Otter.ai
CallsAI meeting assistant with live transcription, summaries and meeting agents
The most widely used live transcription tool in the category, strongest on speed and note sharing, weaker on language coverage and on the privacy questions it has publicly faced.
Best for
Teams that want fast live transcription and shared meeting notes across a whole company, including non sales departments.
Not great for
Recording regulated or multilingual conversations outside its six supported languages, where consent workflows and coverage matter more than transcript speed.

Otter.ai, in plain terms
Otter.ai is an AI meeting assistant built around live transcription. Its notetaker joins Zoom, Microsoft Teams and Google Meet calls, or records from a desktop app without sending a bot into the meeting, and produces real time transcripts with speaker identification followed by summaries and action items. Otter AI Chat answers questions across past meetings and connected apps, and the 2025 and 2026 releases added agentic workflow automation, a sales notetaker on Enterprise and a live coaching agent called Live Assist. The company says more than 40 million people use it, and its press page reports passing $100 million in annual recurring revenue in 2025. Language coverage is narrower than some rivals: the homepage lists English, French, Spanish, Japanese, German and Mandarin. Pricing is per user, with a free Basic plan capped at 300 minutes a month, Pro at $8.33 per user per month on annual billing and Business at $19.99 per user per month on annual billing with a minimum of five billed seats. API access, SSO, SCIM and the SDR notetaker sit on Enterprise. Otter has also drawn documented privacy scrutiny, including a 2025 California class action alleging it recorded conversations without permission and a ban at a US university under an all party consent law.

Their published pricing in August 2026 has a free Basic plan, Pro at $8.33 per user per month on annual billing (listed at $16.99 monthly), Business at $19.99 per user per month on annual billing (listed at $30 monthly) with a minimum of five billed users, and a custom priced Enterprise plan. Check their pricing page for current figures.
Basic includes 300 minutes a month across meetings and imports, 3 lifetime file imports, one concurrent meeting, up to 5 workspace members and 20 AI Chat queries a month. The Business plan is advertised with a 7 day trial.
Their homepage lists English, French, Spanish, Japanese, German and Mandarin. French and Spanish were added in October 2024 and Japanese in November 2025 according to their press page, so coverage is narrower than notetakers claiming 100 or more languages.
Salesforce and HubSpot integrations start on the Pro plan, Business adds custom AI workflows and usage analytics, and Enterprise adds an SDR notetaker plus API access. Otter is a meeting assistant rather than a dialer or a revenue intelligence suite.
Otter reports SOC 2 Type II attestation in 2023 and HIPAA compliance in July 2025, with SSO and SCIM on Enterprise. Separately, Wikipedia documents privacy criticism, a 2025 California class action alleging that the service recorded conversations without permission, and a ban at the University of Massachusetts under an all party consent law. Recording consent rules vary by state and country.
