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…

Just go to the link and click on "Start Creating". No signing in required. I built shortbread to help anyone to create comics / manga series. The onboarding process helps you kick start a page from 60%, then you can use your creativity to bring it to 1000% in a fully-controllable editor. Tech stack: GPT 3.5 Turbo - the comic script generation. It handled everything from layout, character, scene, SD prompts, to dialogue. SD 1.5 - We put up SD servers on GCP. For every comic we generate one large image and crop it into panels. Per the experiments of u/Deathmarkedadc on Reddit, this…

TL;DR: private, in-browser converter that turns pretty much any image file format into standard JPEGs. Everything runs locally. No uploads. This started as a five-minute job and forty hours later... I wanted to convert a HEIC without uploading it anywhere, so I wrestled Emscripten/WebAssembly to run Google's Jpegli inside a Web Worker. Now there's a small UI and it handles a bunch of formats. Just about the only thing it can't decode is JXL - but there's still some JPEG XL magic in there: XYB perceptual color quantization is enabled by default via Jpegli. The upside of all this…

Hey HN, I built an SDK to help me create apps I wanted on my Kobo. My Kobo device has a single core <1GHz processor and 512MB RAM, much less than a Raspberry Pi, but the eInk display and larger battery life opens up a lot of use cases. I have since used it to build an approval sidekick for my Mac's Claude code and codex, a Hacker News Client for Kobo, a Gutenberg reader, an RSS search and reader and more. All the code is in the repo. If you have a different device than mine (Clara BW) would love for you to test it on your device and submit a PR to enable this for more device profiles. Thanks.
