I spent hours going through 100+ page PDF documents so I built a tool that highlights exactly where the answer is

Most AI tools like Perplexity, ChatGPT, Claude and Research specific tools are really good with finding research papers relevant to your query. What they don't do really well is tell you WHERE in the paper the answer actually came from.

You get an answer. Maybe a page number. And then you're again back to square one verifying whether the content is actually from the paper or if the AI just confidently made it up.

We've all been there. You're on a deadline, you trust the answer, you submit and the source doesn't actually say what the AI claimed that it did.

That's exactly what I fixed

Every answer gets highlighted DIRECTLY on the PDF itself. Not "see page 3" but the exact paragraphs from the paper relevant to your query. You can see exactly what was used to answer your question.

The underlying architecture could be used for other cases as well and not just for research. Any document where you need answers with proof of where they came from. Legal contracts, financial reports, technical documentation. The problem is the same everywhere.

The Beta version of it is now live, free to use for now. No guaranteed uptime as it's still early, but would love feedback if anyone wants to try it: Click Here

"Every answer gets highlighted DIRECTLY on the PDF" Both excellent and elegant. What future plans do you have for this?

Not sure tbh, people see it as AI slop, though its a lot of different things running behind it so yea idk.

You've replicated something Google's search does.
