Autocorrect, the flag banner, and AI review all pause until you subscribe or enter a valid license key. You'll see a notice in the compose box and in the extension popup explaining this. Nothing is deleted — subscribing (or entering your key) picks up exactly where you left off.

It's emailed automatically the moment you subscribe at chatpolish.com. Paste it into the extension's Settings page (click the ChatPolish icon → Settings) and click Save.

Double-check there's no extra space before or after it when pasting, and that you clicked Save after pasting. If it still doesn't work, email us the key (or the email address you purchased with) and we'll look it up.

No. Your license key follows your subscription, not the device. Paste the same key into ChatPolish's Settings on every computer you use it on.

Press Ctrl+Enter (Cmd+Enter on Mac) instead of Enter, and your chosen AI provider — Claude, ChatGPT, or Gemini — checks the message for grammar and clarity issues. You bring your own API key, entered in Settings. ChatPolish never sees or stores that key or your messages; the request goes directly from your browser to whichever provider you picked. This is entirely optional — regular autocorrect works without it.

Yes, anytime, from the AI provider dropdown in Settings. Each provider keeps its own saved key, so switching back and forth never loses one.

This is usually a WhatsApp Web update changing something ChatPolish relies on. Try reloading the WhatsApp Web tab first. If it's still off, email us what you're seeing (a screenshot helps) — WhatsApp changes are something we actively watch for and fix quickly.

Subscriptions are managed entirely through LemonSqueezy, our payment processor — you'll find a manage/cancel link in your purchase receipt email. For refund questions specifically, email us and we'll help directly.

No. Regular autocorrect runs entirely locally in your browser. See the full Privacy Policy for details, including exactly what the optional AI review sends and to whom.
