Little tools and experiments I've built with AI.

Some webtools I've built with Claude, Gemini and ChatGPT to automate tasks and fill gaps. Maybe they'll be useful for you too.

Do what you want with them, but I make no promises that they'll always work etc etc.

01

Tools

01.1No Acrobat Pro, no problem

PDF Joiner

Sometimes you need to stitch two or more PDFs together and don't have access to Acrobat, and don't want to upload your files to some random cloud service. This stitches them and does it all in the browser using pdf-lib.

01.2Experiment

Noise

An experiment to make a password generator from white noise

01.3In-browser MD export

MD to PDF

A full-featured, browser-based Markdown editor and converter that does everything locally.

01.4DWG / DXF

AeroCAD DWG Viewer

A simple DWG or DXF viewer for when you need to quickly check that what you've received is correct without having access to Vectorworks or AutoCAD. Set zoom, toggle layers and save to PDF or PNG.

01.5Event Things

PowerPoint notes to cue cards

This one is niche, but it takes the notes from PowerPoint slides and spits out a Word document formatted for different cue card sizes.

01.6Event Things

S⁴ — Simple Site-visit Slide Sorter

You're jetlagged, you've seen so many hotels they all blur into one, and now you need to do something with hundreds of photos in your camera roll.

Sort by date, day or location (if you share photos with location) and export to PPTX or PDF.
