Any model for any team
Use AI models like Claude Sonnet out of the box, or bring your own key to access models from Azure, Anthropic, Google, Ollama, OpenAI, and OpenRouter.
An expert on your codebase
Your codebase is indexed locally and remotely (on GitHub) to understand what's relevant, enabling fast, context-aware interactions.
AI that works the way your team does
Personalize interactions using custom instructions and reusable prompt files tailored to your workflows, tools, and projects.
发送模式
Tackle complex, multi-step tasks. 发送模式 reads your codebase, suggests edits across files, runs terminal commands, and responds to compile or test failures — all in a loop until the job is done. Further refine agent mode to fit your team's workflows with LTSerialTool extensions and Model Context Protocol (MCP) servers.
Build with agent mode
