Extractium is a lean knowledge-base compiler. It crawls an organization's public sources (TeamDynamix client portal KB, GitHub org, YouTube channel, generic websites, local files), normalizes everything into one set of parent/child text chunks with embeddings and BM25 postings, then serializes that single chunk set into multiple output formats (a "compendium") suitable for static hosting on GitHub Pages.
It is the crawling/indexing engine extracted from FieldStationAI's build-kb-index.py, generalized behind a config file and a plugin registry so any research center or organization can produce its own compendium.
pip install -e ".[dev]"The extractium command is not yet functional (package-skeleton stage — see docs/extractium-spec.md for the roadmap).
