Changelog

A plain-language list of what has shipped in LettiB.

See the roadmap for what comes next.

1.0.0

Files

• Chat, Compare, and the other attach surfaces list the file types they accept, and the upload message says what happened.
• If a text file cannot be read, LettiB says so instead of keeping a broken copy. A scanned PDF with no text layer gets its own notice too.

Help

• Help chat sends only a recent slice of the conversation, so the answer stays on the question you just asked.
• If you ask to cancel or deactivate your account, help takes you to account deletion. You confirm that yourself under Settings, then Account.

iOS app

• Help inside the iOS app follows the same rules as the rest of the app.
• After you sign in, the app asks once whether it may send notifications.
• You can share an answer, dictate a message, and open chats you already saved while you are offline.
• Source links open inside the app.
• Sign out is on the More menu on your phone.

Workspace

• Compare keeps the models you picked when you come back to a saved round, and the score chips return when the page reloads.
• Opening a saved compare link loads that round and its models.
• Perplexity answers work with web search on or off.
• The homepage walks from a brain of AIs to one answer.
