FAQ
Frequently asked questions
- How is ContactGraph different from Notwork?
- Both aim to improve professional networking. ContactGraph focuses on searching and enriching the contacts you already have, then matching them to open jobs — rather than building a new social network from scratch.
- Does ContactGraph work with AI agents?
- Yes. ContactGraph runs as an MCP server, so AI agents like Claude, ChatGPT, and Gemini can query your network directly. It also provides a skill.md for terminal-based agents.
- Can I self-host ContactGraph?
- Yes. The entire codebase is open source on GitHub. You can run your own instance or use the free hosted version at contactgraph.ai.
- What does the enrichment process look like?
- After you upload your contacts, ContactGraph uses public web data to fill in current employer, role, and industry for each contact — including people you haven't spoken to in years.
