Code with an AI agent you can inspect and control.
A local-first desktop coding agent for planning changes, editing files, running tools, reviewing diffs, and keeping every risky action visible.
本网站目前为 2026 年 7 月 10 日发布前预览，价格与功能以正式发布为准。
Four pillars that keep every AI action transparent and in your hands.
Runs entirely on your machine. Your code never leaves your computer.
Plan, code, review, and debug through an AI conversation timeline.
File editing, search, shell, Git, LSP, MCP — all visible and controllable.
Support multiple providers, custom model IDs, secure API key storage.
Nothing happens in a black box. Every step is inspectable and under your control.
Tell the agent what you need in plain language. It reads your codebase to build full context first.
The agent proposes a concrete plan before touching files. Review, adjust, or reject — you stay in charge.
File edits, shell commands, and Git operations stream live. Approve risky actions individually.
Every change lands as a reviewable diff. Accept, iterate, or roll back — full history is preserved.
From a single request to a reviewable diff — switch between real scenarios.
