C.AI Saver by Miku

C.AI Saver lets you keep a local copy of your character.ai conversations and characters, and read them later even without an internet connection.

Chats
- A save button appears next to the Send button on any character.ai chat.
- It scrolls up to load the whole history, then saves the messages, the character's avatar and description, and your persona.
- Saving the same chat again updates it.

Characters
- On the character creation/edit page, a "Save character" button keeps the name, tagline, description, greetings, definition, visibility and avatar.
- You can copy each field to recreate the character elsewhere.

Library
- Click the extension icon to open your library (on Android: menu → Extensions → C.AI Saver).
- Search, read chats like in a messaging app, export or import everything as JSON.
- Settings: language (English / Français and more), theme, accent color, text size.
- Works on desktop and on Firefox for Android.

Privacy
All data is stored locally in your browser. Nothing is sent to any server and no data is collected. The extension only needs access to character.ai (to read the page) and characterai.io (to download avatar images so they work offline).
