The final check before you share.

Corrections first

A dedicated proofreading instruction focuses on spelling, grammar and punctuation rather than creative rewriting.

Your voice stays yours

Correct writing is left as close to the original as possible. Use the rewriter when you want a different style.

Review the changes

Compare deletions and additions in the change view. AI suggestions can make mistakes, so you always have the final say.

The model is instructed to keep the original language. Quality varies by language; important writing should be reviewed by a fluent speaker.
