PaperLens

Hey HN, I built PaperLens ([thepaperlens.com](https://thepaperlens.com/)) after one too many frustrating sessions trying to find what I actually needed in academic research. Whether I was doing a literature review, trying to quickly find a solid source to back up a point in a discussion, or just attempting to understand a complex subject, traditional keyword searches often felt like searching for a needle in a haystack. PaperLens uses RAG (Retrieval-Augmented Generation) and the latest AI models to provide more precise, semantic search results. It also has an AI chatbot that…

PaperLens launched on January 2, 2025 with 11 votes, #1,388 of 6,141 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 1 year on.

    Hi HN! Open Paper allows you to annotate and understand your research papers with an AI copilot. I wanted a paper-reading assistant that let met actually dig into papers in-place while benefiting from AI tooling. When it comes to studying, I'm not a fan of the typical chat interfaces that obfuscate uploaded files and turn them into black box 'content'. Hence, I've implemented a split-pane view. To mitigate the risk of hallucinations, all AI responses come with grounded citations that refer back to the source material in-flow. Some feature highlights: - Actually read your papers in one place…

    I made a website to semantically search ArXiv papers2024 · papermatch.mitanshu.tech · ▲324

    As a grad student (and an ADHDer), I had trouble doing literature review systematically. To combat this, I made a website that finds similar papers using the meaning of the thing I am looking for. I used MixedBread's [^1] embedding model to generate vectors from the abstracts. I store and search similar vectors using Milvus [^2] and finally use Gradio [^3] to serve the frontend. I update the vector database weekly by pulling the metadata dataset from Kaggle [^4]. To speed up the search process on my free oracle instance, I binarise the embeddings and use Hamming distance as a metric. I would…

    I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

    I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
