Short answer: Yes, Otter.ai transcribes uploaded audio and video files, and it adds speaker labels automatically. But Otter is built for live meetings first, so file upload is a secondary feature with real limits: the free plan allows only 3 imports ever, uploads eat into a monthly minute cap, and every file is processed in Otter’s cloud.
If you searched “does Otter transcribe audio,” you probably have a recording sitting on your drive, an interview, a lecture, a voice memo, and you want to know if Otter will turn it into text. It will. The question is whether Otter’s limits and cloud-only design fit your workflow, or whether you want something different.
What Otter.ai actually is
Otter is a live meeting assistant first, and a file transcriber second. Its flagship feature is a bot (Otter’s Meeting Agent, formerly OtterPilot) that auto-joins your Zoom, Google Meet, or Microsoft Teams calls, transcribes the conversation in real time, labels who said what, and generates a summary with action items afterward.
That is where Otter puts its energy. The typical Otter user is a sales team, a recruiter, or a manager who wants meetings captured automatically without hitting record. Speaker diarization, live captions, and AI meeting summaries are Otter’s strengths, and they are genuinely good.
File upload exists, but it lives in the shadow of the meeting product. You can drag a recording in and get a transcript, yet the plan limits make it clear this is not the main event.
Can Otter transcribe an uploaded file?
Yes. Here is what actually works.
Supported formats. Audio: MP3, AAC, M4A, WAV, WMA. Video: MP4, MOV, AVI, WMV, MPEG, MKV. Otter extracts the audio, transcribes it, and applies speaker labels automatically, which is a real advantage if your recording has multiple people.
Large files. Otter accepts large files (it cites support for sizes up to several gigabytes), so a long recording is usually not a problem on the file-size front.
The limits are the catch. This is where the meeting-first design shows:
- Free (Basic): 3 file imports for the lifetime of the account. Not 3 per month, 3 ever. Once you have used them, you cannot upload again without upgrading.
- Pro: 10 imports per month.
- Business / Enterprise: unlimited imports.
On top of that, uploaded minutes count against your monthly minute cap. Otter meters transcription time across live meetings and uploads combined. A one-hour recording eats an hour of your monthly allowance.
Otter pricing (as of mid-2026, source): Basic is free with 300 minutes per month and 3 lifetime imports. Pro is $16.99/month or $8.33/month billed annually, with 1,200 minutes per month and 10 imports per month. Business is $30/user/month or $19.99 billed annually, with unlimited transcription. Note that Pro’s monthly minute allowance was cut from 6,000 to 1,200 over 2025 to 2026, so older reviews overstate what Pro gives you.
Cloud-only. Every file you upload goes to Otter’s servers. There is no offline or on-device mode. For meeting notes that is usually fine. For a confidential interview or medical audio, it may not be.
Otter vs SnailText for file transcription
If your goal is specifically transcribing files (not capturing live meetings), it is worth comparing Otter to a local tool. SnailText’s file transcription runs Whisper and Parakeet on your own machine.
| Otter.ai | SnailText | |
|---|---|---|
| Primary purpose | Live meeting assistant | Local file + voice transcription |
| Transcribe uploaded files | Yes (with import limits) | Yes |
| Where audio is processed | Otter’s cloud | On your device |
| Works offline | No | Yes |
| Free tier file uploads | 3 for the lifetime of the account | Unlimited on compact models |
| Per-minute meter | Yes (uploads count against cap) | No meter |
| Languages | 6 | 99 |
| Speaker labels (diarization) | Yes | No |
| Live meeting bot | Yes (auto-joins calls) | No |
| Meeting summaries | Yes | No |
| Subtitle export (SRT/VTT) | Limited | Yes (SRT, VTT, TXT, MD, JSON) |
| Pricing | Free · $16.99/mo Pro | Free · $7.49/mo · $89/yr Pro |
The two tools do not overlap as much as the shared “transcription” label suggests. They win at different things.
Where Otter wins
Be honest about this: Otter does several things SnailText does not, and if you need them, Otter is the better choice.
- Live meeting bot. Otter’s agent auto-joins Zoom, Meet, and Teams calls and transcribes them live. SnailText has no meeting bot. It cannot sit in on a call for you.
- Speaker diarization. Otter labels who said what automatically. SnailText does not label speakers in file transcription, it gives you one clean transcript without “Speaker 1 / Speaker 2” tags.
- Meeting summaries and action items. Otter turns a conversation into a structured summary. SnailText transcribes, it does not summarize meetings.
If your job is capturing multi-person meetings with clear speaker attribution and follow-up notes, that is Otter’s home turf, and nothing local matches it cleanly.
Where SnailText wins
For transcribing your own files privately, the local approach has real advantages:
- Nothing is uploaded. Audio is processed on your Mac or Windows machine. No file leaves your device. For confidential interviews, legal audio, or medical recordings, that is the whole point.
- 99 languages vs 6. Otter covers 6 languages. SnailText runs Whisper and Parakeet, which handle 99. If your audio is Polish, Korean, Arabic, or dozens of others, Otter simply cannot help.
- No meter, no lifetime cap. There is no per-minute counter and no “3 uploads ever” wall. Transcribe as many files as long as you want on the compact models, free.
- Subtitle export. SnailText exports SRT, VTT, TXT, Markdown, and JSON, so a video file becomes ready-to-use subtitles. You can also drag whole folders in for batch transcription.
Honest verdict
Otter and SnailText are different tools with a shared word. Do not pick based on the word “transcription.”
Choose Otter if your real need is meetings: live capture of Zoom or Teams calls, automatic speaker labels, and AI summaries. File upload is a bonus, and if you only transcribe the occasional short recording in English, Otter’s free tier or Pro plan will do it. Just remember the 3-file lifetime cap on free, the minute meter, and that everything runs in the cloud.
Choose SnailText if you mostly transcribe your own audio and video files, care that nothing leaves your machine, work in a language outside Otter’s six, or want SRT/VTT subtitles without a per-minute meter. The tradeoff is real and worth stating: no live meeting bot, and no speaker labels in your transcripts.
Otter is a cloud meeting assistant that happens to accept file uploads. SnailText is a private local file transcriber that happens to also do live dictation. Match the tool to what you actually do all day.
SnailText’s free tier is unlimited on compact models, with no account required. Download for Mac or Windows and transcribe a file before you commit to either subscription.
