Simulating millions of users sounds great until the personas hallucinate behavior.
Turns product testing into a Reddit-like sandbox: spawn opinionated AI personas, run threaded chats and collect 'insights' before you go public. The UI hints at practical workflows (Input / Personas / Chat / Insights and 'real data input now supported'), but the product's usefulness will hinge on persona fidelity, dataset provenance, and how it handles bias and edge cases.
Tackles persona collapse with architecture, but lacks proof-of-concept or working implementation.
Actually tells you why your GPU is slow instead of just showing 100% utilization like nvidia-smi.
Reveals indie launch trends like Vercel hosting 33% of new products.
Langfuse/Helicone angle—LLM-as-judge quality scoring—but no live product or differentiation yet.
