Gurren - Copilot for Development

Modern IDEs are powerful but overwhelming. New features hide behind menus, shortcuts differ between tools, and generic chatbots hallucinate steps or ignore which editor you actually have open. Gurren is a Windows desktop copilot built for developers who live in Cursor, Visual Studio Code, or Google Antigravity. Press Ctrl+Shift+Space anywhere in your workflow to open a lightweight panel. Ask natural-language questions—“How do I open the command palette?” or “Where is GitHub Copilot?”—and get answers grounded in a curated markdown vault, not random web guesses. Gurren detects your active IDE and file context automatically, then routes each question through a three-tier retrieval pipeline designed for speed and privacy: • Level 1 — Instant tag lookup over a pre-built index for common questions with zero latency. • Level 2 — Semantic search with ChromaDB and local embeddings (Transformers.js) over hundreds of structured vault notes scraped from official docs. • Level 3 — Optional escalation to Anthropic Claude when the vault is not confident, including a dedicated PRD/spec mode that turns product requirements into IDE-specific build guides. When an answer references a UI control, Gurren draws an on-screen pointer overlay on top of your desktop so you know exactly where to click. A persistent memory layer writes usage patterns to vault/user (profile, history, unknown queries) so the assistant improves with you over time. The stack is Electron + React + TypeScript on the front end, Python scripts for vault seeding and indexing, and ChromaDB running locally—routine answers work offline; only Level 3 needs an API key. Gurren is local-first, context-aware, and built for real IDE workflows—not another browser tab.
