AI meeting transcription with speaker identification and summaries.
Audio & Voice
Otter.ai is the AI transcription tool that most people met before "AI notetaker" was a category. Founded in 2016, Otter has been transcribing meetings, lectures, interviews, and voice memos longer than most of its competitors have existed, and it has the mature transcription engine and the consumer-friendly UX to prove it. If you have ever seen a journalist or a researcher pull out their phone at the start of an interview and hit record, there is a fair chance they were opening Otter.
The one-line positioning: Otter is the notetaker for people who want transcription first and enterprise integration second. It came from a consumer and prosumer heritage — students recording lectures, journalists recording interviews, podcasters transcribing episodes — and its center of gravity is still transcription accuracy and mobile-first capture. It has since built out meeting integrations, an assistant called OtterPilot, and a real business tier that competes with Fireflies for revenue-team spend. But the DNA is different, and the tool feels different to use.
Where Fireflies.ai is a conversation intelligence platform that happens to transcribe, Otter is a transcription platform that happens to do conversation intelligence. Both are legitimate positions. Otter wins on transcription quality and mobile capture. Fireflies wins on CRM integrations, cross-platform breadth, and the archive-wide assistant. The two products serve overlapping but not identical audiences, and the "which one should I buy" question turns on what you actually do with the transcripts once you have them.
In 2026 Otter has doubled down on OtterPilot — an assistant layer that not only summarizes meetings but attempts to answer questions, draft follow-up emails, and act as a real meeting assistant during and after the call. Some of this is impressive. Some of it is the same "AI chat over your meetings" pattern that every competitor now ships. The core transcription engine remains Otter's real moat.
High-accuracy transcription. Otter's transcription engine is one of the two or three most accurate in the category on clean English audio, and it holds up better than most competitors on accented English and noisy environments. This is the reason to be here.
OtterPilot. The AI assistant that auto-joins Zoom, Google Meet, and Microsoft Teams meetings, transcribes them, produces a summary with action items, and answers questions about the meeting in a chat sidebar. Comparable in shape to Fireflies' bot but with a lighter-weight feel — the OtterPilot bot is less visible in the meeting UI, and the post-meeting summary lands in your dashboard with a cleaner interface.
Otter AI Chat. The workspace-wide chat that answers questions across your meetings. "What did we decide about the launch date?" pulls from every relevant transcript and answers with citations. Similar to Fireflies' AskFred; comparable quality; Otter's is cleaner in presentation and slightly less capable in cross-meeting synthesis.
Live transcription. Real-time captions during meetings, useful for accessibility and for people who process spoken content better in written form. The live transcript is available on desktop and mobile.
Mobile capture. Otter's iOS and Android apps are genuinely good — designed for the "I need to record this conversation right now" moment. Journalists, students, and researchers rely on this. Fireflies and tl;dv are meeting-first; Otter is universal-capture-first, which shows in the mobile experience.
Speaker identification. Otter learns to recognize individual voices over time. Once trained on your voice and your team's voices, speaker attribution is accurate even on shared mics. Training takes a few hours of tagged audio per person.
Automatic slide capture. During Zoom and Meet screen shares, Otter captures slides and inserts them into the transcript at the moment they appeared. Useful for research and for meetings where the slides carry more information than the spoken words.
Meeting summaries. Auto-generated at meeting end. Structured as a topic-based recap with action items and decisions. Summary quality is good but not best-in-class; tl;dv and Granola produce cleaner narrative summaries in our testing.
Integrations. Salesforce and HubSpot CRM sync, Slack notifications, Notion export, Microsoft Teams and Google Workspace, Zapier for the long tail. CRM integrations are functional but not as deep as Fireflies'.
OtterPilot for Sales. The revenue-team layer — pushes meeting notes into CRM opportunities, extracts objections and next steps, generates follow-up email drafts. Priced separately from the general Business plan; a step above OtterPilot in capability and cost.
Vocabulary. Custom vocabulary — names, product terms, industry jargon — that Otter learns for your account. Meaningfully improves transcription accuracy in specialized domains.
Import audio and video files. Upload any recording — a podcast episode, an interview from a different platform, a phone call — and Otter transcribes it. Length limits apply per plan.
Otter for Education. A dedicated tier and workflow for students and educators. Lecture recording, live captions, study notes generation. Under the hood, the same product as the business version, with pricing and features tuned for the education buyer.
Otter's pricing has simplified over 2025 into a cleaner tier structure with a real free plan and paid tiers priced against Fireflies.
Free ($0) — 300 minutes of transcription per month, 30 minutes per conversation, import 3 audio or video files lifetime, basic AI features. Enough to evaluate the transcription quality and OtterPilot behavior.
Pro ($16.99/user/month, billed annually) — 1,200 minutes per month, 90 minutes per conversation, unlimited imports, OtterPilot for meetings, Otter AI Chat, custom vocabulary. Monthly billing is $20/user/month.
Business ($30/user/month, billed annually) — 6,000 minutes per month, 4-hour conversation length, admin controls, usage analytics, join Zoom/Meet/Teams automatically, CRM integrations. Monthly billing is $40/user/month.
Enterprise (custom) — SSO, SAML, video conferencing controls, advanced security, custom retention, HIPAA where applicable.
OtterPilot for Sales (add-on) — Additional per-seat cost on top of Business, currently $40/user/month annual. Enables deeper CRM sync and sales-specific workflows.
| Feature | Free | Pro | Business | Enterprise |
|---|---|---|---|---|
| Monthly minutes | 300 | 1,200 | 6,000 | Custom |
| Meeting length cap | 30 min | 90 min | 4 hr | 4 hr+ |

Otter's Pro tier at $16.99/user/month is slightly cheaper than Fireflies.ai Pro. The Business tier is priced roughly in line. The OtterPilot for Sales add-on is where the total cost for a sales team lands close to or above the Fireflies Business tier.
Pros.
Cons.
Journalists, researchers, and students. The heritage buyer, and still the buyer Otter serves best. Field recording, interview transcription, lecture capture. Free or Pro is enough. Mobile capture, custom vocabulary, and transcription accuracy are the reasons.
Solo founders and consultants recording customer conversations. Otter's Pro tier at $16.99/user/month with 1,200 minutes per month covers most solo operators, and the mobile capture handles the coffee-shop customer interview case that meeting-first tools miss.
Small teams that value transcription quality above CRM depth. Product teams, design research groups, editorial teams. Otter Business at $30/user/month is competitive with Fireflies and often preferred when the CRM sync is not the main use case.
Accessibility-first teams. Live captions in meetings help deaf and hard-of-hearing team members participate in real time. Otter is the leader in this category — it is what many organizations settle on when accessibility is a hard requirement.
Educators and universities. Otter for Education is a real product with a real user base. Lectures transcribed automatically, students get search across the semester, instructors get analytics on what topics generated the most questions.
Bad fit. Revenue teams with heavy CRM workflows — Fireflies is stronger there. Teams that run on Webex or other non-Zoom/Meet/Teams platforms. Buyers who need best-in-class summary quality — tl;dv or Granola beat Otter on that specific axis. Teams culturally opposed to bots joining meetings — Granola is the alternative.
Fireflies.ai. The direct competitor. Fireflies is stronger on CRM integrations, cross-platform breadth, and archive intelligence. Otter is stronger on transcription accuracy, mobile capture, and consumer-friendly UX. For revenue teams Fireflies usually wins; for research, education, and general professional transcription Otter usually wins.
tl;dv. The summary-quality competitor. tl;dv's meeting summaries and highlight clips are cleaner than Otter's, though transcription accuracy is comparable and cross-platform breadth is narrower.
Granola. The no-bot alternative. Runs on your device, no Otter-style bot joins the meeting, you type sparse notes and Granola enriches them. Preferred by teams that dislike the ambient-recording posture. Trades transcription completeness for a lighter meeting UX.
Rev.ai and Descript. For pure audio transcription — podcasts, interviews, video editing — Rev and Descript are stronger. Descript in particular is the pick for content creators editing video with the transcript as the source of truth.
Zoom AI Companion. Native summarizer inside Zoom, free with existing subscriptions. Enough for single-platform teams that do not need archive search or cross-tool integration.
Google Meet Gemini and Microsoft Teams Copilot. Same shape as Zoom AI Companion for the other two dominant platforms. Fine for basic post-meeting recaps; noticeably weaker than Otter or Fireflies for archive-wide use.
Sign up at https://otter.ai with Google, Microsoft, or email. The onboarding walks you through calendar connection and OtterPilot setup.
Install the mobile app. Otter's mobile UX is the reason many users stay — even if you never plan to record with your phone, having it available for the ad-hoc meeting or hallway conversation is worth the two minutes of setup.
Record or import one real conversation. Do not use a demo. Bring an actual meeting or interview and evaluate transcription accuracy on your real accents, jargon, and audio conditions. This is the fair test.
If the transcription quality clears your bar, connect your calendar to enable OtterPilot auto-join. Configure whether OtterPilot joins all meetings, only your organized meetings, or only external meetings — same tradeoff as Fireflies.
Add custom vocabulary — product names, team member names, industry jargon. This is a fifteen-minute setup that noticeably improves accuracy from meeting one.
Set up two integrations: your team collaboration tool (Slack or Notion) and, if you are a revenue team, your CRM. Push meeting summaries to Slack channels to make them team-visible.
Wait a few weeks before evaluating Otter AI Chat over the archive. Like AskFred, it needs a critical mass of recorded conversation before it becomes useful.
Is Otter more accurate than Fireflies at transcription? On clean English audio, generally yes — by a small but noticeable margin. On accented English or noisy environments, Otter's advantage widens. Both are strong; if transcription accuracy is your top criterion, Otter is the pick.
Which mobile app is better? Otter's, by a clear margin. Fireflies' mobile app exists but is meeting-review-focused. Otter's app is designed for field capture and interview recording, and it shows.
Does Otter work without joining meetings as a bot? OtterPilot is the bot-based mode. You can also record via the desktop or mobile app without any bot in the meeting — you capture your own device audio. The bot mode is what enables auto-join and screen-share slide capture; the direct-recording mode is available for teams that prefer it.
How does Otter handle non-English languages? English is the strongest by a wide margin. Spanish and French are usable for internal work. Other languages are inconsistent and should be tested before committing.
Is the free tier enough? For solo use under about ten meetings a month, yes. Past that, Pro at $16.99/user/month is the upgrade. Business is only worth it for teams that need CRM integrations, auto-join, and longer meeting caps.
Can Otter transcribe phone calls? Yes, via mobile capture — record the phone call using the Otter app. There is no dial-in bot like Fireflies has, so this is manual capture rather than automatic.
Does OtterPilot for Sales replace a full sales-enablement tool? No — it is a notetaker with CRM sync, not a Gong or Chorus replacement. For deep call-coaching and conversation intelligence at scale, Gong is still the enterprise standard.
Otter is the right notetaker for teams and individuals whose priority is transcription accuracy, mobile capture, and clean AI chat over meeting archives — not deep CRM workflows. It has been the transcription workhorse for journalists, researchers, students, and general professional users since before "AI notetaker" was a category, and that heritage shows in the quality of the core engine and the mobile experience.
For revenue teams with heavy CRM integration needs, Fireflies.ai is usually the sharper pick — the CRM sync is deeper and the sales-team surface is priced better than Otter's Business + OtterPilot for Sales add-on. For teams that dislike the always-on bot posture, Granola is the alternative that keeps the meeting clean. For teams whose primary need is highlight-clip and summary quality rather than transcription depth, tl;dv is stronger there.
Start at https://otter.ai with the free tier. Bring a real conversation — not a demo — and evaluate transcription quality on your actual audio. If it clears your bar, Pro at $16.99/user/month is the standard solo path and Business at $30/user/month is the standard team path. Otter is not the flashiest tool in the category, but for buyers who value transcription accuracy above everything else, it remains one of the two safest picks on the market.
