Free and open source

Features

Built for people who write a lot of characters

From a rough idea to a finished card, the whole workflow lives in one tab.

01

A library that scales with your cast

Import cards from PNG or JSON, search and sort everything, and export back to SillyTavern whenever you like. No lock-in, ever.

02

An editor that goes deep

Every field of the V2 and V3 spec is editable: description, personality, scenario, alternate greetings, and full SillyTavern World Info lorebook fields.

03

Orion, your co-writer

Highlight any passage and ask Orion to tighten it, expand it, or take it somewhere new. Or open a chat and brainstorm from scratch.

04

Context you control

Every section of the card is a toggle, down to single lorebook entries. The AI sees what you pick, and nothing else.

05

Snapshots you can trust

CharacterVault saves versions as you work. Try the risky rewrite; if it flops, roll back to any earlier snapshot in one click.

06

Private by default

Cards live in your browser's IndexedDB. There is no account to make, no server copy, and nothing to leak.

Lorebook Vault

Your lorebooks,
unbundled.

Lorebooks get a library of their own, right next to your characters. Create, search, import, and export standalone books. Then link one book to many characters and edit in one place. Everything stays local, in your browser.

  • Standalone library beside your characters
  • Link one book to many characters, edits sync
  • SillyTavern scan settings round-trip on import and export

Recursion map

See every unlock path
at a glance.

Open a book as a fullscreen web of entries. Arrows show which entries can unlock which. Pan, zoom, and hover to trace chains, pin paths to inspect them, and fix your book without ever leaving the map.

  • Visual web of which entries unlock which
  • Edit keys and flags without leaving the map
  • Staged bulk edits: review, apply, or discard

AI co-writer

Highlight. Instruct. Accept.

Select any passage, tell Orion what you want, and watch the rewrite preview in place. Nothing changes until you accept it.

New in 1.4.0 — the Agent

Describe the edit.
The Agent writes the card.

Orion talks back. The Agent rolls up its sleeves: it reads your open character or lorebook through tools, then fills, rewrites, and cuts for real — while you watch the tool calls live.

You

Rekey the lorebook entries to proper nouns and trim anything empty.

Context

Send what you need,
not what you have.

Every section of the card is a toggle. Orion only sees the parts you pick, so prompts stay lean and answers stay on target.

  • Per-section toggles for every field
  • Custom notes you can paste per character
  • Live token estimate against your limit

AI Creation Studio generating a character from a concept

AI Creation Studio

From a sentence
to a full character.

Describe who you are imagining, or pick from guided trait tags, and the studio drafts the whole card in front of you. Stop it mid-stream, reroll what you don't like, then save straight to your library.

  • Free-text concept or guided tag picker
  • Each field generates live, in order
  • Nothing saves until you approve it

Companion extension

Straight from SillyTavern.

The CharacterVault Export extension adds an "Export to CharacterVault" option right inside SillyTavern's export menu. One click and the card lands in your vault, image included.

On mobile the export falls back to plain JSON, so the card's image stays behind.
