Similar to CharacterAI, but open source, and with much deeper character customization.

- The whole web app is a single HTML file - no server (serve it locally if you want).
- All your data is stored in your browser's local storage (again, there is no server).
- Share characters with a link - all character data is embedded within the link.
- Auto-summarization algorithm (for old messages) which extends effective character memory/context size massively.
- Characters automatically compress messages into 'memories' and retrieve relevant memories based on context. Can handle as many memories as you need - tens of thousands or more.
- Add lorebook(s) to your character, and add thread-specific lore with the
/lorecommand. - Fully extensible with custom code. See examples here.
- Give your character access to the internet
- Create your own slash commands
- Give your character a video avatar (custom code has its own iframe & can display arbitrary content)
- Create a "game master" with a separate AI-powered process that tracks your abilities, inventory, etc.
- Create your own memory structures (embedding, retrieval, etc.)
- Give your character an internal thought process that runs alongside the chat
- Give your character a voice via the browser's built-in TTS, or via an external API like ElevenLabs
- Characters can edit their own personality and custom code - self-improving and change over time
- Allow your character to execute Python or JavaScript code.
- Currently supports OpenAI APIs and most Hugging Face models.
- Easily import character files and conversation data most other formats.
