edgextract

edgextract is a browser tool that turns markdown into a knowledge graph using a custom ontology and decision model.

Edgextract is a browser-based tool compiled to WebAssembly that converts markdown text into a knowledge graph. Users provide their own ontology and define a cutoff threshold to control graph generation. The system processes text using a specified decision model, such as the default Tev1 model running locally via WebGPU, ensuring data stays on the device. Every name and link is treated as a closed question answered by the model. It supports local browser execution and integrates with backends like Ollama. The tool is designed for users who want to build structured knowledge graphs from text entirely within their browser environment.
