24 alternatives to Related Website Finder Experiment Thingy
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.
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Related Website Finder Experiment Thingy launched in 2022; newer entries below may have overtaken it.

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…

Hey there HN! We’re Antonio, Luca, and Yuhang, and we’re excited to introduce Fast GraphRAG, an open-source RAG approach that leverages knowledge graphs and the 25 years old PageRank for better information retrieval and reasoning. Building a good RAG pipeline these days takes a lot of manual optimizations. Most engineers intuitively start from naive RAG: throw everything in a vector database and hope that semantic search is powerful enough. This can work for use cases where accuracy isn’t too important and hallucinations are tolerable, but it doesn’t work for more difficult queries that…

Browser Buddy▲156Hey HN, thank you for being a part of the internet we love. We’re Arnav, Mo, Jeremy and we’re building an “Internet for-you page” that recommends blogs and essays based on your interests. Try it here (https://www.browserbuddy.com/)! We love to discover and learn from personal blogs, essays, and articles on the internet. But despite exciting advancements in language modeling, it’s felt harder to discover interesting links from real people. We believe there is untapped potential to use these language models as “curators” rather than “creators”. To explore this, we’re building a…

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…

We built Valohai LLM for tracking and comparing LLM evaluation results. Whether your evals live in notebooks and spreadsheets, or you're using an observability tool that wasn't built for comparison, this gives you a purpose-built eval comparison dashboard. Run evals with a Python library (pip install valohai-llm), results stream in, and you can compare up to 6 configurations side by side. Group by any dimension (model, category, difficulty) to see where each model excels. It doesn't do tracing or production observability, for now just eval tracking and comparison. What's cool is that you can…

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.

I recently found myself computing the similarity between lots of very high dimensional vectors (i.e., sentence embedding vectors from LLMs), and I wanted to try some more powerful measures of similarity/dependency than just Cosine similarity, which seems to be the default for everything nowadays because of its computational efficiency. There are many other more involved measures that can detect more subtle relationships, but the problem is that some of them are quite slow to compute, especially if you're trying to do it in Python. For my favorite measure of statistical dependency,…

Trails▲81Hey 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 website with my wife in mind; it makes it possible to browse for similar fashion products over many different retailers at once. The backend is written in Swift, and is hosted on a single Mac Mini. It performs nearest neighbors on the GPU over ~3M product images. No vector DB, just pure matrix multiplications. Since we aren't just doing approximate nearest neighbors but rather sorting all results by distance, it's possible to show different "variety" levels by changing the stride over the sorted search results. Nearest neighbors are computed in a latent vector space. The model…

I've open-sourced the script I use to find related blog posts (and to describe why they're similar). Works on any set of markdown articles, so should fit into any SSG workflow. Uses embeddings to calculate the similarities, and GPT4 to add descriptive text.

Hi! Long time reader, first time submitter. I've finallllyy got my first webapp online. It's been a long time coming, I started it over a year ago and just been an hour here, a couple of hours here, and a period of a couple of months of nothing. I first wrote it as a way to learn some python it sort of grew to fill a need I had. It's at a point now where I'd LOVE some feedback as I am going round in circules. Please, it's free, just hit the home page, plugin in a name/email and url you want to links checked on. If you use the name 'DeleteMe' I will remove the account after a week, so feel…

Hey folks, There has been some talk about search engines here so I thought maybe I'd share a new project I'm working on. Built it partly to help me sell my own projects. Still a lot of work to be done but would be happy to get feedback. Very early phase so don't trust your life with it. Cheers --- Edit: if anyone needs a free/no CC account just DM me on https://www.linkedin.com/in/crufter/

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,…

In an effort to understand it, I put together a simple, pure python implementation of HNSW, an approximate nearest neighbor library. Learned a lot, and I think for anyone interested in vector search it's an exercise that's absolutely worth doing. The code is optimized (imo) for readability, and working (albeit, quite slowly) on putting together a tutorial that walks through the motivation and implementation of HNSW. There's also working code examples for using the library for text and image search with sentence transformers and CLIP!

Hey HN Community! We built this simple community search tool that basically allows people to search through thousands of past Reddit threads and tens of thousands of recommendations using tags. It mostly covers a few bigger subreddits like r/BIFL, r/MFA, r/AskMen, r/SkincareAddiction but along the way, I expanded it to include other smaller subreddits too. In addition to filtering by category, power users can also search by -Body Fit (big thigh, long torso) -Occupation (work in retail, teacher, doctor) -Age (18-24, 25-35), Size (height, weight) -Brand comparison (similar…

Jello SEO▲11I was watching Deep Research do hours of research in minutes and thought why the hell am I still manually clicking through Ahrefs trying to guess what keywords to check? So I built an AI that does keyword research the same way. The problem with traditional keyword tools is they assume you already know what to look for. But I'd sit there thinking "okay I'm building a developer tool... do I search for 'API monitoring'? 'webhook debugging'? 'API testing'?" Then I'd spend an hour going down rabbit holes and miss the fact that "Postman alternative open source" or something like that gets 2k…
