A fast, lightweight desktop app for AI coding CLIs.
Website · Download
Chat apps just talk. Caipi gives Claude Code and Codex CLI a proper desktop interface -- so AI can read your files, run commands, and make changes, all with a visual layer that shows you what's happening.
No API keys needed. Caipi wraps the CLIs you already have installed, using your existing subscription.
- File Explorer -- Browse your project tree in a sidebar with real-time file watching. Double-click to open files in your default editor.
- Session History -- Pick up where you left off. Sessions are loaded from the CLI's own logs, grouped by project folder.
- Permission Modes -- Control what the AI can do. Default prompts for dangerous operations, Edit auto-allows file changes, Allow All bypasses everything.
- Model Switching -- Cycle between models (Opus, Sonnet, Haiku for Claude; GPT-5.x for Codex) without leaving the chat.
- Extended Thinking -- Toggle thinking depth (Low / Med / High) for models that support it.
- Context Tracking -- See how much of the context window is used at a glance.
- Task & Skill Sidebar -- Track agent todos and active skills in a collapsible panel.
- Streaming -- Real-time text and tool call display as the AI works.
- Tool Visibility -- Inline collapsible tool call stacks showing what the AI is reading, writing, and running.
- Auto-Updates -- Built-in update mechanism keeps you on the latest version.
- Light & Dark Mode -- Follows your system preference or set it manually.
You need at least one of the following CLIs installed and authenticated:
- Claude Code -- Requires a Claude Pro or Max subscription.
- Codex CLI (optional) -- Requires an OpenAI API key or subscription.
Caipi detects installed backends automatically on startup.
