Libretto AI-Chat Client

Libretto brings your LibreChat servers to your iPhone: secure, quick to reach and with voice.

Libretto is an unofficial client. You enter the address of your own LibreChat server, and Libretto shows its chat page in a clean, fast app. There is no account with us and no detour through our servers.

MULTIPLE SERVERS, KEPT APART
• Any number of profiles, each with its own isolated browser storage
• Quick switching with the bar at the bottom, with a colour and symbol per profile
• Optional automatic re-login (password and two-factor code), protected by Face ID and the keychain
• Single sign-on (e.g. Microsoft) and MCP authorizations work

VOICE
• Voice mode: you speak, Libretto sends your question and reads the answer aloud sentence by sentence while it is still being written
• Conversation mode with follow-up questions without tapping
• Speech output with the iOS system voice or optionally through OpenRouter with your own key
• The microphone button can be placed anywhere on the screen

ON THE GO AND QUICK TO REACH
• CarPlay: start a conversation hands-free in the car
• Siri and Shortcuts: “Start Libretto”
• Widgets and controls for the Home Screen and Lock Screen
• The conversation keeps running while the screen is locked

PRIVATE
• No ads, no tracking, no analytics
• Your data goes only to the server you enter yourself
• A demo profile to try the app without a server of your own

COST
Libretto is free for private, non-commercial use. For commercial use there is a one-time purchase to confirm it (it unlocks no features) and company licenses on request. If you like, you can support Libretto with a voluntary coffee.

Note: Libretto is not affiliated with the LibreChat project. You need your own LibreChat server or access to one. The operator of the server is responsible for it and its content.
