Most comparisons of these two tools argue about transcription accuracy. That is no longer the interesting question — both are good enough, and neither will meaningfully change your week. The question that should decide which AI notetaker you buy in 2026 is what happens when a bot joins a call and one of the people on it never agreed to be recorded.
On 13 August 2026, a federal judge in California allowed the central claims in the consolidated Otter privacy case to proceed past a motion to dismiss — the federal wiretap claim, the California privacy claim and the Illinois biometric claim all survived. No court has found Otter did anything unlawful; that is not what surviving a motion to dismiss means. But it does mean the case gets to the evidence stage, and it means the “the bot is visible, so everyone consented” defence is now something a court is actually examining rather than something vendors can assert in a help article.
So this comparison covers the money first, then the part your accountant cannot help you with. Pricing checked 20 August 2026.
The two products meter completely different things
This is the single most useful thing to understand before you compare prices, and almost every article gets it wrong by lining the two up in a table as if they sold the same unit.
Otter meters minutes. You get a monthly transcription allowance. When it runs out, recording stops. There is no top-up and no rollover.
Fireflies meters storage and AI credits. Transcription is unlimited on every tier, including free. What is capped is how many minutes of meeting content your account keeps, and how many times you can use the AI features — AskFred, advanced summaries, highlights — before they pause for the month.
| Tier | Otter (per user) | Fireflies (per seat) |
|---|---|---|
| Free | 300 min/month, 30 min per meeting, 3 lifetime file imports | Unlimited transcription, but ~400 min of storage for the whole team, 20 AI credits, no transcript download |
| Entry paid | Pro — $16.99/mo, or $8.33/mo billed annually. 1,200 min/month, 90 min per meeting, 10 file imports/month | Pro — $18/mo, or $10/mo billed annually. 8,000 min storage, downloads, ~20 AI credits/month |
| Team | Business — $30/mo, or $19.99/mo annually. Unlimited in-app meeting minutes, 4 hr per meeting, imports still capped | Business — $29/mo, or $19/mo annually. Unlimited storage, ~30 AI credits, CRM sync, conversation intelligence |
| Top tier | Enterprise — custom quote; SSO, SCIM, API | Enterprise — $39/seat, annual only; HIPAA, SSO, retention controls |
Two things worth flagging in that table. Otter’s headline prices on its own site are the annual rates — pay monthly and Pro roughly doubles. And Otter’s Pro minute allowance was cut sharply during 2025 without the price moving, which is why older reviews quote a much larger number. Sources also disagree on the Fireflies free storage figure (400 or 800 minutes), so check the live page rather than trusting either number here.
Choosing an AI notetaker on cost alone
If your decision is purely financial, it comes down to one question: do you record a lot, or do you keep a lot?
- Heavy recorder, light archive. Four hours of calls a day puts you past Otter Pro’s 1,200 minutes in about ten working days. Fireflies never stops transcribing, so it wins outright here.
- Long meetings. Otter Pro caps a single conversation at 90 minutes. If your workshops or client sessions routinely run two hours, Pro is the wrong plan and you are looking at Business.
- Lots of uploaded recordings. Otter Pro allows only ten file imports a month, and free allows three in the account’s entire lifetime. For podcasters and interviewers this is the wall you hit first.
- Heavy AI use. Fireflies credits are the hidden meter. Ask a lot of questions of your transcripts and you will buy more credits, which is a cost that never appears on a comparison page.
For a solo operator, Fireflies Pro on annual billing is the cheaper entry point and the more forgiving one. For a team where somebody needs to read everyone else’s notes, both jump to roughly $19–20 per seat annually — at which point the deciding factor stops being price. This is the same pattern we found across the category in free vs paid AI tools: the free tier is a demo, the entry tier is the real product, and the team tier is where the actual margin lives.
The consent problem belongs to you, not the vendor
Here is what makes this category different from every other AI tool you buy.
The consolidated case against Otter — In re Otter.AI Privacy Litigation, N.D. Cal., which bundles four suits filed in August and September 2025 — was brought largely by people who were never Otter customers. They sat in meetings somebody else brought the bot into. The complaint alleges the assistant auto-joined calls, captured audio and speaker voiceprints, and that recordings were used to improve the product under default settings.
A separate suit, Cruz v. Fireflies.AI Corp., filed in Illinois in December 2025, targets Fireflies under the Illinois biometric privacy statute over speaker-recognition voiceprints. Different theory, same structural problem. This is not a one-vendor story.
The part that matters commercially: both vendors’ terms push the responsibility for obtaining consent onto the account holder. That is you. If you run a bot into a call with someone in a state or country that requires all parties to agree to a recording, the exposure is yours regardless of which logo is on the bot. Illinois biometric claims carry statutory damages per violation, and California’s privacy statute does the same, which is why the numbers in these cases get large quickly.
| Situation | Sensible practice |
|---|---|
| Internal team standups | Low risk — but tell people once, in writing, that it is on by default |
| Client and prospect calls | Ask before the bot joins, not after. Put it in the calendar invite |
| Interviews, HR, medical, legal, or anything with a minor | Explicit recorded consent, or don’t record |
| Calls crossing state or national borders | Assume the strictest rule on the call applies |
| Anything you would not want read back in a deposition | Turn auto-join off entirely |
Two settings changes take five minutes and remove most of the risk: switch off calendar auto-join so the bot only records when you deliberately start it, and turn off the option that lets your transcripts be used to improve the vendor’s models. Both tools have that second toggle; on at least one of them the default has historically been the permissive one.
Feature differences that actually decide it
| If you need… | Pick |
|---|---|
| CRM sync and sales conversation analytics | Fireflies (Business tier) |
| Live captions and in-room recording on a phone | Otter — the mobile capture is its oldest strength |
| Video recording alongside the transcript | Fireflies (paid tiers, with per-meeting length caps) |
| Querying months of past meetings in natural language | Fireflies, if you accept the credit meter |
| Transcribing lectures, interviews and pre-recorded audio | Neither on entry tiers — the import caps bite. Use a per-minute transcription service |

Before you pay for either one
Check what you already own. Zoom, Google Meet and Microsoft Teams all ship their own meeting summaries now, bundled into plans many businesses already pay for — the details vary by platform and tier, and Microsoft’s is generally tied to a separate paid licence. If your team lives on one platform, the built-in option costs nothing extra, keeps the data inside a vendor you have already vetted, and avoids adding a third-party bot to the call at all.
A dedicated AI notetaker earns its money when you work across several meeting platforms, need transcripts searchable in one place regardless of where the call happened, or need CRM automation the native tools do not do. If none of those apply, you are paying for a duplicate. That is the same audit we walk through in AI tools that replace expensive software and cutting business costs with AI.
Real limitations of both
- Summaries are confident about things that did not happen. Action items get attributed to the wrong person, and tentative remarks get recorded as decisions. Skim the summary against the transcript before forwarding it.
- Accents, crosstalk and poor microphones still break speaker labelling. Vendor accuracy figures are measured on clean audio.
- The bot changes the meeting. People say less, and say it more carefully, when a recorder is visibly present. That cost never shows up in a pricing table.
- Limits move. Otter’s Pro minutes were cut mid-life; Fireflies adjusts credit allowances. Prefer monthly billing until you have watched a vendor’s limits hold for a while.
- Both are cloud-based by design. Every recording leaves your machine. On-device transcription is the only architecture that avoids the legal questions above entirely, and neither of these is that.
The verdict
For solo operators and small teams: Fireflies Pro on annual billing. Unlimited transcription means you never lose a call to a meter, and the storage cap is generous enough that you will forget it exists. See also our picks in AI tools for solopreneurs.
For people who mostly record in the room rather than on a call — journalists, researchers, consultants taking notes face to face: Otter, on Business if the 90-minute cap or the import limit would bite.
For anyone selling into regulated industries, or working across borders: fix your consent process before you pick a tool. Then either works, and neither saves you if the process is wrong. Broader stack recommendations are in best AI tools for small business owners, and if you are wiring notes into other systems, start with automating work with AI tools.
Frequently asked questions
Which is cheaper, Otter or Fireflies?
Fireflies, at the individual level. Its entry plan is about $10 per seat per month on annual billing versus Otter Pro’s $8.33 — slightly more on paper, but with unlimited transcription instead of a 1,200-minute cap. At team level both land around $19–20 per seat annually.
Is it legal to use an AI notetaker without telling people?
In many places, no. Several US states and many countries require every participant to consent before a conversation is recorded. Both vendors place that obligation on the account holder in their terms, so the risk sits with whoever brought the bot into the call. This is general information, not legal advice — check the rules where your participants are.
Did Otter.ai lose its lawsuit?
No. In August 2026 a judge dismissed some claims but allowed the federal wiretap, California privacy and Illinois biometric claims to proceed. That is a ruling about whether the case can continue, not a finding that Otter broke the law. The case is ongoing.
Can I use the free plans for real work?
Barely. Otter’s free tier stops at 300 minutes a month and three lifetime file imports. Fireflies transcribes unlimited meetings but stores only a few hundred minutes across the whole team and blocks transcript downloads. Both are evaluation tiers.
Do I even need an AI notetaker if I use Zoom or Google Meet?
Possibly not. Both platforms include their own meeting summaries on paid plans. A dedicated tool is worth it when you work across multiple platforms, need one searchable archive, or want CRM automation — otherwise you are paying twice.
Do these tools train on my meetings?
Both offer a setting to opt out of having your content used to improve their models, and the default has not always been the private one. Check it on day one, at the workspace level rather than per user.
