SillyTavern

SillyTavern is a free, open-source chat interface for AI language models. It runs on your own computer and connects to many model providers through their APIs. An API is a connection that lets one program talk to another service. You can use it for roleplay, writing help, or casual chat with AI characters. It supports text, images, and voice through add-ons. The project is community-run and carries an AGPL-3.0 license. Check the official docs for setup guides and current features.

Key Features

1. Multi-Provider API Support

One interface connects to OpenAI, Claude, Mistral, OpenRouter, NovelAI, and more. You pick the provider and model for each chat.

2. Local Installation

SillyTavern installs on your own machine with NodeJS 20 or newer. Your chats stay on your computer, and the app tracks no user data.

3. Character Cards and Roleplay

Load AI characters from shareable character cards. Each card holds a persona, greeting, and backstory for roleplay chats.

4. World Info (Lorebooks)

World Info stores facts about your story world. The app inserts the right facts into the prompt when they become relevant.

5. Visual Novel Mode

A visual novel layout shows characters as sprites over backgrounds. It turns chats into a storybook-style visual scene.

6. Image Generation Integration

Connect Automatic1111 or ComfyUI to generate images in chat. Characters and scenes can get AI-made pictures on demand.

7. Extensions and Customization

Third-party extensions add new tools and panels. The interface is highly customizable, with deep prompt controls for power users.
