  A few weeks ago I realized i was spending way too much time trying to write quality posts for Twitter. So I decided to look into scheduling tools which could help me automate my writing. I tried a few, but none of them satisfied me. Either the interface was way too complicated or the features i wanted were just not there. Finally, after some time I gave up… and instead I decided to just do it! I hacked up a quick prototype in a weekend. Tried it out - it worked!! Mostly.. I fixed some bugs, made a nice UI, and now (3 weeks later) I think I built one of the nicest scheduling tools out there.

  Heya HN, I've been working on a vibe-marketing platform as my primary side project for the last few months. Doing a (very) soft launch today, mainly because I want to use it to challenge how we think about AI-generated content (Some people call it SLOP - bear with me). How PostKing works: I create a statistical model of your existing content - blogs, social posts, university assignment anything you've written. It learns your brand voice, tone, and positioning - not just surface-level writing style, but the actual way you think Generate content across any channel that sounds authentically…

  Hi HN, I've been using LLMs to help draft replies and content, but I hit a wall: the "default" voice of standard models is painfully obvious. It’s always too cheerful, uses emojis incorrectly, and loves words like "delve" and "testament." I realized I was spending more time editing the AI's output to sound like me than it would take to just write the thing myself. So I built PostOwl to solve the "Style Alignment" problem. How it works: Instead of a generic wrapper, it uses your previous posting history to build a style profile. When you generate a reply, it dynamically injects your specific…

  Hello HN, I’m the creator of Post2X. I recently left a 7-year career in Data Science and started to build my own tool. The problem I faced was tool fragmentation. To do content marketing on social media, I was context-switching between LLMs for copy, meme databases for visuals, and Buffer for scheduling. It was inefficient. I built Post2X to unify this entire stack into one flow. My internal benchmark is to create and schedule 100+ posts in under 1 hour, allowing me to batch my content marketing work and get back to coding. How the workflow achieves that speed: * Unified Drafting (Voice &…

  I got tired of spending 30+ minutes just to publish one post across platforms. Writing separate captions. Downloading Canva designs. Switching tabs to check previews. Uploading everything manually — every single time. So I built a tool to fix that. It lets you: - Connect IG, TikTok, X, YouTube, Facebook, and LinkedIn - Pull designs directly from Canva (or upload media manually) - Auto-generate platform-specific captions using AI (based on your brand voice and uploaded media) - Preview how each post will look on each platform - Schedule or publish everything in one go The AI captions were the…

  I spent 6 years building a ridiculous wooden pixel display▲1,145

  I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

  I was curious about spherical helix, ended up making this visualization▲865

  I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

  The current sky at your approximate location, as a CSS gradient▲788

  For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
