Some of this has previously been available in a somewhat inaccessible format. I've recently been working on a redesign of the marginalia search website.

I've been a bit obsessed with the idea of flipping through the internet a bit like you would a magazine, of undirected browsing as a discovery mechanism, and I think I'm approaching something that's beginning to feel pretty fun. The link at the top will return results out of a pool of approximately 10,000 domains, you can refresh to get new ones. You can also explore in a directed fashion by using the 'Similar Domains'-buttons. These are not random. A sampler, beyond the random sites offered with the head link https://search.marginalia.nu/explore/www.amiga-news.de…

I built Yourabbit.com — a site that curates hand-picked YouTube rabbit holes grouped by themes like quirky psychology, obscure tech, weird facts, and binge-worthy oddities. It’s not driven by the YouTube algorithm — every collection is themed and curated manually (for now), with a backend I’m automating to fetch and organize new rabbit holes daily. Built as a hybrid Astro + Next.js project, optimized for static generation and speed. I’m also pairing videos with custom summaries and commentary (using AI), and would love feedback from the HN crowd on: Content model (too wide? not specific…

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...

Been messing with cosine similarity and decided to try calculating nearest neighbors over the entire link graph for the marginalia search engine. Turns out that you can just bruteforce that in a day or two. And the results are pretty good. One drawback is that depending on if you're looking at an older website, a lot of the links are dead. The deduplication isn't great either.

Built a way to spatially explore wikipedia topics! Enter a topic of your choice and dig into the rabbit hole. All content is from Wikipedia—related topics are generated with GPT based on the summary. Spacebar to expand a topic inline, arrow keys to move around, and "J" to open journey view!

Hi HN! This started late last year as an afternoon project to play around with ElasticSearch, and then I kept thinking of new features I wanted to add. I still have a lot of things I want to build, but now seemed like a good time to put it out there: even if the results aren’t nearly the quality I’d like, I’ve still found it useful and I want to show it off! I’ve been working on it since September 2021, but only in fits and starts. The entire thing runs on a computer in my living room (there’s a picture on the About page); I haven’t done any load testing so we’ll see how it holds up.

Hi HN, I’m pleased to release my “surf engine” to the public for you to try. This is might be for you if you’ve grown frustrated with commercialised SERPs, and want to find the other websites are (still) out there. Kudos to Marginalia Search for showing that it’s possible to build a search engine as a hobbyist: https://search.marginalia.nu/ Feedback of all kinds very welcome! Ali

This was more of a sandbox to play with Raphael and Flot than anything else but I think there are some interesting statistics in there. It'd be awesome to do this over time but I really don't have the spare time required.

A little while ago I built an automated website that finds free stuff while filtering out scams. It works in an interesting way. Most freebie sites on the web contain a mix of real, useful free stuff and scammy affiliate and pyramid schemes. I realized that affiliate links are always unique (because they need to contain an affiliate code) while real freebies have URLs that co-occur across multiple sites at roughly the same time. I wrote a crawler in Perl and MySQL that looks for repeating, off-domain URLs that temporally cluster on multiple free stuff sites. I was surprised and pleased to…

Hello HN! I've been working on http://underthesite.com for the last month and now think it is ready for some full strength HN feedback. What do you guys think? It crawls up to 10 pages of a given site while you wait, looking for community-provided CSS / XPath selectors and regular expressions. Additionally, I'd like to appeal to you to submit matchers for technologies that you care about. Technologies are easy to add, so add your favorite jQuery plugins, analytics tools, client-side node.js wrappers, what have you. I'm going to be running a large crawl in the next few days and want to make…

Hey everyone! I’m excited to announce the release of my last project, MiniSearch. I admire Perplexity.ai, Phind.com, You.com, Bing, Bard and all these search engines integrated with AI chatbots. And as a curious developer, I took the chance and created my own version. Using Web-LLM and Transformers.js to provide browser-based text-generation models on desktop and mobile, I built a minimalist self-hosted search app on which an AI analyses the results, comments on them and responds to your query summarising the info. In the backend, it still queries a real search engine, but besides that,…

I decided to cut all the other features and just release the startup I have been working on for the last few months. http://seekier.com I hate to put it like this, but look at it as a twitter for sharing what you search. Seekier lets you see what others are searching, allows you to share your own searches, and discover more through discussion. Please let me know what you think of the idea and concept. There may be bugs because I decided to just release it. Thanks! If you decide to register, be great if you posted your profile.

Hey all, Justin here. I previously built Phind, the AI search engine for developers. One of the biggest problems we had there was figuring out what went wrong with bad searches. We had tons of searches per day, but less than 1% of users gave any explicit feedback. So we were either manually digging through searches or making general system improvements and hoping they helped. This problem gets harder with agents. Traces are longer and more complex. It takes more effort to review them, so I'm building a tool that lets you analyze LLM outputs directly to help developers of LLM apps and agents…

I made this classic looking text only search engine(sorry if that's overexaggerating) where you can get concise and straightforward results with sources. There are 5 prefixes right now. It is a prototype kinda thing right now. I am busy for my upcoming exams. So, I would appreciate if anyone is interested to contribute. I am currently using Gemini for this project. If anyone can implement better api's and improve code and the features it would be great help. It's generating fake source links right now, the search is slow, prefixes like weather and time needs to be fixed using api's related…

Hi there, I've created this side project to make it easier to find interesting repositories using AI. There's still a lot of work to be done to improve it, so any suggestions for enhancements would be greatly appreciated. Thank you!

I got the idea of [mindmap.so](http://mindmap.so/) out of my own frustration of managing my personal notes in Notion and Miro in parallel. I have built it 3 months back on top of excalidraw, posted it in Reddit a couple of times, and never looked back (was using it only for personal use). Little did I know that the small and nimble tool that I created has crossed 2000+ users (was so surprised when I saw the dashboard last week). It was all organic and word of mouth . Having 2000+ users trusting a product is no easy feat. That’s when I thought may be I should put some more…

I started this as a weekend project and posted it on HN 5 years ago. 300,000 users later, I just released v4 today. Octotree [1] gives GitHub a sidebar that improves file navigation and code/pull request review. Works on Chrome, Firefox, Opera and Safari. Any comment or feedback is appreciated.

Hi there, I've decided to jump on the AI train and put something together with low effort & high reward, to see if it can get any traction. What do you think? Is it a promising area? Do you guys have ideas for me? There is obviously going to be sea of LLM generated content out there and one project adding up to it might not necessarily be what world needs. In the same time there is something intriguing about the area. Well, please play with it and let me know what y'all think. Much appreciated.
