Understanding scientific articles can be tough, even in your own field. Trying to comprehend articles from others? Good luck. Enter, Now I Get It! I made this app for curious people. Simply upload an article and after a few minutes you'll have an interactive web page showcasing the highlights. Generated pages are stored in the cloud and can be viewed from a gallery. Now I Get It! uses the best LLMs out there, which means the app will improve as AI improves. Free for now - it's capped at 20 articles per day so I don't burn cash. A few things I (and maybe you will) find interesting: * This is…

heyo! Explainpaper lets you upload a research paper PDF. If you don't understand a formula or sentence, just highlight it and the tool explains it for you I built this a few weeks ago to help me read a neuroscience paper, and it works pretty well! I didn't fine-tune GPT-3, but I do take a lot of context from the paper and feed that into the prompt (not the whole paper). Ppl have uploaded AI, biology, economics, philosophy papers and even law documents. Works in Chinese, Japanese, Spanish, French and more as well!

I’ve been frustrated with PDFs and found arXiv HTML lacking, so I built a fully interactive paper reader. Features: • Hover references, citations, equations • Light/dark mode • Auto-generated dependency graphs for definitions/lemmas/theorems • Table of contents that syncs with scroll • Highlighting + annotations • “Copy raw LaTeX” anywhere Featured paper: Video models are zero-shot learners and reasoners (Veo 3) https://www.sciencestack.ai/arxiv/2509.20328v2

My wife recently started her PhD and while she uses Zotero as a citation manager, she was really missing a tool for keeping track of what she's reading right now/has already read/needs to read next. This overwhelming experience might be familiar to other researchers working on a niche field where every paper is called pretty much the same thing So I built her Paperstack. It's basically Goodreads, but for research papers: - Save articles to familiar To Read/Reading/Read stacks - Tag articles with logical projects/chapters/whatever your system is - Get…

Hey HN, I built a PDF reader that can generate interactive visualizations right inside the document. The goal is to reduce the “intuition gap” when reading dense papers: select a concept, click Visualize, and it tries to produce a solid visual interactive app where you can rotate/zoom/step through (not just a text explanation). Upload any PDF, select text, click Visualize. Demo (no signup): https://zerodistract.com/try/pdf/67cdee74-810b-4f1b-af7d-010... Product link: https://zerodistract.com I’d love feedback, especially on what feels useful vs.…

ResearchPRO is Notion-Chrome Extension that allows you to do two things: (1) Create and categorize web-highlights on any website or pdf and sync them in real-time into Notion. With buckets, and the SHIFT SHIFT shortcut, you can do this all on the fly. Defining a new bucket or category, creates a toggleable lists of grouped highlights in the Notion page of your choosing, which allows you to keep track of ideas and references across different articles. (2) Export bibliographies for a given research “topic.” Of course this just allows you to bucket links related to a given topic, if you need to…
