Chat2API is a desktop app that lets you connect to many AI service providers using a common API. You can use it with any client that works with OpenAI’s API. This means you can use services like DeepSeek, GLM, Kimi, MiniMax, Qwen, and Z.ai all in one place. It works on macOS, Windows, and Linux.
Chat2API acts as a bridge between you and different AI services. Instead of using each service separately, you launch Chat2API on your computer. Then you connect your existing OpenAI-compatible software to Chat2API. It will send your requests to the AI service you choose, without making you learn new tools or platforms.
This makes managing AI tools simpler. Whether you want to try DeepSeek’s chat, use GLM-5’s language generation, or test Qwen3, Chat2API handles it all behind the scenes.
Before you start, make sure your Windows PC meets these needs:
- Windows 10 or newer (64-bit recommended)
- At least 4 GB of RAM (8 GB or more for better performance)
- Minimum 500 MB of free disk space
- Internet connection (required to access AI services)
- A standard keyboard and mouse
