I have a custom tool I use to help out posts like this together: https://tools.simonwillison.net/annotated-presentations

I updated the design with Claude 3.7 Sonnet (thinking) last night, notes on that here: https://simonwillison.net/2025/May/15/annotated-presentation...

This is awesome. Thanks for taking the time to create this type of in-depth content and share so generously!

Still making demos huh? Have you ever observed anyone else using your techniques and the kinds of problems that they may be having?

Yes, it feels like half the internet is talking about using LLMs to write code now and the expected and unexpected problems they run into. This was a good recent piece: https://albertofortin.com/writing/coding-with-ai

No have you personally worked with anyone else or a large group or maintaining these things?

What kind of things do you mean? Software written with the help of LLMs to write the code, or systems that call out to LLMs as part of how they work?
