Self-hosted AI agents with a face, a voice and a memory: web, desktop (avatar overlay) and phone apps on one 21-stage pipeline.

Contextify is a document processing library that converts raw documents into AI-understandable context. It analyzes, restructures, and normalizes content so that language models can reason over documents with higher accuracy and consistency.

Crawl GitHub's AI repositories, authors and topics via the GitHub API and explore their relationships as an interactive 3D network graph (FastAPI + React).
