24 alternatives to Hexle: A powerful way to search for papers and connect your ideas
Hi all, I find literature searches to be slow and despite all the tools nowadays, it is difficult to map out vast areas of research and then connect my ideas to what I’m trying to do (e.g. writing a review, learning something new, planning a new project, assignments, etc). Some of my peers and teachers also found this to be a problem so I built this MVP app to help people not only leverage AI search capabilities but also go on to connect their ideas, map out research projects, cite various results and organise their “stream of consciousness” as they work. I’d love to get some feedback on it…

I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

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…

Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

Bibby AI ▲165Hi, Fellow researcher from Yale, I was frustrated with Overleaf and google docs not able to write and collaborate on documents the way I wanted to. I write my research in Latex but since Cursor came out, I thought this has to change, I'm wasting too much time and having mental fog all the time, kinda going through writer's block and hence I decided to create this latex writing assistant for myself but now used by a ton of researchers, I wanted your feedback, what you like, what you don't like, alternatives you've seen, what you would like to have, nice to have, you'd definitely pay to have,…

Open Paper▲289Hi 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…

Heuristica▲34Hi HN! I have built an AI-based content creation tool called Content Explorer. Instead of writing to create the best content, it allows you to iteratively discover it by offering a bunch of operators that modify and enhance your initial input. The node-based interface allows you to easily visualize the result of your operations and compare and contrast different versions. I like the mental model of Large Language Models as word calculators. So I have built this word editor that works like an image editor since we can now process language just like we have been processing images. You can use…

Almost one year ago I asked HN if anybody is interested to make a Web app to make reading and finding scientific papers smarter [http://news.ycombinator.com/item?id=1664648]. No one did, at least no one did what "I" think is the best way to approach this problem. A a few month ago I decided to do it myself.<p>Meet JournalClub iPad app (absolutely free), http://itunes.apple.com/us/app/journalclub/id443819334? I have a recommendation engine in the pipeline that I would introduce in the next update (hopefully in a month or so). I really appreciate any comments, feedbacks.

The Drive AI▲131After months of hard work, I'm thrilled to announce the launch of Chat Channels and Direct Messages on The Drive AI. Why Chat Channels? During my master’s program, managing extensive research, project discussions, and documents across platforms like Google Drive, Zotero, and Slack was a real challenge. Finding past discussions on Slack became harder as projects progressed, leading to inefficiencies and repeated questions. Imagine a platform where every research paper, project file, or document seamlessly integrates with persistent chat channels—a system that combines the best of document…

PaperLens▲11Hey 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…

Over the past year, we’ve been frustrated with how clunky it is to manage research papers. So we built Ontosyn, a modern research paper reader, with clean ui, better in paper navigation (bookmarks, jumping back up after clicking on a reference), an integrated ai chat with useful tools such as recommending relevant papers that you can directly add to your library, and, of course, library functionality to keep everything organized. We launched a closed alpha last week, and our first users are quite pleased with it. One user asked for author-based search for paper recommendations yesterday, and…

I saw this app youlearn.ai on YC and thought of building it. They are claiming to have 1M+ users with just one feature which is to convert your learning material into summaries, quizzes etc. I gave this a shot and cloned almost most of the features in just 9+ hours of continous vibe coding (with 20% manual though). Now I'm selling this on mvp marketplace. Might probably open source it in future or give it free.

I built an AI-powered research agent designed to efficiently discover, summarize, and cite relevant academic papers based on user queries. As a university student, I've written my share of essays and have also served as a copy editor for our student newspaper. During fact-checking, I noticed that Google often prioritizes unreliable and unscholarly resources—such as Medium articles, Reddit posts, and LinkedIn content—in its top results over scholarly ones. For instance, searching "Transformers" yields six blogs and articles before finally listing the Vaswani (2017) paper. This makes gathering…

Hey HN! Over the weekend (leaning heavily on Opus 4.5) I wrote Jargon - an AI-managed zettelkasten that reads articles, papers, and YouTube videos, extracts the key ideas, and automatically links related concepts together. Demo video: https://youtu.be/W7ejMqZ6EUQ Repo: https://github.com/schoblaska/jargon You can paste an article, PDF link, or YouTube video to parse, or ask questions directly and it'll find its own content. Sources get summarized, broken into insight cards, and embedded for semantic search. Similar ideas automatically cluster together. Each…
