AI coding assistant.
Runs on your machine.
Agentic, private, zero telemetry. Powered by Ollama, LM Studio, Anthropic, OpenAI, Groq, Mistral, Gemini, and any OpenAI-compatible API.
Everything you need, nothing you don't
Chat
Streaming chat with PLAN and BUILD modes. Multiple sessions, compact history, export to Markdown.
Agentic Loop
The model reads, writes, searches, and runs terminal commands in your workspace. Per-action approval for destructive operations.
RAG
Your codebase is indexed with BM25 + optional semantic embeddings. Relevant files are automatically attached to every message.
Inline Autocomplete
Ghost-text completions as you type. Adaptive debounce, word-by-word accept, per-language model routing.
Inline Edit
Select code, press Ctrl+Shift+I, describe what you want. Review the diff, accept or reject.
MCP Support
Connect any Model Context Protocol server. Tools are namespaced and gated behind per-action approval.
@ Context
Attach files, selected code, git diffs, terminal output, web pages, and VS Code diagnostics with @.
Notebook Support
Jupyter notebooks are indexed and readable by the agent. Cell content is extracted and understood as code.
Vision
Paste or upload images into chat. Works with Ollama vision models (llava, qwen2-vl) and all cloud providers that support it.
Memory
Persistent instructions injected into every chat. Auto-saves as you type. Amber dot on the icon when active.
Your choice of model
Local models work out of the box with no account required. Cloud providers are optional — bring your own key.
