Up until now, I've always used PowerPoint for my talks: WYSIWYG, can get something decent just by dragging a few elements around. However it quickly becomes a nightmare when dealing with animations or complex layouts.

For the preparation of my next talk, I wanted to be able to use AI to brainstorm ideas, and stop wasting so much time fighting with PowerPoint. But editing pptx files is challenging, so I decided to give @sli.dev a try, and switch to an agent-first workflow: I describe what I want, the AI does it.

At first I had mixed results. It was great to tell the AI my ideas, have it build a mockup, and then use it as inspiration for the final slide. But the AI always got A LOT of details wrong, especially on alignment and sizing, and iterating on those details wasted all the time that I initially saved.

The breakthrough came when I installed the Claude Chrome extension. At my next design session, Claude started using it to check the result and iterate on its own to fix all the alignment issues. Now we finish a slide in just a couple prompts, where it easily took 3 or 4 times more before.
