In my experience the use of generative AI is a bit of a hit or miss experience. Some time the results are pretty useful, and other times the results are pretty useless. Here a few examples of tools, or how others used AI tools that can be pretty impressive:
ChatGPT for Design Sprints: an experiment by Benjamin Dehant who ran a design sprint with ChatGPT
Holler: a one question survey where you then can use an AI to generate a report based on the answers just by asking questions to the AI
Mixio: An AI that creates a landing page you can use to test your next product or service idea.
