What our research says

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

Voice Writer

Voice Writer is a dictation tool built around real-time cleanup rather than raw transcription — it fixes grammar and adapts to how the user writes as they speak, instead of handing back a literal transcript to edit later. The free web plan is limited to English, and the more useful multi-language and style-adaptation features sit behind the $10/month Pro tier; the on-device Mac app is a genuinely separate, fully free option for anyone who doesn't need the browser integrations.

Pros

  • grammar correction happens in real time while speaking, not as a separate editing pass
  • native Mac app runs fully on-device and is free with no account requirement
  • browser extension integrates directly with Gmail, Docs, and Notion rather than requiring copy-paste

Cons

  • free web plan only supports English
  • no Windows or Linux desktop app, only Mac
  • no API for developers to build on

Which one fits

Choose Voice Writer if you need

  • drafting text by speaking instead of typing, inside Gmail, Docs, or Notion
