I also shared four ChatGPT transcripts from sessions I used to help me cobble that annotated presentation together https://simonwillison.net/2023/Aug/6/annotated-presentations/#chatgpt-sessions
A particularly fun detail of the https://til.simonwillison.net/tools/annotated-presentations tool is how it uses Tesseract.js OCR (running in the browser) to extract suggested alt= text from the images
I wrote more about that in this TIL: https://til.simonwillison.net/javascript/tesseract-ocr-javascript
Discussion
Of those four transcripts this one is probably the most interesting - demonstrates me getting it to iterate on code, then throwing in some more code I've written and telling it to use additional libraries that might not be in its training data https://chat.openai.com/share/5218799e-0423-49ad-88ba-c72ee27e3fe3
