Limits
Section titled “Limits”- Drafts can be up to about 4,000 characters, fewer in languages such as Korean or Japanese. On iPhone and Android, the button disappears when a draft is longer. In the web app, the button stays, but polishing a longer draft fails, so shorten it first.
- The rewrite stays in your draft’s language.
- If polishing fails, you see Couldn’t polish this message. Try again. with a Try again button, and your draft doesn’t change. The desktop app shows errors in a banner.
AI can change your meaning or drop details, so read the rewrite before you send it.

Section titled “Use a conversation starter”When you open a direct chat that has no messages yet, up to 3 suggested openers appear above the message box.
- Start a direct chat with someone you haven’t messaged yet. Chats and groups explains how.

- Edit it if you like, then send it.
- AI writes the openers using only your app language and the names and usernames of you and the other person, never messages. The app doesn’t label them as AI.
- If the AI doesn’t answer quickly, you see a few standard openers instead.
- Openers appear only in direct chats, not in groups.
