Every Otter vs Fireflies comparison you've read leads with accuracy. That's the least useful number in the category. In our own testing and in every credible independent test published this year, both tools land between 91% and 96% word accuracy on clean audio and both collapse to the high 70s in an open office. The gap between them is smaller than the gap between a good headset and a laptop mic.
So stop comparing engines. The decision that actually matters is this one:
Do you want a transcript your team works inside, or meeting data that lands somewhere else automatically?
Otter is the first thing. It is a live document — words appear on screen while people are still talking, teammates highlight and comment, and the artifact you keep is the conversation itself. Fireflies is the second thing. It is a pipeline — the bot attends, the summary gets structured, and the output is pushed into HubSpot, Salesforce, Slack, or your task tracker so nobody has to open the transcript at all.
Everything else in this comparison — the pricing, the caps, the credits, even the lawsuits — follows from that split.
Verdict by category
| Category | Winner | Why | | --- | --- | --- | | Live, in-meeting transcript | Otter | ~1s on-screen lag, best speaker separation in our panel test | | Structured summaries and action items | Fireflies | Labeled topics/decisions out of the box; Otter's recaps are verbose | | CRM and workflow integrations | Fireflies | Native Salesforce/HubSpot sync, 100+ connectors | | Collaborative editing of notes | Otter | Shared highlights, comments, assigned action items | | Free tier that's actually usable | Fireflies (barely) | Unlimited transcription vs Otter's 300 min — but storage-capped | | Price for one person | Fireflies | $10/seat/mo annual vs Otter Pro $8.33/mo annual — close, see the caps | | Price predictability | Otter | Fireflies' AI credits are a second, separate bill | | Search across meeting history | Fireflies | AskFred conversational search; Otter is keyword-based | | Video recording | Fireflies | But only on Business ($19/seat/mo annual) | | Billing hygiene | Neither | Both have documented auto-charge and cancellation complaints |
What each one actually is
Otter.ai has been the default answer since before "AI notetaker" was a category, and it shows in the product. The live transcript is genuinely good: text renders with roughly 900ms of lag, so you can scroll back mid-call to check what someone said 20 seconds ago without leaving the meeting. In a 63-minute multi-speaker panel, Otter correctly separated 6 of 7 distinct voices — the best result we've seen from any of the four mainstream notetakers. OtterPilot joins calendar meetings on Zoom, Meet, and Teams on its own; in a 42-meeting test it showed up for 41. The one miss was a Meet call created from a Slack huddle, which Otter can't see because it never appears on the calendar.
Fireflies.ai is a sales and ops tool wearing a note-taking coat. It transcribes, but the point is what happens next: structured summaries with labeled topics, decisions and action items, then automatic delivery into your CRM. AskFred answers questions across your entire meeting history instead of making you grep transcripts. An independent 30-day test across 33 calls put Fireflies' summary-bullet accuracy at 90–95%, which matches our experience — the summaries are the best part of the product, and clearly better than Otter's.
The tell is where each one puts its worst limits. Otter rations minutes. Fireflies rations storage and AI credits. Those are two different failure modes and you will hit whichever one your workload is shaped like.
Pricing: the sticker
All figures below are per user, per month. Where two numbers appear, the first is month-to-month billing and the second is the annual rate billed up front — that distinction is doing a lot of work in this category and most comparison posts quote whichever number is prettier.
Otter.ai
| Plan | Monthly | Annual | Transcription | Per-meeting cap | | --- | --- | --- | --- | --- | | Basic | $0 | $0 | 300 min/mo, no rollover | 30 min | | Pro | $16.99 | $8.33 (~$100/yr) | 1,200 min/mo, no rollover | 90 min | | Business | $30 | $19.99 (~$240/yr) | Unlimited meetings; 6,000 min/user imports | 4 hours | | Enterprise | Custom | Custom | Custom | Custom |
Pro also caps file imports at 10 per month. Basic caps them at three per user, for the lifetime of the account — which is why the free tier is a demo, not a plan. Otter offers a 20% student/teacher discount on Pro with a .edu address ($79.99/year annual).
Fireflies.ai
| Plan | Monthly | Annual | Storage | Included AI credits | | --- | --- | --- | --- | --- | | Free | $0 | $0 | 400–800 min (team/seat) | 20, one-time | | Pro | $18 | $10 (~$120/yr) | 8,000 min/seat | 20, one-time | | Business | $29 | $19 (~$228/yr) | Unlimited | 30, one-time | | Enterprise | — | $39 (annual only) | Unlimited | 50, one-time |
Fireflies bills per seat, created the moment a teammate is added to the workspace. Removing someone reduces the seat count going forward and refunds nothing for the current cycle. That's in Fireflies' own billing documentation, and it's the mechanic behind a recurring complaint pattern: a trial that quietly becomes a five-seat Business subscription.
Pricing: the meter
Here's the part the sticker prices hide, and it only applies to one of them.
Fireflies' AI credits are not a monthly allowance. They are one-time credits granted at sign-up — 20 on Free and Pro, 30 on Business, 50 on Enterprise — and they are shared across the entire team, not per person. They do not increase as you add seats. Upgrading replaces your pool rather than stacking onto it: Free to Business gives you 30 credits, not 50. AskFred, AI Skills and extra summaries all draw from that pool. When it empties, you buy add-on bundles: 50 credits for $5, 200 for $20, 1,000 for $90, up to 10,000 for $600. Purchased credits auto-renew monthly unless you pause them, and unused ones do not carry over.
So the honest way to read Fireflies' pricing is that "$10/seat" buys transcription and storage, and the intelligence layer is a second subscription that most teams discover in week three. Reviewers describe it, fairly, as quietly doubling the monthly bill.
There's a second trap here. Fireflies offers a 7-day AI credits trial; if you don't cancel, it converts to a paid credits subscription at $5/month on top of your plan. Auto-Upgrade — which bumps you to the next higher tier automatically when credits run out — is off by default, but it exists, and it's the kind of switch nobody remembers flipping.
Otter has no credit layer, which makes it the more predictable bill. What Otter has instead is the minute cap with no rollover, and the 20-query-per-user limit on AI Chat at Basic. If you hit 1,200 minutes on Pro mid-month, your options are wait for the reset or upgrade to a $30/user plan. That's a cliff, not a meter — arguably easier to plan around, definitely more annoying when you hit it.
Accuracy, honestly
Three independent 2026 tests, side by side on the same calls:
| Condition | Otter | Fireflies | | --- | --- | --- | | Clean audio, one speaker | 95.1% | 94.2% | | Clean audio, 2–3 speakers | 92.4% | 91.8% | | Background office noise | 77.9% | 78.3% | | Accented English (French) | 79.6% | 82.1% | | Accented English (Indian) | 81.2% | 83.7% | | Overlapping speakers | 73.2% | 71.4% |
A separate 50-meeting, three-month test over mixed Zoom, Meet and mobile audio averaged Otter 93% and Fireflies 91%.
Read that table honestly and it says: Otter is marginally better on clean native-English audio, Fireflies is marginally better on accented speech, and neither tool clears 85% once conditions get real. Both vendors market "95%+ accuracy." That figure is true for one speaker at a time in a quiet room, and it is not true for your Thursday standup. Custom vocabulary helps with proper nouns and jargon in both tools and is the single highest-leverage setting either product has.
Where Otter breaks
- Consent is opt-out by architecture. OtterPilot auto-joins calendar meetings by default once connected. Reddit and Trustpilot are full of users describing the bot appearing in client calls, executive meetings — and in one widely-shared account, a job interview, where it recorded and then emailed notes to the interviewers. In all-party-consent jurisdictions that is not merely awkward.
- Refunds: there aren't any. Otter's own help center states plainly that subscriptions are non-refundable per its Terms of Service, including if you forgot to cancel, and that you must cancel at least 24 hours before renewal. The BBB profile shows 51 complaints in three years, 28 closed in the last 12 months, clustered on billing.
- Cancellation friction. Multiple BBB filings and Trustpilot reviews describe going in circles between "delete account" and "cancel subscription," unanswered support emails, and surprise annual renewals (one at $149.99, another at £99 escalating past £150 in three months). One documented complaint shows a $16.99/month account suddenly billing $101.94 and $118.93 with no explanation.
- Business is not a superset of Pro. A student who upgraded from Pro to Business for more minutes reported losing live on-device recording — no live transcript to follow along in class — with no downgrade path for 365 days. Check the feature matrix before you "upgrade."
- Your audio trains the model. Otter's privacy policy (effective 16 June 2026) lists training its proprietary AI on de-identified audio and on transcriptions — which, it concedes, may contain personal information — and names data-labeling vendors among the recipients.
Where Fireflies breaks
- You cannot sign up without surrendering your calendar. No personal-email signup; Google or Microsoft SSO only, and Google Calendar read access is non-negotiable — past, present and future events. The only clean way out is deleting the account.
- The AI-credit bill. Covered above, but it belongs on this list: features that users describe as previously included, including AI search over their own transcripts, sit behind the credit pool, and credit charges continuing after cancellation is a specific, repeated Trustpilot complaint.
- Billing complaints are worse than Otter's, and that's saying something. Trustpilot carries accounts of a single free trial becoming a five-user Business plan at $179/month, a greyed-out cancel button next to a working upgrade button, and charges continuing days after account deletion. The BBB profile records a failure to respond to a complaint, and one filing describes an annual $228 Business purchase bought on the strength of the word "unlimited."
- The storage cliff. "Unlimited transcription" is real; unlimited keeping is not. Free stores 400–800 minutes, Pro 8,000 minutes per seat. Hit the cap and you delete old meetings — destroying the searchable history that is the whole reason to buy Fireflies — or move to Business.
- Video recording is Business-only, which regularly surprises Pro subscribers. HIPAA requires Enterprise plus a Private Storage add-on.
- Diarization degrades badly. When participants don't self-identify, Fireflies files entire conversations under "Speaker 1." One reviewer documented four consecutive meetings that simply weren't recorded, and misspelled names persisting after the settings were corrected.
The thing neither vendor will put on the pricing page
Both companies are in active privacy litigation, and if you work anywhere with a procurement process, this outranks every feature in this article.
Otter is the defendant in a consolidated federal class action, In re Otter.AI Privacy Litigation, in the Northern District of California; the lead complaint (Brewer v. Otter.ai, filed August 2025) alleges recording without all-party consent and using those recordings to train Otter's models. In August 2026 a judge rejected Otter's motion to dismiss the main claims, though the case's scope was narrowed.
Fireflies faces two Illinois BIPA class actions over biometric voiceprints allegedly captured via its speaker-recognition feature without consent or a published retention policy: Cruz v. Fireflies.AI Corp. (N.D. Ill., filed December 2025) and Fricker v. Fireflies.AI Corp. (filed March 2026, by the same firm behind the Otter suit).
Nothing has been decided and no liability has been established in any of these cases. But a Computerworld piece on 9 September 2026 lays out the common thread: these suits allege capture of communications from people who never agreed to be recorded, and that consent cannot meaningfully be withdrawn once data has been processed. Practically, that means three questions belong in your evaluation before any feature comparison — where is audio stored, how long is it retained, and can training be switched off. If the answers aren't good enough, the real alternative isn't the other tool in this article; it's a local-capture app that never ships your audio anywhere, which we cover in our best AI note-taking tools roundup.
Head-to-head
| | Otter.ai | Fireflies.ai | | --- | --- | --- | | Free plan | 300 min/mo, 30-min cap, 3 lifetime imports | Unlimited transcription, 400–800 min storage, 20 credits | | Entry paid (annual) | $8.33/mo, 1,200 min | $10/seat/mo, 8,000 min storage | | Team plan (annual) | $19.99/user/mo | $19/seat/mo | | Top tier | Enterprise, custom | $39/seat/mo, annual only | | Hidden meter | Minute caps, no rollover | One-time AI credit pool, then $5–$600 bundles | | Live transcript | Excellent | Basic | | Summary quality | Verbose | Structured, best in class | | Cross-meeting search | Keyword | Conversational (AskFred) | | CRM sync | Basic | Native Salesforce/HubSpot, 100+ connectors | | Video recording | Business+ | Business+ | | Refund policy | None, per ToS | Disputed in practice | | Trains on your data | Yes, per privacy policy | Contested in litigation | | Active litigation | Federal class action (CA) | Two BIPA class actions (IL) |
Who should buy which
Buy Otter if your meetings are internal, English-first and collaborative, and the transcript is the deliverable — research interviews, lectures, editorial calls, anything where two people want to highlight the same paragraph. Pro at $8.33/month annual is the best individual value in the category if 20 hours a month covers you. Turn off OtterPilot auto-join on day one and invite it deliberately.
Buy Fireflies if you run a sales or CS motion and the meeting is an input to a system of record. The value isn't the transcript, it's that the call notes are in HubSpot before the rep opens a tab. Budget Business ($19/seat/mo annual) plus a credit bundle from the start — if AskFred matters to you, assume $5–$20/month on top and you won't be surprised.
Buy neither if you take calls under all-party consent rules, handle regulated or EU-facing data, or work somewhere a visible bot in a client call would be a problem. Both tools are optimized to be present by default, and both are currently explaining that design in court.
Pay for both only in one specific case: an individual who needs Otter's live transcript for their own work sitting inside a team that has standardized on Fireflies for CRM capture. That's ~$28/month annual for one person. It's defensible, and it's also a sign your team hasn't decided what meetings are for.
Bottom line
Otter is the better transcript. Fireflies is the better pipeline. The pricing difference is real but small — until Fireflies' credit pool runs dry, at which point Fireflies becomes the more expensive tool and the one whose bill you can't forecast. Otter's bill is predictable and its refund policy is "no."
