Tool Big Words

I'm using my vibe coded macOS presentations tool to put together a talk, and I wanted to add a slide with some text on it. The tool only accepts URLs, so I put together a quick page that accepts query string arguments and turns them into a simple slide.

Here's an example: https://tools.simonwillison.net/big-words?text=simonwillison.net&gradient=1&size=9.5

Double click or double tap the page to access a form for modifying the different options.

Screenshot of a slide editing tool showing a slide on the left with "simonwillison.net" in heavy white sans-serif text on a black-to-blue gradient background, and a "Slide settings" panel on the right with: TEXT field containing "simonwillison.net", TEXT COLOR white, BACKGROUND black, "Use gradient background" checked, SECOND COLOR blue, ANGLE 135°, FONT "System sans-seri", WEIGHT "Heavy", SIZE 9.5vmin, unchecked Italic / Uppercase / Drop shadow checkboxes, and Reset and Save URL buttons.

This is a beat by Simon Willison, posted on 7th May 2026.
