Best for

Pick Graphify if you want a local-first, open-source knowledge graph over your own code, docs and meetings instead of yet another cloud RAG service.

Skip if

Skip it if you need a production-ready product today or a managed hosted RAG API with SLAs.

Graphify is an MIT-licensed knowledge graph engine that ingests heterogeneous inputs — source code (with AST awareness), markdown docs, PDFs and papers, meeting transcripts, browser history, even images and diagrams — and decodes them into a single traversable graph. The pitch is 'any input, one graph, complete recall': instead of throwing everything into a vector store and praying for retrieval, it builds explicit nodes and edges that you can walk to surface relationships like 'this RFC ↔ this commit ↔ this meeting decision'. It runs on-device by default with an optional cloud mode.

The differentiator versus generic RAG stacks is the incremental graph maintenance and the local-first posture: when a file changes, only affected nodes and edges update, so the corpus stays coherent at millions of files without re-embedding everything. That makes it interesting for engineers and researchers who want long-horizon memory over a private corpus rather than a chatbot wrapper. As of this writing the project is in waitlist / early-access; the marketing copy leans heavily on MIT licensing and 'free forever' framing, so expect a community-driven OSS release with cloud add-ons later rather than a polished SaaS today.

Editor's take

Promising positioning — on-device, MIT, graph-native — and exactly the kind of project the RAG space needs more of. But it's still a waitlist landing page with bold claims and thin technical disclosure, so treat it as one to watch rather than one to deploy. Worth bookmarking until the repo and docs land.

Pros

✅ MIT-licensed and runs fully on-device — no data leaves your machine
✅ Incremental updates: only changed nodes/edges re-process, scales to millions of files
✅ Ingests broad input set: code/AST, docs, papers, meetings, browser history, images
✅ Explicit graph beats opaque vector retrieval for traceable, multi-hop questions
