Fireflies.ai vs Otter.ai
Fireflies.ai and Otter.ai both send a bot into your calls to record, transcribe and summarize, then keep a searchable archive. Reviewers put transcription accuracy for both at roughly 90 to 95 percent with clear audio, so accuracy is not the separator. Fireflies is broader, with 100+ languages, CRM sync and conversation analytics aimed at sales teams. Otter is narrower but mature, with live captions and strong search, and it transcribes only six languages. Both carry privacy questions worth checking before rollout.

Verdict
Pick Fireflies.ai if meetings feed a sales or customer pipeline. Its CRM sync, integration catalogue and talk-time, sentiment and topic analytics make recorded calls useful for coaching and follow-up, and it transcribes in more than 100 languages, though only one per meeting. The tradeoffs are storage caps that reviewers report hitting within weeks, AI credits that can run out mid-month, support that leans on automated responses, and a visible bot some participants object to. One industry source references a 2026 privacy action involving the company, which is worth verifying.
Pick Otter.ai if your team works in English and wants a dependable meeting archive with live captions, collaborative editing and search that reviewers rate among its strongest features. Its free tier suits individuals with a few meetings a week. The tradeoffs are limited language support and, more importantly, an unresolved federal class action over recording participants who did not consent, alongside user complaints about the bot joining uninvited and transcripts being emailed to external attendees.
For external calls in all-party-consent jurisdictions, check the current legal status of both vendors and announce the recorder yourself, whichever you choose.
