Spelling, Grammar & Style Checker

Instantly applies deterministic corrections (repeated spaces, duplicate punctuation, sentence-start capitalization, excessive line breaks) and optionally offers advanced grammar and style correction with local AI, showing the detected changes, a short explanation, and a comparison between the original and corrected text.

Local rules + optional local AI

Frequently asked questions

Does it invent errors just to look like it's doing something?

No. If it doesn't detect any changes, it says so clearly instead of showing fake corrections.

Does the advanced correction require AI?

The deterministic corrections (spaces, punctuation, capitalization) always work without AI; the advanced grammar and style correction uses the local AI engine when it's available.
