Local by default
Cards, lorebooks, and settings live in your browser's own storage. There's no CharacterVault server holding a copy.
CharacterVault is a free, open-source studio for SillyTavern character cards and lorebooks. Edit every field, see how your lore connects, and bring in an AI co-writer when you want one. It all runs in your browser.
Opens and saves
AI, if you want it
The editor
Description, personality, scenario, greetings, example dialogue, system prompt, creator notes. Each one gets a real editor instead of a cramped text box.
Lorebooks
Lorebooks get their own library beside your characters. Link one book to as many characters as you like, then open the recursion map to see which entries trigger which, and fix the keys right there.
AI, optional
Connect OpenRouter, NanoGPT, a local model in LM Studio, or any OpenAI-compatible API. Your prompts go straight from your browser to that provider, and nothing on your card changes until you accept it.
Select any passage and tell the AI toolbar what you want. The rewrite previews in place, and you decide whether it stays.
The Agent reads your open card or lorebook, then fills, rewrites, and trims it while you watch each step. Turn on review to approve every change in a diff first.
Rekey the lorebook entries to proper nouns and trim anything empty.
Every card section and every lorebook entry has a toggle. The AI sees what you pick and nothing else, so prompts stay lean and answers stay on target.
Live demo. Click a section to toggle it.
Describe a character, or pick traits from the tag library, and the Creation Studio drafts every field in front of you. Reroll what you don't like, then save it to your library.
Your work stays yours
Your library stays on your device, and every change can be compared, undone, or backed up. Try the bold rewrite. You can always go back.
Cards, lorebooks, and settings live in your browser's own storage. There's no CharacterVault server holding a copy.
Save a point before the risky rewrite. Compare versions side by side, then restore the whole card or a single change.
Export your whole vault as a single ZIP. Import it to restore your library in any browser.
The companion extension adds Export to CharacterVault to SillyTavern's export menu. One click and the card lands in your vault, image included.

Everything below, for everyone
Yes. Every feature is free to use, with no account, trial, or paid tier. The project is open source under GPL-3.0.
No. The editor, lorebooks, import, export, snapshots, and backups all work without AI. If you want AI help, connect any OpenAI-compatible provider, including a free local model through LM Studio.
In your browser's storage, on your device. CharacterVault has no server that stores cards. Export a card or make a vault backup whenever you want a copy somewhere else.
Yes. Import PNG or JSON cards (V2 and V3) and standalone lorebook JSON, edit them, and export them back. The companion extension can also send cards straight from SillyTavern.
Yes. The app runs in mobile browsers, with layouts made for small screens. A bigger screen is more comfortable for long writing sessions.
Clearing site data removes your local library, as it would for any app that stores data in the browser. Use Backup in the library header to save a ZIP of your cards, lorebooks, and settings, and import it to restore.
Yes. Clone the GitHub repo, run npm install and npm run dev, and it runs on your machine.
