Most brainstorming gets stuck in one of two places: not enough ideas, or too many ideas with no structure. ChatGPT helps by doing three things well:

Provide a small set of constraints to make ideas more realistic. Share who the audience is, what the timeline looks like, how much capacity you have, which channels are available, and how success will be measured. Even a short sentence like, “This needs to work for a team of three within four weeks,” dramatically improves feasibility.

You can also include prior context: what you’ve tried, what worked or failed, and any non-negotiables. This helps ChatGPT avoid repetition and build on existing thinking.

A simple pattern that works well is to intentionally separate idea generation from evaluation.
