Extractor uses LLMs to reliably extract structured data from any webpage. Unlike traditional scrapers that break when HTML changes, Extractor understands the content semantically.

GitNexus is a zero-server, client-side code intelligence engine that runs entirely in your browser. Drop in a GitHub repo URL or ZIP file, and it builds an interactive knowledge graph that maps every function, import, class inheritance, and execution flow — no backend required, no code ever leaves your machine. It uses Tree-sitter WASM for AST parsing, LadybugDB for in-browser graph storage, and HuggingFace transformers.js for fully local embeddings. On top of the graph sits a built-in Graph RAG agent you can query in plain English. Ask "where does authentication happen?" or "what calls this function across the codebase?" and get precise answers backed by structural graph traversal rather than fuzzy keyword search. Eight languages are supported out of the box: TypeScript, JavaScript, Python, Java, Go, Rust, PHP, and Ruby. GitNexus also ships an MCP server, letting Claude Code and Cursor tap directly into the live knowledge graph for full codebase structural awareness mid-session. It hit #1 on GitHub trending in April 2026 with 28k+ stars — a clear signal that developers are starving for AI agent context tooling that doesn't send their proprietary code to a third-party cloud.
Reviewer scorecard
“Traditional web scraping is brittle. LLM-powered extraction that understands content structure is the right approach. Works on messy pages where CSS selectors fail.”
“This is the missing layer between your codebase and your AI agents. The MCP integration means Claude Code can now actually understand your repo structure instead of guessing from file names. The privacy-first, zero-server approach makes it the only option I'd trust with client code.”
“The LLM cost per extraction makes it expensive at scale. But for high-value data extraction where accuracy matters more than cost, it is worth it.”
“Running complex AST parsing and embedding generation in the browser via WASM sounds great until you try it on a 500K-line monorepo — the browser tab will struggle badly with memory limits. There's no authentication, no team sharing, and the graph state evaporates on refresh. Build the MCP server into a proper local daemon first, then we'll talk.”
“Web scraping becomes web understanding. As more AI agents need to read the web, tools like Extractor become essential infrastructure.”
“Graph-native code understanding is the inevitable next step past flat file retrieval. When AI agents can reason about call graphs and dependency chains instead of just token proximity, whole new classes of autonomous refactoring become possible. GitNexus is an early but crucial proof of that future.”
“The interactive knowledge graph visualization alone is worth it for onboarding new teammates. I've never been able to explain a legacy codebase this fast — you can literally point at a node and say 'this is the problem.' Pair it with an AI agent and it becomes a live explainer.”
