Knowledge graph
Every link becomes an edge. Watch clusters, hubs and orphans emerge from notes you forgot were connected.

Built on HTML — the format Anthropic's engineers adopted · Free to use · Powered by local AI
HTML is the new Markdown
HTML-first, Markdown supported — a knowledge graph and local RAG in one privacy-first engine, where it all finally clicks together.
For developers
Anthropic's engineers have already moved their specs to HTML. DocGraph was built for it.
Anthropic's engineers have already adopted HTML for their specs, plans and code reviews, dropping Markdown — because HTML is richer, more readable, and the only format that's first-class for both humans and AI agents. That's the exact conviction DocGraph shipped on from day one: your HTML is the source of truth, never flattened, never converted. Fenced code stays editable, Mermaid renders beside your prose, and an MCP server lets your tools work the vault — every write confirmed by you.

For research & writing
Ask your own notes, and get answers that cite their sources.
The graph surfaces connections you forgot you made, backlinks show every note that references this one, and the local AI answers from your vault with citations — tuned to say "I don't know" rather than invent.
For business
Your documents never leave the building — because they never leave the machine.
Contracts, plans and internal docs stay plain files on disk: no cloud, no account, no telemetry, and network egress is default-deny. Secret detection flags stray API keys, and the app is free — nothing to procure.
For ideation
Think on an infinite canvas, next to the notes that sparked the idea.
Whiteboards live inside your vault: sketch with the pen, arrange text cards and shapes, embed your documents, even design a database schema with ERD tables — then let it all join the same graph as your writing.
A graph view, an AI that respects you, and your files left untouched.
DocGraph reads the HTML you already have and reveals the structure hiding inside it.
Local AI chat
Ask questions across your vault with Ollama and in-process embeddings. Nothing leaves your machine.
Private by default
Network egress is default-deny and surfaced live. A note can't silently phone home.
Your vault is just files. It stays that way.
No proprietary format, no lock-in, no account. DocGraph is a lens over the plain HTML on your disk — close the app and everything is exactly where you left it.
How privacy works →- Local-first — plain files on your machine, always readable.
- No telemetry — by default, and no silent cloud ever.
- AI runs locally — Ollama plus in-process embeddings.
- Free to use — no account, no payment, no tier.
Your knowledge. Your machine.
