What our research says

AudioBriefly

The good idea here is the delivery route: no app to install, no file to upload — you forward the voice note inside WhatsApp and the transcript comes back where the message was. Minutes-based plans are easy to reason about, and the free tier is enough to test the transcription quality. The weakness is transparency: prices only appear inside Paddle at checkout, and there is no API, so this stays a personal-use tool.

Pros

Works inside WhatsApp with no app install or file upload step
Web app accepts uploaded audio and MP4 video for non-WhatsApp material
Plans metered in plain minutes per month rather than opaque credits
Free tier of ten minutes a month needs no card, and the interface covers English, Italian and Spanish

Cons

No price is visible anywhere on the site — Paddle renders it only at checkout
No API and no bulk upload, so it does not scale past personal use
Free tier caps WhatsApp usage at three voice messages a month
Run by a single Italian sole trader, with the support surface that implies

Otter.ai

Still the default for English-language meeting notes, and the free tier is unusually usable. What determines the right plan is not features but the per-conversation ceiling: 30 minutes on Basic and 90 on Pro means a standard hour-long review truncates on the free tier and a workshop truncates on Pro. Pick the tier by your longest recurring meeting.

Pros

300 free minutes a month makes evaluation real rather than token
Annual Pro at $8.33 is roughly half the month-to-month rate
An MCP server is exposed from the free tier, so assistants can query transcripts without the paid API
Business removes the minute cap entirely rather than raising it

Cons

The API and webhooks require Enterprise, which is quote-only
Per-conversation ceilings (30 min free, 90 min Pro) cut recordings mid-meeting
Basic allows three file imports in total, not per month
Month-to-month pricing is roughly double annual at both self-serve tiers
