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

Hey HN! We’ve been experimenting with integrating multimodal models directly into creative workflows, and ended up building an AI-first image editor using OpenAI’s new `gpt-image-1` (from GPT-4o) inside our SDK. Instead of prompting in ChatGPT and pasting outputs into a design tool, this lets you generate, edit, and remix images all in one canvas. This allows for really interesting new workflows, like quickly mixing multiple images, or creating visual prompts by using annotations and reference on the canvas. Some key details: - Built with our plugin system in CE.SDK (CreativeEditor SDK) -…

Hi everyone, I’ve been using ChatGPT to analyze my journal entries and to reflect with. It works great, I really liked it. I’ve managed to gain some good insights about myself and made improvements. However, there are a few problems: - ChatGPT only remembers key facts about you, it has limited memories - ChatGPT couldn't recall the content of conversations you had with it - For individual ChatGPT products, your private conversations might be used to train future models (see: https://help.openai.com/en/articles/5722486-how-your-data-is...) So, I decided to build my…
