I built a tool to help you read Hacker News on Kindle
Hi 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 built a tool to help you read Hacker News on Kindle launched on August 29, 2022 with 393 votes, #40 of 3,307 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 4 years on.
In plain words
KTool is a service that converts online content to Kindle-compatible formats, allowing users to read Hacker News discussions, blog posts, Twitter threads, RSS feeds, and newsletters on e-readers. Designed for people who want to reduce screen time, the tool sends various web content directly to Kindle devices. It addresses limitations in existing services by supporting multiple content types in a single platform.

Amazon now requires every complete sender email address to be approved individually. Because this public tool does not use a signed-in KTool account, we can no longer offer reliable direct Kindle delivery here. Sign in to KTool to find your unique sender email address and set up Kindle delivery. As a regular HN reader, I know that some of the most interesting content is in the comment section, not necessarily in the article itself. It would be great if I could read the entire discussion offline, on a comfortable e-ink screen. I tried my best to keep the same styles as the original HN page. [...] I cant wait to try it. Just need to send a discussion I am really interested in, happens every…from ktool.io

HN to E-Book – Read HN on your E-Reader2022 · github.com · ▲86I read HN on my kindle as I find it useful for reading under sun(while walking in a controlled environment) and taking notes. I was running hntokindle.com to offer this as a service for others. But Amazon has recently made sending bulk emails to the Kindle impossible by requiring 2FA over registered Amazon email address for each item sent to the Kindle. Hence I've stripped down HN to Kindle code to enable local transfer to any e-book reader which supports .mobi format and made the project open-source.

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
