About Proofread Bot — Grammar & Spell Checker
Proofread Bot is a grammar checker and spell checker that proofreads the field you are already typing in. It finds grammar, spelling, and punctuation mistakes on the page, underlines them, and lets you accept a fix in place — no new tab and no copy-paste.
Use it in Gmail, Messenger, LinkedIn, Outlook on the web, Slack in the browser, and most other sites with a text box.
What you get
• In-place grammar check and spell check while you write
• Orange underlines on clear mistakes — click Accept or Ignore
• Works in email, chat, comments, and forms
• Keyboard shortcut: Alt+Shift+P
• Optional live checking while you type (Premium). Free accounts check on demand
How to use it
1. Sign in with Google from the toolbar icon, or right-click a field and choose “Sign in and check with Proofread Bot”.
2. Click in the email, chat, or form field you are writing in.
3. Right-click the field or selected text → Check with Proofread Bot. Or press Alt+Shift+P.
4. Click an underline, then Accept to apply the replacement, or Ignore.
5. If you click away or reload, use “Show saved highlights” to bring the marks back.
Notes
• Google Docs is not covered here — use the Proofread Bot Docs add-on.
• Sign-in is required so checks run on your Proofread Bot account.
• Highlights stay in this browser for a short time so you can restore them on the same field.
• The extension sends anonymous usage events only. It does not send the text you type or the page you are on.
