Obooko
Hey HN, I'm George. I spent few months rebuilding Obooko, a free ebook platform that's been around since 2010 with 11 million downloads. Reading is losing to scrolling, but BookTok has 370B+ views. People want book content, they're just not reading books. I think that’s because modern reading hasn’t kept up with the pace of the internet. What I built Obooko is ad-supported like YouTube. No paywall, no subscription, no account required. 4,000+ books across 30+ genres. You can read in the browser, sync across devices, or download as PDF/EPUB/Kindle. The reader is built on EPUB.js…
Obooko launched on February 7, 2026 with 269 votes, #97 of 16,627 launches that month and more than 99% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
Obooko is a free reading platform offering thousands of books across 30 genres that can be read instantly in a browser, synced across devices, or downloaded as PDF, EPUB, or Kindle files. The platform features titles from independent authors and New York Times bestsellers with no subscriptions or proprietary formats. It operates on an ad-supported model similar to YouTube, allowing readers free access while enabling authors to earn revenue. The service is designed to increase overall reading engagement.

- ISI scraped 3B Goodreads reviews to train a better recommendation modelNov 2025 · book.sv · ▲606
Hi everyone, For the past couple months I've been working on a website with two main features: - https://book.sv - put in a list of books and get recommendations on what to read next from a model trained on over a billion reviews - https://book.sv/intersect - put in a list of books and find the users on Goodreads who have read them all (if you don't want to be included in these results, you can opt-out here: https://book.sv/remove-my-data) Technical info available here: https://book.sv/how-it-works Note 1: If you only provide one or two…
I built a tool to help you read Hacker News on Kindle2022 · ktool.io · ▲393Hi HN, I'm Daniel Nguyen. In June, I quit my job to start indie hacking full-time. The idea of KTool first came to my mind when I was reading "Ask HN: I'm a software engineer going blind, how should I prepare?"[0] I've been wearing glasses since I was 5. My right eye is basically blind. Doctors said there is no chance to cure it. I was genuinely scared. Like holy shit, if my left eye stops working, my life is done. Since then I've been very conscious about time spent on computer screens. That's when I started using Kindle-related products: to offload as many reading materials as possible to…
I mapped HN's favorite books with GPT-4o2024 · hnbooks.pieterma.es · ▲285Hey HN! I love finding new books to read on here. I wanted to gather the most mentioned books and recreate the serendipity of physical browsing. I scraped 20k comments from HN threads related to reading, extracted the references and opinions using GPT-4o mini, and visualised their embeddings as a map. - OpenAI's embeddings were processed using UMAP and HDBSCAN. A direct 2D projection from the text embeddings didn't yield visually interesting results. Instead, HDBSCAN is first applied on a high-dimensional projection. Those clusters tend to correspond to different genres. The genre…
I generated 70k audiobooks with OpenAI Text-to-Speech2024 · listenly.io · ▲140Hey HN. I’m Ivan, hacker from Ukraine. For about a year, I was working on Listenly — an app to listen to text content with OpenAI's natural-sounding text-to-speech model. At some moment, I realized that it would be cool to take all the public domain e-books and create audio versions for them. So I did it... kind-of. It would cost an immense amount of money to generate all the audio right away (OpenAI TTS costs approximately $0.84/hour of audio; 11labs, for comparison, is 10 times more expensive). So, I took a more gradual approach. I took all the metadata from the Project Gutenberg…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
