Before asking real people, ask 100 AI personas first. AIDEA is a private space to pressure-test your idea before you show it to anyone. You write a single paragraph. 100 AI personas respond in about a minute. You see who pays attention, where they hesitate, and what gets misread β laid out as a distribution, not a single verdict. β What it does You write one paragraph describing your idea. AIDEA simulates 100 personas reading it and responding. The result is eight metrics, a hundred verbatim responses, the riskiest assumptions in your idea, and a concrete validation plan for the human conversations that should come next. β Who it's for Β· Solo founders, designers, and product people testing an early direction Β· Side-project builders who want to sanity-check before investing weeks Β· Anyone preparing user interviews who wants to refine the question first Β· Marketers gauging how a tagline or price might be read β How it works 1. Describe your idea in one paragraph 2. Specify who you'd want to ask 3. Wait about a minute while 100 personas respond 4. Read the eight metrics, the full responses, the risky assumptions, and the validation plan β What AIDEA promises Β· AI is not a substitute for real users. It can be a first mirror. Β· Results come as distributions, not as one-line verdicts. You see the full spectrum. Β· Risky assumptions are surfaced explicitly. The confidence of the analysis is shown alongside what the result cannot decide. β What AIDEA does not promise Β· It does not deliver the final answer on market validation. Real user interviews are still essential. Β· The 100 personas reflect a general population distribution, not domain experts. Β· Results are an input to your decision, not a guarantee of success. β Features Β· 100-persona analysis in approximately one minute Β· Eight metrics covering interest, comprehension, price fit, differentiation, and more Β· Verbatim responses with keyword frequency analysis Β· Automatically surfaced risky assumptions Β· Stage-by-stage validation plan with interview questions Β· Local history of all your validations β A note on use This app uses AI simulation. Results are a reference for your decision-making, not a forecast of real-world reactions, revenue, or user behavior. Read the results critically, and validate the riskiest assumptions through real conversations. Made by: A solo founder who needed a place to test ideas honestly, built for others doing the same.
