DeepChat

DeepChat is an AI desktop client for people who want local models, cloud chat and task agents in one workspace. It supports document work, research and coding tasks, with conversation history stored on your device.

• Local and cloud models: Use Ollama or LM Studio alongside DeepSeek, OpenAI, Claude and Gemini, with support for providers using OpenAI, Anthropic or Gemini API formats.
• Agents and tools: Give agents access to files, browsers and other tools through MCP, or use external coding and task agents through Agent Client Protocol (ACP).
• Reusable Skills: Add task-specific instructions and reference material to conversations, and exchange compatible Skills with Claude Code, Codex, Cursor and other agent tools.
• Search and documents: Search the web with customizable engines, including academic search, and analyze, extract information from or translate multiple documents together.
• Resumable sessions: Keep structured records of agent work, inspect requests and tool results, and resume sessions with their context. Remote control connects sessions to Telegram, Feishu/Lark, QQBot, Discord and WeChat iLink.

The app runs on macOS, Windows and Linux and is open source under Apache 2.0. It stores history and API keys locally, while cloud model requests go to your chosen provider. Local model support includes managing Ollama downloads and runs within the app; cloud models and web search require external services.
