# Tool: Big Words Source: [https://simonwillison.net/2026/May/7/big-words/](https://simonwillison.net/2026/May/7/big-words/) 7th May 2026 Tool[Big Words](https://tools.simonwillison.net/big-words) I'm using my[vibe coded macOS presentations tool](https://simonwillison.net/2026/Feb/25/present/)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](https://github.com/simonw/tools/pull/279)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](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.](https://static.simonwillison.net/static/2026/big-words.jpg) Posted[7th May 2026](https://simonwillison.net/2026/May/7/)at 6:47 pm
