It turns ChatGPT Web (including Pro) into Codex and Claude Web into Claude Code, and also supports DeepSeek, Gemini, Grok, Kimi, and GLM. It requires no API key, MCP, tunnel, or plugin, and uses your own web AI account and quota. It requires Node.js 20.x β‰₯20.17, 22.x β‰₯22.13, or β‰₯23.5, plus Chrome/Chromium, and runs on macOS, Linux, and Windows, with preview support for WSL2 + WSLg. Installation is via npm install -g wtagent; running wtagent opens a dedicated Chrome profile where you sign in with your own web AI account, with ChatGPT as the default provider.
