How to Brainstorm Ideas with OpenAI on Mac
Use Echoo with OpenAI to generate diverse, creative ideas from any Mac app. Select your brief, press a shortcut, and get a structured brainstorm without opening ChatGPT.
Why This Combination Works
GPT-4o's broad training data gives it an exceptionally wide creative palette to draw from. When brainstorming, this breadth translates into more diverse and unexpected ideas — it can connect concepts across industries, disciplines, and domains that you might not consider. It also follows structured brainstorming formats reliably, producing organized output you can immediately act on.
Recommended Model
GPT-4o — its wide-ranging knowledge base produces the most diverse brainstorming output, connecting ideas across domains for unexpected creative combinations.
Example Prompt
