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 😄
I like the exact-line citations. Congrats!
@henry_habib Thanks Henry! Exact-line citations are one of my favorite parts too — we really want every answer to be easy to verify, not just sound convincing. Appreciate the support!
Really good product from popular opensource lib. Congrats on this launch!
@peng_wood Thank you! Happy to keep contributing to open source :)
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. 👋😄
Congrats! Avoiding embeddings is an ambitious architectural choice. I'm especially curious whether this makes the results more interpretable, since each search decision could potentially be traced through the document tree.
@william_wang24 Exactly — that’s one of the things we care about most. Because retrieval happens over the document structure rather than an embedding space, we can make the reasoning path much easier to inspect, and then ground the final answer back to the exact source lines. Thanks William!
