Comparisons
Canto vs Otter.ai (2026)
Does Otter speak your language? It transcribes six. Canto transcribes ninety-nine.
Otter effectively invented this category, and for English-only teams it remains a solid, cheaper choice. But the conversation has moved on, literally: it's multilingual, it happens off-screen, and it deserves accuracy you can verify.
The core difference
Otter is built around transcription tuned for English. Its transcription stops at six languages, chosen one at a time before you record, and its recent product energy has gone into enterprise agents — sales, recruiting, live call coaching — rather than into broadening the core.
Canto is built for the person doing the talking: one-tap recording from watch or widget, meetings in person or online, a knowledge base in your language, and transcription accuracy that leads the public benchmarks.
Transcription quality
On independent third-party evaluations of real-world audio, Canto's transcription ranks first, at roughly two errors per hundred words. Otter publishes no accuracy figure or methodology on its own site, and its documentation lists six supported languages.

AI notes & knowledge base
Both products do live-ish transcripts, summaries, and chat. Canto goes further: custom templates, action items in your language, semantic search across everything you've ever recorded, answers that cite the exact moment of audio, and an MCP server that opens your whole library to Claude and ChatGPT rather than a read-only lookup.
Privacy & your data
Otter's sharing and auto-join defaults have caused real incidents: a transcript that captured a private post-call conversation and mailed it onward, and a hospital case the same year. It also faces a consolidated US class action, filed in 2025 and still undecided, over recording consent — and Fireflies faces biometric-privacy suits of its own. None of it is settled law, but it is the risk surface of bots that join by default. Canto keeps it boring: nothing is shared unless you share it, nothing trains models, and account deletion wipes everything.
Languages
This is the shortest section. Otter transcribes six languages — English, Spanish, French, German, Japanese and Mandarin — one at a time, picked before you hit record. Canto transcribes ninety-nine with auto-detection, ships its app in thirteen, and publishes per-language benchmark numbers you can check on our homepage.

Questions people ask
How many languages does Otter.ai support?
Six for transcription — English, Spanish, French, German, Japanese and Mandarin — per Otter's own documentation, and you choose one before recording. Canto auto-detects and transcribes 99, and handles switching mid-sentence.
Is Canto more accurate than Otter?
Otter publishes no accuracy figure or methodology on its site, so a direct comparison doesn't exist. Canto's transcription leads the independent rankings, and its per-language results are published.
Can Otter record in-person conversations?
Yes. Otter's mobile app records in person and has a home-screen widget, though the product is built bot-first. Canto is phone-and-watch-first: in-person recording is the core, with the bot for online meetings.
Which gives you more for your money?
Canto. Otter's entry plan caps you at 1,200 minutes a month and 90 minutes per meeting, and lifting those caps means stepping up to Business. Canto's Pro has no transcription cap at all, and its free plan gives you 300 minutes a month with no per-conversation limit, against Otter's 30-minute one.
