simonw has vibe-coded 124 useful tools

Summary

Any time I share my collection of tools built using vibe coding and AI-assisted development (now at 124, here's the definitive list) someone will inevitably complain that they're mostly trivial. A lot of them are! Here's a list of some that I think are genuinely useful and worth highlighting: OCR PDFs and images directly in your browser. This is the tool that started the collection, and I still use it on a regular basis. You can open any PDF in it (even PDFs that are just scanned images with no embedded text) and it will extract out the text so you can copy-and-paste it. It uses PDF.js and Tesseract.js to do that entirely in the browser. I wrote about how I originally built that here. Annotated Presentation Creator - this one is so useful. I use it to turn talks that I've given into full annotated presentations, where each slide is accompanied by detailed notes. I have 29 blog entries like that now and most of them were written with the help of this tool. Here's how I built that, plus follow-up prompts I used to improve it. Image resize, crop, and quality comparison - I use this for every single image I post to my blog. It lets me drag (or paste) an image onto the page and then shows me a comparison of different sizes and quality settings, each of which I can download and then upload to my S3 bucket. I recently added a slightly janky but mobile-accessible cropping tool as well. Prompts. Social Media Card Cropper - this is an even more useful image tool. Bluesky, Twitter etc all benefit from a 2x1 aspect ratio "card" image. I built this custom tool for creating those - you can paste in an image and crop and zoom it to the right dimensions. I use this all the time. Prompts. SVG to JPEG/PNG - every time I publish an SVG of a pelican riding a bicycle I use this tool to turn that SVG into a JPEG or PNG. Prompts. Encrypt / decrypt message - I often run workshops where I want to distribute API keys to the workshop participants. This tool lets me encrypt a message with a pa...
