What is Otter.ai?

Otter.ai is an AI transcription and meeting assistant. It automatically joins your Zoom, Google Meet and Microsoft Teams calls, transcribes everything in real time, generates a summary with action items, and gives you a searchable archive of every meeting you have ever recorded. Over 15 million users have used Otter.ai, and it has transcribed over a billion meetings.

The core value is simple: instead of splitting your attention between participating in a meeting and taking notes, you participate fully and let Otter handle the record. The transcript and summary are ready immediately after the meeting ends. You can search back through months of meetings in seconds using any keyword.

In 2026, Otter added OtterPilot — an AI agent that joins meetings automatically, takes notes, and can join up to 3 concurrent meetings simultaneously on Business plans. It also added an MCP Server, allowing Claude, ChatGPT and other AI tools to access your Otter meeting archive for deeper analysis and workflow integration.

What Otter does

Real-time transcription — Transcribes speech to text as people talk. Accuracy is approximately 85% on clear English audio with multiple independent sources confirming this. Drops in noisy environments and with heavy accents.

Speaker identification — Labels who said what in multi-speaker meetings. Requires training (Otter learns voices over time) or manual labelling in the first few sessions.

Automatic summaries — After each meeting, Otter generates a summary and extracts action items. Quality varies — summaries are most useful for straightforward meeting types (standups, status updates) and less reliable for complex discussions.

OtterPilot — AI bot that joins meetings automatically when they appear on your connected calendar. Starts transcribing when the meeting begins, stops when it ends, posts the transcript and summary to the meeting host.

Search across all meetings — Full-text search across your entire meeting archive. Find every time a specific topic, decision or person's name was mentioned across all recorded calls.

Otter AI Chat — Ask natural language questions across your meeting archive. "What did we decide about the Q2 budget?" searches across all transcripts to find the relevant discussion.

Language support — English, French and Spanish. This is a genuine limitation for international teams.

Who Otter.ai is for

Professionals who spend significant time in meetings and need accurate records without manual note-taking. Sales teams needing searchable records of customer calls. Researchers and journalists transcribing interviews. Students recording lectures. Anyone whose work depends on accurate recall of what was said and decided in meetings.

Is Otter.ai free?

Yes. The Free plan includes 300 minutes of transcription per month with a hard 30-minute cap per conversation. This cap is a real limitation — most business meetings run longer. Pro is $8.33/user/month (annual) or $16.99/month monthly, with 1,200 minutes per month and 90-minute conversation limit. Business is $19.99/user/month for 6,000 minutes and 4-hour limits.

Getting started

Go to otter.ai and sign up free. Connect your Google or Microsoft calendar to enable OtterPilot automatic joining. Install the browser extension for Zoom and Google Meet if you want Otter to join calls automatically. For manual use: open Otter on your phone or browser and tap Record before a meeting starts.

12 Otter.ai use cases

Automatic meeting notes
Connect your calendar to Otter. OtterPilot joins every meeting automatically, transcribes, and emails you the summary and action items when it ends. You attend the meeting without taking a single note. The searchable transcript is available immediately after.
Sales call records
Every customer call is automatically transcribed and archived. After each call: review the action items Otter extracted, check what the customer said about competitors, pricing objections or timeline. Use Otter AI Chat to query across all your customer calls: 'Which customers mentioned budget concerns this month?'
Interview transcription
Before conducting an interview: open Otter on your phone and tap Record. Otter transcribes as you talk. After the interview: review the transcript, highlight key quotes, export the full text for further editing. Faster than manual transcription; better than relying on memory.
Research multiple transcripts
Upload recordings of 5–10 interviews or focus groups. Use Otter AI Chat across all of them: 'What themes came up most frequently?' or 'What did participants say about [specific topic]?' This is qualitative research synthesis at speed that would otherwise take days of manual reading.
Lecture notes
Open Otter on your phone in class. It transcribes the lecture in real time. After class: read the transcript to fill in gaps from your handwritten notes. Use the search to find specific concepts when revising. The transcript is your insurance against missing important points during fast-paced lectures.
Action item extraction
After any meeting: go to Meeting Gems and review extracted action items. Assign each to the relevant person. Export the action items list to your project management tool or email it to attendees as a follow-up. This replaces the manual follow-up email that often gets delayed or forgotten.
Search past meetings
You remember discussing something important three weeks ago but cannot remember which meeting. Open Otter search. Type the keyword — the product name, the decision, the person's name. Otter shows you every meeting where it was mentioned, with links to the exact timestamp. This pays for itself the first time you find something important you would otherwise have spent an hour searching for.
Podcast transcription
Upload your podcast audio files (MP3, WAV, M4A) to Otter for transcription. On Pro: up to 10 file imports per month. Use the transcript for show notes, blog posts, searchable episode pages, and social media quote graphics. Turns every episode into a body of written content.
Concurrent meetings (Business)
On Business plan: OtterPilot can attend up to 3 meetings simultaneously. For an executive attending multiple parallel sessions, or a sales manager with team members in simultaneous calls — all are transcribed and summarised without any one being missed.
MCP integration
Connect your Otter archive to Claude or ChatGPT via Otter's MCP Server. Ask your AI assistant: 'Based on my Otter meeting transcripts, what are the most common objections our sales team is hearing this quarter?' The AI reads across your entire meeting history to answer. Requires technical setup but transforms Otter from a note archive into a queryable knowledge base.

Tips

Know the minute limits before relying on it. The Free plan's 30-minute conversation cap means Otter stops transcribing mid-meeting for anything longer. Pro's 90-minute cap covers most meetings but not all. Check your typical meeting length against the plan limit before the day you rely on it for something important.

Train speaker identification. After your first few meetings, label speakers in Otter manually. Otter learns these voice profiles and improves its automatic speaker identification over time. 15 minutes of labelling early on saves constant corrections later.

The 10 file import cap on Pro is a real constraint for content creators. If you need to transcribe more than 10 recorded files per month (podcast episodes, recorded interviews), you will need Business tier. Factor this in when evaluating plans.
