AI user-simulation tools emerge to test product decisions in hours, not weeks

Lenny Rachitsky highlights a growing trend: teams using AI "simulations" to quickly test product ideas and flow tweaks instead of waiting weeks for A/B tests.
He lists tools like simileai, primitivelabsai, SyntheticUsers and Tenera. Tenera, for example, trains LLM personas per user segment, simulates real user behavior (not stated preferences) against product variants before any code is written, claims to compress validation from 2-4 weeks (A/B testing) to under 2 hours, and charges $49/month.
