The Alexandria Index

Massive internet datasets, embedded, open-sourced and free

The Alexandria Index launched on May 27, 2023 with 137 votes, #305 of 4,910 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 3 years on.

What it does

Vector embeddings are incredibly powerful, compressing text into a low-dimensional 'meaning space', but they're also shockingly cheap. Alexandria is an open-source project to embed and release (for free) large datasets in research, law, medicine and more.

From barbarism to civilization requires a century; from civilization to barbarism needs but a day.

Help support our initiative by building with our datasets, voting on what you want next, spreading the word about the project, or even donating to help us in our mission to embed the internet. If you’re interested in our work or want to contribute, get in touch! PS. Are you a vector database company? Want the future to be built on your platform?

    I made a website to semantically search ArXiv papers2024 · papermatch.mitanshu.tech · ▲324

    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…

    OSS AI agent that indexes and searches the Epstein filesJan 2026 · epstein.trynia.ai · ▲211

    Hi HN, I built an open-source AI agent that has already indexed and can search the entire Epstein files, roughly 100M words of publicly released documents. The goal was simple: make a large, messy corpus of PDFs and text files immediately searchable in a precise way, without relying on keyword search or bloated prompts. What it does: - The full dataset is already indexed - You can ask natural language questions - Answers are grounded and include direct references to source documents - Supports both exact text lookup and semantic search Discussion around these files is often fragmented. This…

    Hey HN, we're happy to release Mycelium, a JavaScript library for creating graph visualizations of machine learning models or any other directed acyclic graphs. Mycelium powers the graph viewer of the Talaria [0] a research model visualization and optimization system, which was used to optimize the efficiency of Apple Foundation Models [1]. Everything works entirely on the client-side in the browser — we provide a rudimentary ONNX loader out of the box, which you can try by dragging model files into our website. It is also simple to define loaders for your own model formats. The library was…
