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 — laid out as a distribution, not a single verdict. — 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. — Who it's for · Solo founders, designers, and product people testing an early direction · Side-project builders who want to sanity-check before investing weeks · Anyone preparing user interviews who wants to refine the question first · Marketers gauging how a tagline or price might be read — 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 — What AIDEA promises · AI is not a substitute for real users. It can be a first mirror. · Results come as distributions, not as one-line verdicts. You see the full spectrum. · Risky assumptions are surfaced explicitly. The confidence of the analysis is shown alongside what the result cannot decide. — What AIDEA does not promise · It does not deliver the final answer on market validation. Real user interviews are still essential. · The 100 personas reflect a general population distribution, not domain experts. · Results are an input to your decision, not a guarantee of success. — Features · 100-persona analysis in approximately one minute · Eight metrics covering interest, comprehension, price fit, differentiation, and more · Verbatim responses with keyword frequency analysis · Automatically surfaced risky assumptions · Stage-by-stage validation plan with interview questions · Local history of all your validations — 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.
