A multi-platform AI chat client that connects to any model you choose
Configure the AI providers or API keys you already use, and switch between them inside the client instead of committing to a single bundled service.
Native apps for Windows, macOS, Linux, iOS and Android keep your conversations and settings aligned across devices.
Drag in PDF, Word, Excel, PowerPoint, code and image files and let the model summarise, extract or analyse the content directly.
Edit the same image across multiple turns, automatically carrying over the previous version and merging several images while keeping subjects consistent.

Every AI conversation, one open-source workspace
Connect OpenAI, Anthropic, Google, Azure, AWS Bedrock, Mistral, Groq, Ollama, OpenRouter and many more, then switch models inside a single conversation.
Build specialized agents that carry their own files, tools, reusable instructions and delegated subtasks with separate context.
Turn chat output into interactive apps, React or HTML pages and Mermaid diagrams, and execute code in multiple languages in an isolated sandbox.
Connect any tool or service through Model Context Protocol, and give any model live internet access with built-in search and reranking.
