Products that do what A little side project, a watercolor art generator does
Hi HN - this is a little side project I threw together. Some implementation details: image processing is all done with headless GIMP (running inside a Docker container) through its built-in Python API. It's _very_ slow (about 50 seconds/image), and currently it processes exactly one image at a time. The website is built with NextJS; payments are processed by Stripe. I've had the best results with pictures of houses, although certain photos of people or nature can look neat, too. (For example: https://brushify.art/s/ruYmQWk, original photo from…

Hey HN! I want to show my new open-source project ArtistAssistApp. ArtistAssistApp - the web app to paint better with ease. Tools for realistic color mixing based on real paints, tonal value drawing, simplified sketching, and more. Import your own photos, select any desired color directly from the image, and learn how to mix it with your paints. The web app provides a step-by-step guide on how to precisely mix that color using your own paints using atomic or optical mixing. Atomic mixing is the physical mixing of colors together, while optical mixing is the result of placing a transparent…

Hey HN! We're Ben and Izak, founders of Repaint (YC S23). Repaint is like Figma, but for creating real websites. It has panning, zooming, and dragging elements around. The settings closely follow html/css. We think an open canvas is a big improvement over other website builders. Everything is easier: styling, consistency, responsiveness… But making it work was hard! We thought HN would appreciate the tech behind it: - A custom WebGL rendering engine (w/text, shadows, blurs, gradients, & opacity groups) - A partial implementation of the css spec - A custom text editor & text shaper…

I'm excited to share my indie product, https://drawing.pics In this post, I'll share all the technical details behind it. So, what exactly is DrawingPics? It's an image-to-image and sketch-to-image generator that runs in a whiteboard, allowing you to draw your draft directly on the canvas and easily generate the desired image. How does it work from a technical perspective? TLDR: Miniconda + Diffusers + Electron + Excalidraw One of the most important aspects of creating this tool was finding a stable diffusion locally inference solution. There are many solutions available, such as…

Hi all, This is a generative art project I worked on over the past year or so consisting of about 100 little artworks generated using P5.js. I have an overview and technical write up here: https://dannyking.uk/artwork/colororbs You can play with my interactive demo and make your own here: https://dannyking.uk/artwork/colororbs/designer And the gallery is here: https://dannyking.uk/artwork/colororbs/gallery This project came about after reading a HN post about a year ago…

I was fascinated by this [0] and this video [1]. After many struggles, I finally built this app that traces images using circles similar to what these videos had shown. The most challenging part (to me) is to find a way to convert images to vector lines. I had tried Potrace, but its output is not suitable for my use case: too many small elements share the same border. Potrace's goal is to represent the original image faithfully using vector lines. But I want to trace the image edges. After searching and trying some Potrace alternatives in vain, I finally found my keyword. Surprisingly (to…

Painterly is an application that "paints" input images stroke by stroke to produce digital paintings. GenAI is not used in any part of the production pipeline. There is a free demo available under Releases on the GitHub repo. Let me know what you think!

Hey there Some time ago I built a site that generates AI pictures in a style of GitHub logo (https://octoart.vercel.app/). It's completely free, and even official GitHub accounts in Twitter and Instagram (yes turns out they have Instagram) posted about it. It was fun. So I thought it would be cool to build an app that works with any logo, so people can generate nice branded pictures with their logo. I went on to build https://logopictureai.com/. It's build with Next.js, Replicate API and Supabase. It's a very early version, I built it in a weekend. It works like…

I've been working on a CSS Sprite generator for a couple of weeks in my spare time. It uses HTML Canvas and JavaScript FileReader to open local images without any zipping or uploads, and tries to make the CSS generation as easy as possible. I made it because it is a tool that I wanted to have, and I am hoping to get some feedback from others now that it is functional. http://instantsprite.com

Hello HN! I want to share something me and a few friends have been working on for a while now — Zeroshot, a web tool that builds image classifiers using text-image models and autolabeling. What does this mean in practice? You can put together an image classifier in about 30 seconds that’s faster and more accurate than CLIP, but that you can deploy yourself however you’d like. It’s open source, commercially licensed, and doesn’t require you to pay anyone per API call. Here's a 2 minute video that shows it off: https://www.youtube.com/watch?v=S4R1gtmM-Lo How/why does it…

Hey HN I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions. So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy. What it does Convert images between JPG, PNG, WebP Works offline once loaded (PWA support) How it works It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices. Why I built it I wanted an instant, no-ads,…

Hi HN, I’ve been working on a side project: 4oimage.site — a fast, easy-to-use image generator that focuses on style-driven creation, not prompt engineering. Why I built this: I love generative AI, but most tools require carefully-crafted prompts or a deep understanding of models to get good results. I wanted to create something where you just pick a style, upload an image or input a concept, and get beautiful results — instantly. Key features: • Generate images in curated styles (anime, vintage, futuristic, watercolor, etc.) • No prompt tuning or parameter tweaking needed. • Clean UI, runs…
