What is PageIndex?

PageIndex answers questions across long professional documents and, crucially, lets you jump straight to the exact source passage behind every answer. It is built for dense material like reports, filings and contracts where verifying the citation matters as much as the answer.

Pros: what PageIndex does well

  • Every answer links to the exact source
  • Built for very long documents

Cons: where it falls short

  • Most useful on text-heavy professional material

Who PageIndex is for

Anyone who reads long reports and needs verifiable answers fast.

Who can skip it

People working with short, simple documents.
