What sets this editor apart is that the AI is not bolted on as a sidebar but built into the core of the editing experience. A fork of VS Code rebuilt around deep model integration, its agent mode can plan and execute changes that span multiple files at once, so refactoring a feature across a dozen modules becomes one instruction rather than a dozen manual edits. Codebase-aware context means completions and inline edits draw on the whole project, not just the open file, and smart Tab completion anticipates the next change. You keep the familiar VS Code experience while choosing among frontier models. Measured against its alternatives, the difference is architectural: unlike GitHub Copilot, which layers assistance onto an existing editor, this rebuilds the editor around the AI so the two feel like one; and against Windsurf or Cody, its multi-file agent and codebase-wide context are the headline draw. The cost structure deserves a clear-eyed look. It is a subscription on top of underlying model costs, and heavy use can hit usage limits, so the economics suit steady daily work rather than occasional dabbling. A free tier exists, with paid plans from $20 per month. Ideal for developers who put AI at the centre of their workflow and want editor and model tightly fused for coding and data-analysis tasks. Choose it if multi-file agentic editing is central to your day; skip it if a lightweight autocomplete in your current editor already suffices.
