The problem
Good answers are already in the documents.
Engineers should not need to scan sixty-page vendor PDFs or pay a frontier model to reread thousands of pages for each question.
What was built
A catalog that keeps the evidence attached.
Factwin turns a document collection into a technical catalog: product names, specifications, and relationships are indexed once, then answers point back to the exact source page.
The working loop
Crawl, lift, answer, revise
The work moves through a tight loop: crawl the collection, lift the useful fields, answer real questions, and revise against the evidence.
