What our research says

Fixkey

The appeal is that it works in every Mac app rather than a walled editor, and dictation comes bundled instead of being sold separately. At $48 a year it undercuts the usual writing-assistant subscriptions by a wide margin. The vendor is now named in an imprint — Headstart Ventures UG in Berlin — but it is still a small operation with a single support address.

Pros

  • Works system-wide in any macOS app rather than only a dedicated editor
  • Speech-to-text and translation across 180-plus languages sit behind the same key
  • Custom prompts let you pin the rewrite style
  • Flat 48 dollars a year with no per-seat tiering

Cons

  • macOS only: no Windows build and no browser extension found
  • Small vendor with one support address and no published SLA
  • No free tier is advertised on the pricing page

Grammarly

Still the default for catching mistakes inside other people's software, but the free tier has quietly become an AI-prompt meter and the honest price is $30 unless you commit to a full year.

Pros

  • Runs inside the apps people already write in rather than as a separate editor
  • Free tier still covers spelling, grammar and tone detection with no time limit
  • Pro folds in plagiarism and AI-text detection that rivals charge for separately

Cons

  • The $12 headline is the annual rate; paying monthly costs $30
  • Free AI allowance is 100 prompts a month and depletes quickly
  • No public API, so it cannot be embedded in another product
  • Enterprise pricing is not published anywhere on the site
