Upload documents

PPTX, PDF, DOCX, XLSX, CSV, Markdown, TXT, JSON. The tier sets which source wins when documents disagree.

Rebuilds the index from every uploaded document: focused chunks, keyword + meaning search, and AI-generated questions for each passage so everyday and cross-language questions find the right source. New uploads are expanded automatically; run this after changing many documents. Takes several minutes; Nabd stays available.
