Otter.ai is an AI-powered transcription and meeting-notes platform founded in 2016 (originally as AISense) by Sam Liang and Yun Fu, two AI engineers based in Mountain View, California. The core product, OtterPilot, automatically joins scheduled Zoom, Microsoft Teams, and Google Meet calls, produces a live transcript as people speak, and generates a post-meeting summary with an outline, key topics, and action items. Otter also supports manual recording via its iOS/Android apps and Chrome extension, and can transcribe uploaded audio or video files. The company reports usage by more than 35 million people across over a billion meetings, positioning it among the most widely adopted AI notetakers on the market.
What differentiates Otter from simpler transcription tools is its shift toward a broader "conversational knowledge" layer: Otter AI Chat lets users ask questions across one meeting or their entire meeting history, and the platform now offers use-case-specific agents for sales (CRM sync, follow-up drafting), education, media, recruiting, and SDR outreach. Speaker identification, custom vocabulary, automated slide capture during screen shares, and searchable/exportable transcripts round out the core experience. Otter integrates with Slack, Salesforce, HubSpot, Zapier, and as of 2026 exposes an MCP server and API/webhooks for enterprise workflows, reflecting its push from a consumer note-taking app toward an enterprise meeting-intelligence platform.
Otter.ai is best suited for individuals, sales teams, recruiters, journalists, and students who take frequent meetings or interviews and want automatic transcription plus searchable summaries without paying for a premium tier immediately. It's a weaker fit for teams needing near-perfect accuracy in noisy, multi-accent, or highly technical conversations, or for larger organizations that have already outgrown its per-minute pricing model and need unlimited enterprise-grade capture with minimal manual cleanup.

Pros and cons
Pros
- The free Basic plan (300 minutes/month) is genuinely usable on its own, which is a common reason reviewers cite for choosing Otter over competitors that gate transcription entirely behind a paywall.
- For clean, single-speaker or well-separated audio, transcription accuracy is strong enough that Capterra reviewers describe it as their primary substitute for manual note-taking.
- Native auto-join for Zoom, Microsoft Teams, and Google Meet means most users never have to remember to start a recording.
- Automated summaries and action items save meaningful review time, particularly praised by project managers and consultants in verified reviews.
- Search across past transcripts and the newer Otter AI Chat make it easy to find what was said in a specific meeting weeks later.
- Mobile apps support in-person recording, which several reviewers highlighted as valuable for interviews and in-office conversations.
Cons
- Multiple Capterra and G2 reviewers report that accuracy degrades noticeably with overlapping speakers, accents, or background noise, sometimes requiring manual correction of entire passages.
- Speaker identification is inconsistent in group settings; users report Otter mislabeling or merging speakers, especially on first use before custom vocabulary is trained.
- The Basic and Pro minute caps (300 and 1,200 minutes/month respectively) are frequently cited as too low for people in back-to-back meetings all day.
- Some reviewers found the auto-join behavior intrusive, joining calendar events that weren't actual meetings until manually disabled per-event.
- Compared to newer competitors like Fireflies or Fathom, some users feel Otter's action-item detection and deeper context understanding lag behind, prompting churn to alternatives.
What reviewers say
Otter.ai holds consistently strong ratings (4.4/5 on both G2 and Capterra), with reviewers praising ease of use and time savings while flagging accuracy issues in noisy or multi-speaker conditions.
Frequently praised
- Real-time transcription and ease of use that lets people focus on the conversation instead of note-taking

- Strong free tier and affordable Pro pricing relative to competitors
Frequently criticized
- Transcription accuracy drops with background noise, accents, or crosstalk
- Speaker identification requires manual correction, especially in group meetings
