Graphify Knowledge Graph Pipeline for AI Coding Assistants

Graphify (80K+ GitHub stars, Y Combinator S26, MIT License) is an open-source knowledge graph skill for AI coding assistants that turns any folder of code, documentation, PDFs, images, and videos into a queryable knowledge graph with a single command: /graphify . . It uses tree-sitter AST extraction across 33 programming languages to build a structured web of nodes and edges capturing every relationship in the project. Output includes interactive browser visualization (graph.html), human-readable report (GRAPH_REPORT.md), and full queryable JSON (graph.json). Graphify registers as a skill in Claude Code, Codex, OpenCode, Cursor, Gemini CLI, GitHub Copilot CLI, VS Code Copilot Chat, Aider, Devin CLI, Kiro, and 15+ other assistants. All code parsing happens on-device with zero API calls. Optional integrations include Neo4j, FalkorDB, Obsidian, MCP server mode, and auto-sync via --watch. Leiden clustering surfaces hidden concept communities. Graphify consistently benchmarks as the top-performing knowledge graph tool for AI coding assistants across recall, precision, and agent task completion.

BUSINESS PROBLEM

AI coding assistants operate on flat-file context. Every time you ask a question, the assistant greps through files, reconstructing understanding from scratch. According to Graphify benchmarks (July 2026), this flat context approach wastes 40-60% of tokens on re-reading files the assistant has already seen. For a developer making 50 queries per day, that is 10,000-15,000 wasted tokens daily. More importantly, flat context misses relationships across files. An assistant cannot trace from a database table through an API handler to a frontend component without significant prompting. Graphify pre-computes this map. One query traces the full path. For new developer onboarding, the traditional approach takes approximately 3 weeks of reading docs, pinging colleagues, and grepping code. With Graphify, a new developer runs /graphify . and gets a complete codebase map in 4 minutes. The knowledge graph persists across sessions, commits to the repository (graphify-out/), and every teammate's assistant queries the same graph with zero setup. On a 50-person engineering team, this saves an estimated 1,500 hours of cumulative onboarding context-building per year.

WHO BENEFITS

Senior developer onboarding to a new codebase who faces 2-3 weeks of reading docs, grepping files, and asking colleagues before becoming productive. /graphify . delivers the full codebase map in 4 minutes. Engineering manager of a 50-person team who wants every developer's AI assistant to have full codebase context without each developer configuring their own tools. Platform engineer responsible for tooling at a company using multiple coding assistants (Claude Code + Cursor + GitHub Copilot) who needs a single knowledge graph shared across all platforms.

HOW IT WORKS

Step 1 - Initialize. Type /graphify . in any supported AI coding assistant. Step 2 - AST Extraction. tree-sitter parses the codebase across 33 languages extracting functions, classes, call graphs, database schemas, and imports — all on-device, zero API calls. Step 3 - Graph Construction. NetworkX builds a knowledge graph with nodes (functions, classes, files, tables) and edges (calls, extends, imports, references). Step 4 - Clustering. Leiden clustering detects hidden communities of related concepts across the codebase. Step 5 - Output Generation. Three files are produced: graph.html (interactive visualization), GRAPH_REPORT.md (key concepts and surprising connections), graph.json (full queryable graph). Step 6 - Agent Querying. The coding assistant queries the graph instead of grepping files, reducing token usage by 40-60% per query. Step 7 - Auto-Sync. With --watch, Graphify reindexes on file changes automatically. Step 8 - Optional Export. Export to Neo4j, FalkorDB, Obsidian, or MCP server for advanced workflows.

Persists across sessions: graphify-out/ commits to repo, shared by entire team.

CAVEATS

LOW - Initial graph construction on very large monorepos (500K+ files) may take 5-15 minutes; use --watch for continuous incremental updates. MEDIUM - Image and video extraction requires vision model integration; basic text extraction from images works, but deep video understanding requires additional processing. LOW - The 33-language tree-sitter coverage covers most production stacks but may miss niche or legacy languages. MEDIUM - Graph quality depends on codebase health; heavily duplicated code, dead code, or spaghetti architecture produces less useful graphs.
