Reporting in, recruit. Stow your gear, we jump in ten.
Not just an API.
A chat client too.
Open it and start talking. Free models are already connected, so there's no signup, no key, and no setup. Pick a character or import your own, and your chats stay in your browser.
Free models wired in on the backend. Just open and chat, no account needed.
Personas, presets, prompt templates, and SillyTavern card import built in.
Conversations live in your browser, never on our server. Bring your own OpenAI-compatible endpoint and key too, fired straight from the browser.
Lorebooks, group chat, swipes, and a real character chat engine, not a toy box.
Integrate in seconds.
Scale to infinity.
Fully OpenAI-compatible endpoints. Switch from any provider without changing your code. One API key, every model.
