@yura_acti Exactly. That’s the philosophy behind PageIndex — AI should help you navigate and understand the document, while the original source stays one click away for verification. Thanks for calling this out!
Great use case at the core of the project! I often check contracts with ChatGPT the same way when I need to quickly find payment terms or deadlines.
This seems especially valuable for investors and researchers.
@s_cen Absolutely, those are two of the core use cases we had, especially when you’re working across long reports and filings and need to verify everything back to the source line.
Super useful tool. Congrats Mingtian and team. Does PageIndex tell me which version it pulled from? Data rooms I read usually have the same number living in three versions of the same file - original, amended, restated.
@tmaleh_ Of course, Taissa! For every number PageIndex gives you, you can see exactly which document and version it came from, then jump straight to the cited source line. You’re more than welcome to try PageIndex on your data room!
what is the latency for this kind of search?
@yilu Thanks for asking, Yi. In PageIndex's approach, the documents need to be pre-processed once to generate a tree structure, which is slower than the vector-based method. However, during retrieval, this approach only requires the LLM to condition on the context and does not require an embedding model to convert the query into vectors. As a result, it can be efficient when the tree is small. When the tree is large, it may be slower than the vector-based method, since it prioritizes accuracy. For documents where a wrong number costs a lot more than a few extra seconds, that's the trade we picked.
Love that I don't have to keep scrolling through a 500-page PDF anymore！
@lantian Haha yes, that’s one of the best parts 😄
the one click jump back to the exact source line is the killer peice 🙌 nice work
Looks like a life changer. How well can it handle unusual documents like textbooks is going to be nice to see. 👋😄
