Bring your JanitorAI bot to SillyTavern.
JanitorAI has no official card export, so the usual path is a card file you already have: your own bot's definition, a card the creator shared as PNG or JSON, or a download from a mirror that lists cards with public definitions. Whatever file you're holding, this converter turns it into a V3 PNG that SillyTavern imports in one drag.
Convert a card
Drop in a card and download. Everything runs locally in your browser — nothing is uploaded.
PNG, JSON, or .charx. Converted entirely in your browser — the file never leaves your device.
Importing to a hub (RisuRealm / Chub)? .charx or V2 PNG are accepted most widely. A bare V3 JSON has no embedded avatar, so some hubs reject it.
Conversion notes
Pick a card and a target format, then convert. Any fields that don't survive are listed here so you can review them before downloading.
The route
Get your card file
For your own bots, copy the definition from the creator page into a JSON card, or use the PNG/JSON file you originally uploaded. For other creators' cards, use a file they shared — this tool converts files, it doesn't fetch anything from JanitorAI.
Drop the file below
PNG, JSON and .charx are all accepted; the spec version is detected automatically.
Convert to V3 PNG
If the source was bare JSON with no avatar, the output uses a placeholder image — swap the avatar after import.
Import into SillyTavern
Drag the PNG into the character panel. Set up your own API key in SillyTavern — that part JanitorAI was doing for you.
Questions
- Can this extract a bot with hidden definitions?
- No — and that's by design. This converter transforms card files you already have; it cannot and does not pull definitions from JanitorAI. Respect creators' choices about what they publish.
- My JanitorAI card is just text fields. How do I make it a card file?
- Paste the fields into a minimal JSON card (name, description, personality, first message), save it as .json, and drop it here — the converter upgrades it to a proper V3 card and can embed it into a PNG.
- Why do my JanitorAI bots feel different in SillyTavern?
- Model and prompt template matter as much as the card. JanitorAI wraps your card in its own system prompt; SillyTavern gives you full control, which usually means better results after some preset tuning.
