What our research says

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

Linguix

A cheaper Grammarly substitute whose two genuinely interesting features are not what it leads with: non-English checking and a grammar API you can embed in your own editor. As a pure English writing assistant it trails the market leaders.

Pros

  • multi-language checking that most English-first rivals do not match
  • documented API with a free 1M-character tier for evaluation
  • text-expansion shortcuts bundled instead of sold as a separate tool
  • two-year plan brings the effective price down to about $10/month

Cons

  • a permanent 50%-off banner makes the real list price hard to pin down
  • team and business pricing is not published anywhere on the site
  • very small company — headcount reported in the low single digits in 2026
  • English suggestion quality does not match Grammarly or LanguageTool Premium

Which one fits

Choose Grammarly if you need

  • Anyone writing in a browser, Word or email who wants corrections in place

Choose Linguix if you need

  • writers working in French, German, Spanish, Portuguese, Italian or Polish
  • developers embedding grammar checking into their own product via API
  • teams enforcing one style guide across support and sales writing
  • heavy users of canned replies and text snippets
