Our 30-Second Verdict
Otter.ai is the best AI meeting assistant if you want to read transcripts live, during the meeting. It's the category's incumbent and still has the best real-time speech-to-text experience — live captions appear within a second, the iOS and Android apps are polished, and the in-call "OtterPilot" sidebar lets you follow crosstalk in real time. But for post-meeting workflows (summaries, action items, searchable history), Fireflies is now slightly better and substantially cheaper. Pay for Otter if live captions matter; pay for Fireflies if they don't.
Overview: What Is Otter.ai?
Otter.ai was founded in 2016 by Sam Liang and Yun Fu and built its reputation on best-in-class real-time speech recognition. Originally a standalone transcription app, Otter evolved into a full meeting assistant with OtterPilot (auto-join of Zoom, Meet, and Teams calls), AI summaries, and the "Otter Chat" interface that lets you ask questions about past meetings. In 2026, Otter serves millions of individual users and thousands of teams, with strong adoption in academia, journalism, and education.
Key Features
Real-Time Transcription & Live Captions
Otter's signature feature. During a Zoom, Google Meet, or Microsoft Teams call, Otter shows live captions with speaker labels, and they're usable — fast enough to read during crosstalk, accurate enough to quote. If you're deaf, hard-of-hearing, or non-native in the meeting's primary language, Otter's live transcription is a material accessibility feature, not a gimmick.
OtterPilot Auto-Join
Connect your Google or Outlook calendar and OtterPilot automatically joins every scheduled meeting, transcribes it, and emails you the summary. You can control which meetings it joins via rules (e.g., "skip 1:1s," "only meetings I organize").
AI Summaries & Action Items
Otter generates meeting summaries and extracts action items automatically. In our testing, the summaries were solid but not the category's best — Fireflies produces cleaner bullet structures and more reliably captures decisions. Otter's action item extraction is good on formal meetings, mediocre on casual ones.
Otter Chat
Ask questions across your entire meeting history in natural language: "What did Maya say about the Q2 launch date?" or "Summarize every call we had with Acme Corp." This works well once you have enough meeting history, though it's less impressive than similar features from purpose-built knowledge tools.
Pricing Breakdown
| Plan | Price | Key Inclusions |
|---|---|---|
| Basic (Free) | $0 | 300 minutes/mo, 3 imported files, 30-min limit/conversation |
| Pro | $17/user/mo | 1,200 minutes/mo, advanced search, custom vocabulary |
| Business | $30/user/mo | 6,000 minutes/mo, team features, admin controls, priority support |
| Enterprise | Custom | SSO, SCIM, custom retention, DPA |
At $17/month Pro, Otter is $7/month more expensive than Fireflies' equivalent plan. For most users, that's not justified unless you specifically need the live transcription experience. The free Basic plan is usable for occasional note-taking but the 300-minute monthly cap runs out fast.
AI Capabilities
Otter runs a proprietary speech recognition model tuned over nearly a decade of meeting audio — that's why real-time accuracy is strong. The summary and chat features use LLMs on top (Otter hasn't disclosed which). In our tests, summary quality was comparable to GPT-4o-class output, but noticeably less structured than Fireflies' default summaries.
Privacy
Otter stores both audio and transcripts by default. You can delete conversations, but the default retention is indefinite. For Business and Enterprise plans, you can configure retention policies. Otter's privacy posture is adequate for non-regulated use but does not match the data-residency and processing guarantees you'd want for legal, medical, or EU-sensitive meetings. Read our meeting assistant privacy guide before using Otter with client meetings.
Pros & Cons
Strengths
- ✓ Best-in-class real-time transcription
- ✓ Accessibility-grade live captions
- ✓ Polished iOS and Android apps
- ✓ OtterPilot auto-join works reliably
- ✓ Good cross-meeting search and chat
- ✓ Strong speaker diarization on clean audio
Weaknesses
- ✗ More expensive than Fireflies for similar post-meeting features
- ✗ Summaries less structured than competitors
- ✗ Default data retention is indefinite
- ✗ Free plan cap is tight (300 min/mo)
- ✗ Limited workflow integrations vs Fireflies
Who Should Use Otter?
Otter is ideal for anyone who needs real-time live transcription during meetings — deaf and hard-of-hearing users, non-native speakers in English meetings, journalists transcribing interviews live, and academic researchers. It's also strong for solo users who prefer Otter's polished mobile apps over Fireflies' web-first experience.
Otter is not the best choice if you only care about post-meeting summaries and action items (use Fireflies), if you want the lightest-touch privacy footprint (use Granola), or if you need deep workflow integrations with CRMs and task managers (use Fireflies or Grain).
Verdict
Otter.ai earns our Best Real-Time Transcription pick for 2026. Nearly a decade of investment in speech recognition shows: Otter is still the tool we'd choose if we absolutely needed to read a meeting as it happens. For most other jobs, Fireflies is a better value — but "most other jobs" isn't "every job," and the jobs Otter owns, it owns completely.
