I have run both Fireflies.ai and Otter.ai on real calls, and they look almost identical at first. Both drop a bot into your Zoom, Google Meet, or Teams meeting on their own, transcribe the whole thing, label the speakers, and hand you a summary with action items afterward. On a clean one-on-one with clear audio, I would struggle to tell the two transcripts apart. The decision is not really about transcription quality. It is about what happens to the notes after the call ends, and that is where these two pull in opposite directions.
How they actually differ
Otter is built around the individual. The transcript lives in a clean, fast interface, the summary is short, and the Action Items tab surfaces follow-ups in seconds. I can open a meeting from last month, search a keyword, and land on the exact sentence where a decision got made. That is the entire job, done well, with very little weight to it.
Fireflies is built around the team and the system the team runs on. Its reason to exist is the CRM sync: notes and action items get written straight into Salesforce or HubSpot after every call, so the deal record updates itself instead of waiting on a rep to log it. On top of that sits AskFred, a chatbot you point at any past transcript to ask "what did they say about budget" and get the answer pulled from the call. Fireflies carries more, and the interface is denser and slower to move through as a result.
Pricing compared
The headline numbers sit close together. Otter Pro is about $8.33 per month billed annually, which is among the cheapest full-featured transcription plans I have used. Fireflies Pro is about $10 per user per month billed annually. So you are looking at a difference of under two dollars at the paid entry point.
What you get for that money diverges sharply. Otter's free tier gives 300 minutes a month and caps any single conversation at 30 minutes, so a long meeting gets cut off partway on free. Fireflies' free tier stores only 800 minutes total and limits AI usage to 20 summaries a month. The bigger gap is on Pro: Fireflies removes transcription caps entirely and stores up to 8,000 minutes per seat, while Otter raises your monthly minutes above the free allowance but still meters them. Then the plans split again at the top. Otter Business is $30 per user per month, a steep jump aimed at shared workspaces and admin controls. Fireflies Business is around $19 per user per month and adds unlimited storage plus video recording. One caveat on Fireflies that the per-seat price hides: AskFred and advanced summaries run on AI credits, paid plans include only a limited monthly allowance, and extras cost around $5 per 50 credits. Transcription is uncapped on Pro, the AI features are not.
Where each one wins
Otter wins on simplicity, price, and getting started. The free tier is a genuine trial, the Pro plan is cheap, and the interface stays out of your way. It holds up well on structured calls with clear audio and people taking turns. Its weak spot is messy audio: crosstalk, people talking over each other, or heavy accents produce rougher transcripts, and speaker identification needs voice training and still misattributes lines in fast group calls.
Fireflies wins on volume and on closing the loop into your sales system. The uncapped 8,000 minutes per seat means a rep on several calls a day never hits a ceiling, and the automatic CRM sync removes the logging step that quietly gets skipped at the end of a long day. AskFred earns its keep on reviewing what a prospect said across multiple calls.
Which to choose
If you are an individual or a small team taking a manageable number of structured calls, interviews, or one-on-ones, and you mostly want clean notes without setup friction, Otter is the right call and the better value. If you run a sales or customer team on Salesforce or HubSpot with heavy call volume and you need the notes to land in the CRM on their own, Fireflies is built for exactly that, and the denser interface and the credit budget are both easier to justify when the tool is load-bearing for a revenue process.
