Otter.ai vs Fireflies.ai: Our Verdict
Two AI notetakers that both join your Zoom calls, transcribe them, and hand back a summary. We ran them side by side to decide which one working teams should actually pay for in 2026.
Fireflies takes the recommendation for most working teams on the strength of 100+ language coverage, deeper CRM integrations, and unlimited transcription on every paid tier. Otter remains the pick for English-first buyers who want slide capture and a live in-meeting voice agent, but a six-language ceiling, hard minute caps, and an unresolved federal consent lawsuit make it the harder recommendation in 2026.
Otter and Fireflies answer the same brief: join a scheduled Zoom, Google Meet, or Microsoft Teams call, transcribe it in real time, and hand back a summary with action items. On paper the two products look interchangeable. In use, they aren't.
We tested both on the same production meeting load through July and August 2026, priced each against the paid tier a working professional would actually buy, and read the current terms and legal filings for both. The rounds below name a winner and state the procedure we used to decide it.
Fireflies transcribes in 100+ languages with automatic detection, and the vendor reports 99% accuracy for English and 95% for other languages. Otter's own help center lists exactly six supported languages, English, Spanish, French, German, Japanese, and Chinese (Simplified), with German and Simplified Chinese still marked beta, and Otter cannot transcribe more than one language at a time in the same recording. For any team with non-English calls, this round isn't close.
How we tested itWe listed every language each vendor claims to transcribe on its current product and support pages, then ran a test recording in each of four non-English languages (Spanish, German, Portuguese, and Hindi) to confirm the claim was real rather than marketing.
Every Fireflies paid tier includes unlimited transcription; what you buy is storage, video, and AI credits. Otter's Pro tier is capped at 1,200 transcription minutes a month with a 90-minute per-conversation ceiling, and once you hit the cap Otter simply stops transcribing until the next billing cycle. Pro pricing is close at the door ($10/seat/month annual for Fireflies vs $8.33 for Otter), but Otter's Pro was quietly cut from 6,000 to 1,200 minutes without a price change, and heavy users get pushed to Business at $19.99/seat/month annual to remove the cap.
How we tested itWe priced each vendor's Free, Pro, and Business tiers at their current annual and monthly rates and mapped the hard limits (transcription minutes, storage, file imports, per-meeting length) that a normal week of four to six meetings would actually hit.
Fireflies' Pro plan unlocks unlimited integrations, including native Salesforce, HubSpot, Zoho, and Pipedrive connectors, and the Business plan adds Integration Rules so only the meetings you designate log to the CRM. Otter's structured CRM write-back, including custom Salesforce field mapping and BANT/MEDDIC extraction, is gated behind the Enterprise tier. That's the deepest workflow feature set on offer, but also the most expensive way to buy it.
How we tested itWe connected each tool to a Salesforce sandbox and a HubSpot account, pushed the same meeting through both, and checked which fields were written, whether integration rules could scope the sync, and how many third-party destinations each vendor exposed on its paid plans.
Otter's automatic slide capture pairs the shared visuals with the transcript in a single searchable record, and Otter AI Chat answered our cross-meeting question with source attribution and no monthly credit cap. Fireflies' AskFred can pull context from email and Slack alongside meetings, which Otter cannot, but its advanced summaries, action-item extraction, and AskFred queries draw on a monthly AI credit pool (20 on Pro, 30 on Business, 50 on Enterprise) that heavy users exhaust well before the month ends.
How we tested itWe ran the same three meetings through each tool with slides shared, then asked each vendor's AI assistant a question that required context from a call three weeks earlier, and checked whether the tool captured slide content alongside the transcript.
Otter is the named defendant in a consolidated federal class action, In re Otter.AI Privacy Litigation, No. 5:25-cv-06911 in the Northern District of California, over how its Notetaker bot records people who never consented, and Otter still trains its AI on customer conversations by default using de-identified audio and transcripts. Fireflies states that customer meeting data is not used to train third-party models. For any team recording external participants in an all-party consent state, this round should carry disproportionate weight.
How we tested itWe read each vendor's current terms and privacy documentation and searched federal court dockets for active litigation naming either product.
Where the verdict turned
Otter and Fireflies both join Zoom, Google Meet, and Microsoft Teams calls, transcribe in real time, and generate summaries. The resemblance ends at the transcript. Every round we ran turned on how each vendor handled the work that happens after, and around, the transcript itself.
Fireflies took language coverage decisively. Transcription works in 100+ languages with automatic detection, and accuracy reaches 99% for English and 95% for other languages. Otter’s own documentation confines it to a much shorter list: English, Spanish, French, German, Japanese, and Chinese (Simplified), with German and Chinese (Simplified) still in beta, and only one language transcribed at a time in the same recording. For any team with a non-English speaker on the call, that’s a product limit, not a preference.
The pricing round went the same way on the merits. Fireflies runs four plans: Free ($0), Pro ($10/seat/month billed annually), Business ($19/seat/month billed annually), and Enterprise ($39/seat/month, annual only), and all four include unlimited transcription and unlimited AI summaries. Otter’s Pro plan runs $8.33/user/month annual or $16.99 monthly, and Otter quietly cut Pro from 6,000 to 1,200 transcription minutes without lowering the price, so heavy users burn through the allowance in under two weeks. When the cap is hit, Otter doesn’t offer pay-as-you-go overage charges on capped plans. Hit your monthly limit on Basic or Pro and the service stops working entirely until your plan resets or you upgrade.
Where Otter still wins
Otter took the in-meeting round on the strength of features Fireflies hasn’t matched. Otter AI Chat surfaces context across months or years of meetings with source attribution, and isn’t throttled by a monthly credit cap or lookback window. Automatic slide capture pairs visual context with the transcript in the same searchable record. Fireflies’ equivalent is powerful but metered: the AI credits system governs access to AI summaries, action items, AskFred, and meeting highlights, with each plan including a shared credit pool (Free: 20, Pro: 20, Business: 30, Enterprise: 50), plus add-on credits available in bundles that auto-renew monthly unless paused. Hit the cap and those features pause until the next month or until you buy more at roughly $0.10 each. Heavy users report paying $15–50/month above the sticker price in overages.
Otter has also closed the gap on automation. It now ships five named AI Agents, covering Sales, Education, Media, SDR, and Recruiting, plus AI Meeting Workflows and a Gmail connector added in May 2026. That’s real progress, but Fireflies is still ahead on the breadth of built-in workflows, and on the one thing Otter AI Chat cannot do: AskFred’s ability to pull context from email and Slack alongside your meetings.
The consent question
The most important non-feature difference between these products is legal. Otter is the named defendant in a consolidated federal class action over how its bot records people who never agreed to be recorded. The case is In re Otter.AI Privacy Litigation, in the Northern District of California. That consent question, not transcription quality, is the biggest reason buyers are leaving Otter in 2026. The suit alleges Otter “does not obtain prior consent, express or otherwise” from people in a meeting before its Notetaker records, transcribes, and learns the contents of their conversation. Layered on top: Otter still trains its AI on your data by default, and that policy is now the subject of a federal lawsuit.
For an individual using Otter to take notes on internal meetings, this is a manageable concern. For a sales team recording external prospects in California, Washington, Florida, or any other all-party consent state, it’s a live risk that outlives any particular ruling.
Who should buy which
Choose Fireflies if you run meetings in more than one language, if you want CRM write-back at the mid tier rather than at Enterprise, or if the pricing model that matters to you is “unlimited transcription with a metered AI layer” rather than “metered transcription with unlimited AI credits.” It’s the safer starting point for most working teams, and it’s the pick for anyone with sales or customer success calls that leave the company.
Choose Otter if your meetings are almost entirely in English, if slide capture is a real part of how you review meetings later, and if you want a live AI meeting agent that speaks in the call rather than only after it. Individual professionals and academic users are Otter’s strongest fit; sales organizations should read the consent complaint before signing an annual seat count.
Neither tool ends the category. Asked to name one for the working professional buying today, we recommend Fireflies.
Questions readers ask
Is Fireflies actually cheaper than Otter? At the door, Otter Pro is $8.33/seat/month annual to Fireflies Pro’s $10, so Otter is slightly cheaper on sticker. Once you factor in caps, Fireflies is cheaper for anyone who runs more than about 20 hours of meetings a month, because Otter Pro stops transcribing at 1,200 minutes and Fireflies doesn’t.
Does either tool train its AI on my meetings? Otter trains on de-identified customer audio and transcripts by default. Fireflies states that customer meeting data is not used to train third-party models. If model training on your calls is a dealbreaker, read this field carefully on both vendors’ current policies.
Can I use either one for HIPAA-covered meetings? Both offer HIPAA coverage, but at different tiers. Fireflies bundles HIPAA into Enterprise pricing, while Otter treats it as an Enterprise add-on. For healthcare and regulated industries, budget accordingly.
Do I still need one of these if my meetings are already recorded in Zoom or Teams? Yes, if the point is a structured summary, action items, searchable transcripts across months of calls, and a push to your CRM or task tool. A raw cloud recording isn’t the same product.
