About TestSynthia

TestSynthia lets founders, product managers and marketers test ideas without recruiting people. The user describes an idea, pricing or message, chooses an audience from a panel of more than a million AI personas grounded in what people say and do, and runs a simulation that returns directional answers in about ten minutes. Use cases include finding a price early buyers accept, validating an idea before building and testing positioning and messaging.

Each simulation ends in a full report. Responses are coded into segments ranked by intent with sentiment splits and a readiness tier, broken down by age, gender, occupation and combined segments, and every theme traces to verbatim persona quotes. Reports also cover jobs and friction, verification and next steps, and export as a shareable PDF. Responses are coded from several perspectives and scored for agreement between raters. A simulation starts at $2.99, and an ICP generator, audience panels and case studies are linked.
