yggy

Most “chat with your data” tools take a shortcut: they chop up documents into chunks and hope a model can make sense of the mess. yggy is aiming at the part people usually skip. It turns cluttered documents and connected systems into a knowledge graph, without asking anyone to design a schema or run a pipeline first.

The pitch is simple enough to fit on the Product Hunt page, but the details matter. Every fact in the graph keeps its source, so the system can show where things came from instead of laundering everything into a blob of text. Duplicates are handled too: they merge automatically, and any merge can be undone.

That makes yggy less like a chat wrapper and more like a shared backend for knowledge. The same graph can be used by a team in the app, by code through an API, and by agents through MCP. That last part is the tell. This isn’t just for people asking questions in a browser.

It’s also hosted in the EU, with the promise that your knowledge stays yours. For teams tired of duct-taped data plumbing, that combination is the real hook: less setup, less guessing, and one source of truth that different tools can all tap into.
