Did you find any way to generate good ideas with AI? Anecdotally, I found it incredibly unsatisfactory in this sense. It normally re-hashes old ideas without any internal coherence, like those novelty websites combining two existing startups to create a random mission (e.g. “AirBnB for motorbikes”).
When you consider that LLMs are trained on what can be scrapped from the web, the so called "creativity" comes from mashing together less commonly co-associated ideas.
