I know a product like this will get banned on HN, but I think the technical part is interesting, so I’m taking my shot here.
problem: You try to get ChatGPT to write your landing page copy or email and it comes back... cringe. It's generic. It's as if every output is written by the same person. You try adjusting the prompt and running it through the AI again, and it's just a different version of the same boring output.
There's no real creative exploration going on here. It's one model, one shot, one voice.
solution: Rather than relying on a single AI to compose your content, I created a system with over 100 different AI personas, each with their own area of expertise, personality, and aesthetic (based on real-world data), to rate and score your content in a variety of ways. And then, took some inspiration from AlphaEvolve (Google DeepMind's evolutionary coding agent) [1], we take these personas as a fitness function and apply an evolutionary algorithm to your content in a variety of ways. It’s a search problem, not a one-shot problem.
The result: Copy that's been stress-tested by a diverse panel and evolved through selection pressure. Not just whatever one model generated on the first try.
Would love to hear your feedback.
