Grounding AI Overview

Grounding converts PDF, EPUB, DOCX, and Markdown files into chunked Markdown with provenance hashes and FAISS embedding indexes. YAML-defined agents restrict searches to selected collections and can define personas. Use it for local document retrieval with Ollama or another local OpenAI-compatible server, without cloud APIs or telemetry.

Primary Use Cases for Grounding AI:
  • Index research papers and books for local question answering
  • Separate document collections by agent or subject
  • Retrieve source passages with page ranges and section headings
  • Automatically ingest files dropped into a staging folder
