Its multimodal chat interface accepts images, PDFs, documents, presentations, and other text-based files. Advanced conversation tools include message branching, response regeneration, and switching models within conversation branches. The application integrates web search engines, MCP tools, and image generation services. Additional capabilities include text-to-speech, speech recognition, and detailed usage statistics. Conversations and settings are stored locally, with optional WebDAV and S3-compatible backups.
