Whisper vs Otter and Fireflies: Free vs Paid Transcription

Otter gives you 300 free minutes a month but only three file imports ever. Fireflies offers unlimited free transcription with capped storage. Whisper running on your own machine gives you unlimited everything for free, and your audio never leaves the building. Which matters most depends on whether your recordings are confidential.

Key takeaways

• Otter's 3 file imports are lifetime, not monthly. After three uploads you cannot import again without paying.
• Fireflies has the most generous free tier: unlimited transcription, though storage is capped at 400 minutes per team.
• Rev's free tier is 45 minutes a month, English only. Its human transcription at $1.99/minute remains the accuracy leader.
• Whisper is MIT licensed for code and weights, so transcripts are unrestricted commercially and unlimited in volume.
• For confidential recordings, local transcription removes a compliance question rather than answering it.

What each actually costs

Verified on vendor pricing pages in September 2026:

Otter's Business tier is $30 per user monthly ($24 annually). Fireflies Business is $29 ($19 annually). Descript runs to $24 and $50 on higher tiers. Rev Pro is $47.99 annually with 10,000 verbatim minutes.

The Otter detail people miss: its free plan advertises 300 monthly transcription minutes, which sounds generous. But file imports are capped at three for the lifetime of the account. If your workflow is uploading existing recordings rather than having Otter join live meetings, the free tier is effectively a three-use trial.

Fireflies is the strongest free tier here if you want cloud convenience. Unlimited transcription in 100+ languages, real-time notes, meeting search and its AskFred assistant, with storage rather than minutes as the binding limit.

Where the paid services genuinely win

Being fair to them, several things local transcription does not do:

They join your meetings. Otter and Fireflies connect to Zoom, Google Meet and Teams, attend automatically, and produce a transcript without you recording anything. That is a real workflow advantage, not a gimmick.

Zero setup. No installs, no models to download, no hardware questions.

Sync and search across everything. Every transcript in one searchable place, on every device.

Team features. Shared workspaces, speaker vocabularies, integrations with Salesforce, HubSpot and Zapier on paid Otter tiers.

Human accuracy when it matters. Rev's $1.99-per-minute human transcription delivers 99%+ accuracy within 12 hours. On difficult audio (crosstalk, heavy accents, poor microphones) no AI tool matches it, and Rev's Legal Premium at $2.50 per page claims 99.7%+.

Analysis across many transcripts. This is the one gap local Whisper cannot close by adding hardware. Whisper gives you a text file per recording; it has no view across fifty of them. Speak AI is built for that job instead, tagging themes, sentiment and recurring keywords across a whole corpus, which is what user researchers and anyone running repeated customer interviews actually need. If you transcribe to find patterns rather than to read one transcript, that is a different product category and worth knowing exists.

Where local wins

Cost and volume. Unlimited, free, forever. If you transcribe more than a few hours monthly, every paid tier becomes expensive and every free tier runs out.

Privacy, which is the strongest argument. Whisper, whisper.cpp, faster-whisper, Buzz and meetily all run entirely on your machine. Audio is never uploaded.

For client calls, HR conversations, medical or legal discussions, investor updates or anything under NDA, cloud transcription is a compliance question you have to answer. Local removes the question. meetily is built around exactly this, using Ollama for local summarisation with no external calls at all.

Commercial rights. Whisper is MIT licensed for both code and model weights, so your transcripts carry no usage restrictions. That is not universal in free AI tooling.

No vendor risk. Services change pricing, get acquired, or shut down. A model on your drive does not.

Accuracy, honestly

Whisper large-v3 is competitive with commercial services on clean audio. The turbo model offers most of that accuracy at roughly eight times the speed.

Where it falls behind: heavy background noise, overlapping speakers, strong accents and poor recording equipment. Commercial services tune for meeting audio specifically, and Rev's human option handles what no model manages.

Whisper also has a specific gap worth knowing: openai/whisper does not do speaker diarization. It produces one undifferentiated transcript. If you need who-said-what, use Buzz (which has speaker identification) or WhisperX (best quality, using pyannote). Note that meetily's free edition does not do diarization either, as that is marked for its PRO version, contrary to several roundups.

Otter and Fireflies both do speaker identification out of the box.

Setup: the real difference

Otter, Fireflies, Rev, Descript: sign in, connect your calendar, done.

Whisper locally: easier than most guides suggest. Buzz is MIT licensed with installers for Apple Silicon Macs and Windows, giving you drag-and-drop transcription, live capture, speaker identification and SRT export with no terminal. Two friction points: Intel Mac support ended, and the Windows installer is unsigned so you click through a SmartScreen warning.

For meetings specifically, meetily ships a Mac DMG and Windows installer and captures microphone plus system audio simultaneously, so it records both sides of a call.

Which should you choose?

Choose local Whisper via Buzz if your recordings are confidential, you transcribe regularly, or you want unlimited free transcription with commercial rights.

Choose Fireflies free if you want cloud convenience at no cost, your meetings are not sensitive, and you want the assistant to join calls automatically.

Choose Otter paid if you need meeting-bot convenience with team features and CRM integrations, and the per-user cost is justified.

Choose Rev human transcription if accuracy on difficult audio is what you are actually buying. Nothing free competes.

Choose Descript if transcription is part of an editing workflow rather than the end product.

Choose Speak AI if you are analysing many recordings rather than reading one, for example coding twenty customer interviews for themes. Local Whisper transcribes them free; it will not tell you what they have in common.

The verdict

The honest split is convenience against control, and cost follows.

If your transcription is routine and non-sensitive, Fireflies' free tier is genuinely good and costs nothing. If your recordings involve clients, health, legal matters or anything you would not email to a stranger, local transcription is not a budget choice. It is the correct one, and it happens to also be free and unlimited.
