24 alternatives to An AI zettelkasten that extracts ideas from articles, videos, and PDFs
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…

Hey everyone, I wanted to share a new tool we've created called Jotte (https://jotte.ai) which we believe can be a game-changer for AI-generated longform writing like novels and research papers. As you may know, current AI like ChatGPT and GPT-3 have a token limit of around 4000 tokens or 3000 words, which limits their effectiveness for longer writing tasks. With Jotte, we've developed a graph-based approach to summarize information and effectively give AI "unlimited" memory. Jotte remembers recent details like the meal a character ate a page ago, while avoiding getting bogged down…

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...

Gistr▲55Hey HN, We (a small team of engineers and a designer) have been building Gistr to solve a personal pain point: we consume a lot of content daily—articles, videos, podcasts—and often struggle to retain or revisit the most meaningful parts. Most bookmarking tools felt too passive or generic. So we made Gistr a tool that lets you save links and capture "gists" (notes, insights, highlights, AI summaries) on top of them. It supports YouTube, articles, PDFs, and more. You can keep things private or share your gists publicly, almost like AI-enhanced social bookmarks. We’re bootstrapped and still in…

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…

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…

While summarizing videos (I'm the Eightify founder), I've been secretly working on an AI-generated encyclopedia, and here's why. I found myself thinking a lot about AI and content. Now we have knowledge (think Wikipedia) and intelligence (LLMs). They will both significantly improve soon. What we lack is *a knowledge interface for humans*. What I don't like about current interfaces: - ChatGPT: to get an answer how I want it, I need to craft a perfect prompt - Google: need to spend time avoiding affiliates and unreliable sources - Wiki: great, but boring to read, too much information What I…
