Loving this product. Easy to and intuitive to figure out and start using. It doesn't seem to have any limitation on the number of sub-tasks you can add. I don't use the AI functionality much but did test it out - if you are working on something and not sure how to get started on, it does a great job of giving you a list of tasks to achieve what you're trying to do. It'll come in handy when I start focusing on my marketing tasks. Overall a good product so far and I'm not had a need to reach out to the support team as everything works as it was advertised.
