Frequently asked questions

Is Read.ai better than Otter? ⌄
It depends on what you need. Read.ai adds meeting analytics like engagement, sentiment, and talk-time, and summarizes email and messages, which Otter does not. Otter has more accurate live transcription and captions, is simpler, and is cheaper, and it has higher user ratings. For analytics, Read.ai; for accurate, no-fuss notes, Otter.
Is Read.ai free? ⌄
Read.ai has a free plan limited to 5 meetings per month, with transcripts, summaries, search, and 20+ languages. Unlimited transcripts require the Pro plan at about $15 per user per month billed annually.
Which is the best free AI meeting assistant of the three? ⌄
Fireflies, by a wide margin. Its free plan includes unlimited transcription, while Read.ai caps the free plan at 5 meetings a month and Otter at 300 minutes a month.
What makes Read.ai different? ⌄
Read.ai focuses on meeting analytics: it measures engagement, sentiment, and talk-time, offers speaker coaching, and summarizes not just meetings but email and messages. Its “Ask Read” AI search spans all of those channels, which neither Otter nor Fireflies does.
Are there privacy concerns with Read.ai? ⌄
Some users have reported the assistant joining meetings without clear consent, along with concerns about data access and account management, and Read.ai’s Trustpilot score is notably lower than its G2 score. If consent and privacy controls matter, review Read.ai’s settings carefully, or consider Otter or Fireflies, which have higher user ratings.
