FAQPage Schema

How do I index a directory of documents into a structured concept map?▼

To index a directory of documents into a structured concept map, point the tool to your target folder. It reads the files, uses Gemini by default, and generates a searchable knowledge graph with source references.

What is a reference-backed concept map for research notes?▼

A reference-backed concept map is a structured knowledge graph that links concepts to their original source documents. It helps navigate large research collections by preserving citations for each indexed section.

Can I index large document collections if Gemini is unavailable?▼

Yes, you can index large document collections if Gemini is unavailable. The tool automatically falls back to a secondary LLM to ensure your directory is still processed into a structured concept map.

Does this tool preserve source citations when generating a knowledge graph?▼

Yes, the tool preserves source citations when generating a knowledge graph. It attaches explicit source references to concepts and sections, ensuring full traceability across your indexed directories.

What files do I need to set up before indexing a knowledge base?▼

You need a target directory containing your documents. The tool reads this folder and automatically writes input-history.md and prompt.md files to process your knowledge base into a concept map.
