Hey PH 👋 Mingtian here, founder of PageIndex.
A year ago, we set out to build AI that reads a document the way a human expert does: understand the structure, follow the evidence across pages, and cite the exact line.
Today, we’re launching PageIndex, bringing that technology into a simple browser-based workspace.
📄 1,000-page documents, with tables and charts actually understood.
📍 Every answer has a clickable reference to the exact line in the source.
🔁 Ask one question across several documents and compare them side by side.
🌐 Explore ready-made public knowledge spaces: SpaceX's IPO filings, Stanford CS229, the YC SAFEs, and more. Nothing to upload, just chat with one and feel the difference.
PageIndex achieved 98.7% accuracy on FinanceBench, a benchmark for answering questions about financial documents. Our open-source project has earned more than 34K GitHub stars, and over 30K cloud users already use PageIndex.
Who it's for: analysts reading filings, lawyers reading contracts, researchers reading papers. Anyone whose documents are too important to skim.
🎁 Product Hunt launch offer: use code PRODUCTHUNT to get 1 month of PageIndex Pro free. Limited to the first 100 users.
I'll be here all day, reading every comment.
