Otter.ai vs Voice Writer

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors.

The short answer

Entry price: Otter.ai from $8.33/seat/mo, Voice Writer from $10/mo — different billing units, so no direct winner
Free plan: Both have one
Public API: Otter.ai has one; not confirmed by us for Voice Writer
Higher Trust score: Otter.ai — 94 vs 72 for Voice Writer
Best fit: Otter.ai: Teams that live in Zoom, Meet or Teams and want notes without a note-taker · Voice Writer: drafting text by speaking instead of typing, inside Gmail, Docs, or Notion

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
