OpenProof

Spelling and grammar checked as you write, in every app you write in. Like Grammarly, but it only fixes mistakes, never the way you put things.

• Mistakes only

  Spelling, grammar, punctuation and capitals. Your wording is left alone: no suggestions to sound clearer, shorter or more formal.

• In every app

  Gmail, Slack, WhatsApp, Word, Teams and the rest. Mistakes are underlined in place; right-click one to see the fix, then accept or ignore it.

• Never in the way

  Each sentence is checked as you finish it, in the background. A small badge on the text box shows the count; Ctrl+Alt+Q lists every fix and Enter accepts them all.

• Made for OpenWhisper

  Dictate with OpenWhisper, then OpenProof tidies the result. Right-click the badge to have the whole message rephrased when you want it.

Checks go to Google's Gemini (or any OpenAI-compatible model you choose), one sentence at a time. Password fields are skipped.
