Run your idea past 561 simulated people from a real city. Each one knows what happened on the news yesterday.
Test the instrument. Four personas, no live news. Fine for hello-world.
The instrument with the moat turned on. Sixteen people, each reading today's news in their language.
Every other persona tool runs 2024 brain on your 2026 problem. Same Margaret, same Tokyo, frozen at training cutoff.
Terrasimula pipes today's news into each persona's media diet. CBC for Margaret. Sing Tao for Wendy. Etemad for Reza. Forty-seven sources every morning at 06:00 Pacific.
What you get back is not a hallucination. It is sixteen people reacting to this week.
"What do you think of a $25/month grocery delivery app that brings you essentials in 30 minutes?"
"$25 a month for groceries I could carry myself? In my generation we walked to Save-On. The rain stopped this week anyway."
"At $25 I'd try it once. Two roommates, late dev hours, kale wilting in the fridge. If they hit 30 minutes on Sundays I'm in."
"In Tokyo, konbini was 3 minutes away, 24/7. Here I miss that. $25/month for 30-min delivery would be the closest thing."
"With Ada at six months and 12-hour shifts at Surrey Memorial, $25 is nothing. The 30-minute window is what makes me click. Nothing else delivers that here."
