The AI-first IDE.
A desktop IDE with AI woven into editing, debugging, and git — its own architecture from the ground up.
AI Assistant & Agent Mode
Chat with AI grounded in your codebase, or hand off a task to Agent Mode — it reads files, proposes edits for your review, and runs terminal commands with an approval gate at every step.

Real Language Intelligence
A genuine language server (not a heuristic) powers completion, hover docs, go-to-definition, and live diagnostics — the same experience you get in any LSP-backed editor.

Integrated Debugger
Set breakpoints, step through code, and inspect the call stack and variables — a real Debug Adapter Protocol client, not a bolted-on console.log.
Read the docs →
Git, Built In
A full source control panel, an embedded interactive commit graph, and GitHub pull request / issue review — without leaving the editor.

Code Map & Impact Analysis
A visual dependency graph of your workspace, plus AI-assisted "Analyze Impact" — see what a change could break, and which tests to run, before you touch anything.
Read the docs →
Notebook Cells
Run Python cells against a persistent kernel with real cross-cell state, live streaming output, and .ipynb files that round-trip cleanly with Jupyter.
Read the docs →
Extensions
A marketplace for installing extensions, and the tooling to build and publish your own — themes, language servers, debug adapters, and AI tools.

Its own architecture
Built from scratch — not a fork of VS Code or any other editor. An independent codebase, top to bottom.
Real language intelligence
A genuine Language Server Protocol client powers completion and diagnostics — not a heuristic bolted on top.
Approval gates, not autopilot
Agent Mode proposes every file edit and terminal command for your review — configurable per tool in Agent Profiles, from read-only to full autonomy.

Windows and macOS today.
Which AI providers can I use?
Claude, GPT-4o, Gemini, or a local model via Ollama — configured in Settings → AI Provider Credentials.
Can I build my own extensions?
Yes — themes, snippets, language servers, and more, published to the built-in marketplace.
