Grammar Check

Spelling, grammar and style, with every suggestion applied one click at a time.

Needs a server connection
Uses the public LanguageTool API by default. Point it at your own server in Settings to lift the rate limit.

How to grammar check

  1. Paste or type your text. Checking starts as you stop typing.
  2. Read each suggestion with its explanation.
  3. Apply the ones you agree with, one at a time.

Questions

Does my writing get sent somewhere?
Yes — checking grammar needs a language engine, and this uses the public LanguageTool service. Do not paste anything confidential. An administrator can point it at a self-hosted server instead.
Why does it flag correct sentences?
Style rules are suggestions, not errors. Deliberate fragments and technical terms often get marked — that is why nothing is applied automatically.
