captions visible to all Zoom participants during meetings via native Zoom integration — a unique accessibility and real-time alignment feature among major AI notetakers.
- Otter AI Chat queries the entire meeting library with no monthly credit cap or metering; cross-meeting questions like 'What did customers say about pricing in Q1?' return attributed answers instantly.
- Free tier includes 300 minutes per month with speaker identification, automated summaries, and real-time transcription — a genuinely functional starting point for individual contributors and students.
- OtterPilot for Sales (Enterprise tier) automatically extracts deal insights and pushes action items as Salesforce tasks, providing structured CRM write-back beyond simple activity-log syncing.
Cons
- Live transcription limited to English, French, and Spanish — no support for the 90+ additional languages Fireflies.ai covers, disqualifying Otter for multilingual or globally distributed teams.
- Pro tier imposes a 90-minute per-conversation cap and 1,200 monthly minutes total; independent testers reported losing the final 30 minutes of a 2-hour workshop when the per-conversation limit was hit mid-meeting.
- A consolidated federal class-action (In re Otter.AI Privacy Litigation, N.D. Cal., filed August 2025, consolidated October 2025) alleges OtterPilot recorded participants without all-party consent and used recordings to train AI models — active litigation as of May 2026 that demands legal review before enterprise deployment.
- OtterPilot for Sales is restricted to the Enterprise tier with custom pricing; Pro and Business users have no access to sales-specific CRM write-back or deal intelligence features.
- API access is largely gated behind the Enterprise tier with sparse public documentation, making custom workflow automation significantly harder compared to Fireflies.ai's publicly documented GraphQL API.
- Otter's privacy policy acknowledges training its language models on de-identified user data by default — a meaningful contrast to Fireflies.ai's explicit no-training-on-customer-data policy.

Frequently asked
Fireflies.ai vs Otter.ai FAQs
Quick answers to the questions readers ask before picking between these two.
Which is more accurate, Fireflies.ai or Otter.ai?
Fireflies.ai edges ahead in real-world multi-speaker meetings. Independent side-by-side testing on 20 meetings found Fireflies scored approximately 94% word-level accuracy versus Otter's 93–94%, with the more meaningful difference in speaker attribution during crosstalk — Fireflies maintains correct speaker labels when participants talk over each other, while Otter tends to merge overlapping speech into a single speaker. In clean, single-speaker English audio, Otter is marginally stronger by about one percentage point.
Does Fireflies.ai support more languages than Otter.ai?
Yes, significantly. Fireflies.ai transcribes in 100+ languages with automatic language detection. Otter.ai's live transcription is limited to English, French, and Spanish as of May 2026. For any team with non-English-speaking participants or globally distributed members, Fireflies.ai is the only viable option of the two.
Which tool has better CRM integration, Fireflies.ai or Otter.ai?
Fireflies.ai wins on CRM breadth and accessibility. Its Business tier automatically syncs meeting notes, action items, and sentiment scores to Salesforce, HubSpot, and Pipedrive without manual data entry, and the GraphQL API enables custom automations. Otter.ai's OtterPilot for Sales — which pushes action items as Salesforce tasks — is locked behind the Enterprise tier with custom pricing, making it inaccessible to teams on the Pro or Business plans.
Is the Otter.ai privacy lawsuit a reason to switch to Fireflies.ai?
It warrants serious evaluation for enterprise and regulated-industry buyers. The consolidated federal class action In re Otter.AI Privacy Litigation (N.D. Cal., filed August 2025) alleges OtterPilot recorded meeting participants without all-party consent and used recordings to train its models — allegations Otter contests and which remain unresolved as of May 2026. Fireflies.ai documents a 0-day third-party data retention policy, does not train on customer data, and holds HIPAA compliance at the Enterprise tier. Organizations in healthcare, legal, or finance should factor these differences into procurement decisions.
Which tool is better on the free plan — Fireflies.ai or Otter.ai?
Fireflies.ai's free tier provides 800 minutes of storage per seat versus Otter.ai's 300 minutes per month with a 30-minute per-conversation cap. However, Otter's free plan includes real-time transcription and speaker identification with no per-conversation time pressure during evaluation. Fireflies restricts AI summaries and CRM integrations on the free tier. For raw evaluation volume, Fireflies gives nearly three times more recording runway.
Which AI meeting notetaker is better for students and educators?
Otter.ai is the stronger choice for academic use. Its origins were in university classrooms, OtterPilot 3.0 captures lecture slides and embeds them into transcripts at the moment they were displayed, and Otter offers a 20% discount on Pro plans for verified .edu email addresses. Fireflies.ai is primarily designed for business meeting workflows and lacks comparable slide-capture or education-specific pricing.
Can Fireflies.ai or Otter.ai transcribe in-person meetings?
Both can, with caveats. Fireflies.ai launched a standalone desktop app in 2026 for capturing in-person conversations and supports audio file uploads including MP3 and WAV. Otter.ai supports in-person transcription via iOS and Android mobile apps. Neither is as optimized for in-person use as for virtual meetings, where bot-joining eliminates audio-quality variability inherent in room microphones.
Bottom line
Choose Fireflies.ai if your team's primary use case involves sales calls, customer success, or any workflow where CRM auto-sync, cross-call search, and multilingual coverage are requirements.
The Business tier's conversation intelligence layer — talk-time ratios, sentiment analysis, topic trackers — delivers capabilities that dedicated revenue-intelligence platforms charge an order of magnitude more for. Teams using Salesforce or HubSpot will find the post-call automation alone justifies the per-seat cost.
RevOps and sales managers who want a searchable, org-wide call library with a full GraphQL API for custom automations should start here.
Choose Otter.ai if your meetings are predominantly English-language, you need live captions visible to all Zoom participants, or your team relies heavily on cross-meeting AI queries without worrying about credit caps.
Journalists, UX researchers, educators, and knowledge workers who conduct interviews or lectures will find Otter's OtterPilot 3.0 slide capture and uncapped AI Chat well-suited to their workflows. The free tier is sufficient for light individual use.
For regulated industries — healthcare, legal, financial services — Fireflies.ai's HIPAA compliance, 0-day third-party data retention policy, and explicit no-training-on-customer-data stance make it the lower-risk choice.
Otter.ai's active federal class-action litigation (In re Otter.AI Privacy Litigation) is not a verdict, but it is a compliance flag that procurement and legal teams at enterprise organizations cannot ignore as of May 2026.
For budget-conscious individual contributors who just need clean transcripts, Fathom — with its unlimited free tier and a 5.0/5 G2 rating from over 6,000 reviews — is worth evaluating alongside both tools.
But for teams choosing between Fireflies.ai and Otter.ai specifically, the split is clear: Fireflies wins on integration depth, language coverage, privacy posture, and sales workflow automation; Otter wins on real-time in-meeting intelligence, slide capture, and uncapped cross-meeting AI queries.
