This is emblematic of how quickly AI development is progressing. This was probably a killer idea when they started. Now it's just a slow interface to generate brief phrases on a topic. It doesn't make the slides. You have to copy-paste the generated text into your tool of choice. One. Slide. At. A. Time. And you have limited ability to provide feedback or regenerate to improve the output. ChatGPT can produce structured results from more complex prompts.
I hope their v2.0 is significantly improved.
