Here's the new tool I built: https://til.simonwillison.net/tools/annotated-presentations - plus an animated GIF showing how it can be used
(I used ChatGPT extensively in building it, the prompts I used are included in my write-up of the tool)
I wrote about my process for publishing annotated versions of my talks - like https://simonwillison.net/2023/Aug/3/weird-world-of-llms/ - and shared a new tool I built to help with that progress, allowing me to OCR my slides for alt= attributes and type up annotations for them in Markdown

Discussion
I experimented with using Claude to clean up the YouTube transcript of my talk and turn it into text I could use in the annotated presentation - it did a pretty great job, though I ended up using just small portions and applying many of my own edits anyway
