TextAdviser fixes spelling and punctuation right in the text field where you write: email, chat, forms, documents in the browser. Mistakes are listed with corrections, "Fix all" changes the text in place and Ctrl+Z undoes it. Grammar, paraphrase, plagiarism and AI-text checks run from the same panel. How it works 1.
