Features

Everything you need to navigate
an unfamiliar codebase

Visual Dependency Graph

Interactive force-directed canvas graph showing every file and its import connections. Click nodes for details, double-click to open the file directly.

AI File Summaries

Every key file gets a plain-English explanation of what it does, what it exports, and what it depends on. No more guessing where things live.

Codebase Q&A

Ask anything in plain English. The AI has full repo context and answers with specific file references. Multi-turn conversation with history.

5 AI Providers

Groq, Ollama, Gemini, Anthropic, OpenAI. Type any custom model name. Switch providers anytime without re-analyzing.

Analysis History

Every analysis saved locally per workspace. Load past analyses, compare graphs across refactors, delete when done.

Smart Filtering

Auto-skips node_modules, dist, build, lockfiles, minified files, and generated code across all languages. Only your source code gets analyzed.

How it works

Four steps from zero
to full understanding

The entire pipeline runs locally. The only external call is to the AI provider you configure.

Scan the workspace

Reads all source files. Automatically skips node_modules, dist, build outputs, lockfiles, minified and generated code across all languages.

Build the dependency graph

Extracts every import per language, resolves relative and alias paths, builds a node-edge map of the entire codebase.

Generate AI summaries

Sends batches to your AI provider. Returns a repo overview, architecture description, tech stack, and per-file explanations.

Ask anything

The Q&A agent has full graph, summary, and file context. Multi-turn conversation with history so questions build on each other.

Your code never
leaves your machine

Encrypted key storage

API keys stored in VS Code's SecretStorage using OS keychain. Never written to disk in plaintext.

Zero telemetry

No analytics, no crash reports, no usage events. The extension works fully offline except for AI calls.

Open source and auditable

Every line of code is public on GitHub. Read it, verify it, fork it.
