Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

Often I find it really hard to quickly parse other people’s code so I thought maybe ChatGPT could help. ChatGPT does a really nice job of giving clear explanations when you paste in code and ask it to explain it. But the interface is a bit of a pain to use if you’re using it many times a day. It’s also hard to share explanations with co-workers. So I built whatdoesthiscodedo.com. Just paste your code and get your ChatGPT explanation and…

I've used blender for more than a decade and now ask myself what the best way to teach it would look like. Video generally seems the best format to explain how to solve a specific problem, but its not exactly great for larger collections of small bits of information – like blender shortcuts. This is why I made this video/text hybrid website from scratch. If you're a blender user or have experience in teaching others, I'd be very happy to hear your thoughts on it. I'm also posting this here because I assume many of your are professional web developers. I'm a learning hobbyist and…
