I’ve been working on a lot of marketing campaigns lately and noticed one recurring problem — most messages sound good in theory, but you never really know which one connects with which audience until you’ve already spent weeks testing.

So, I built the Brand Messaging Test AI Agent. It helps marketers instantly discover which messages resonate best with different customer personas. Instead of guessing or A/B testing manually, the agent analyzes your copy and gives you clear insights into what works, what doesn’t, and why.

It’s designed for startups, agencies, and anyone trying to improve their brand communication without wasting hours or ad budget.

Would love feedback from the HN community — what would you like this tool to test or analyze next?
