How Discovery Works
Nine tools, one job each. Run one or all, in any order.
Pick a Tool
Start where you're stuck. No idea yet? Start with the Idea Generator.
Answer a Short Form
A few picks or short answers, often with one sentence about your idea.
Get Pushed Back
Each result names your weakest spot and a fix. "Everyone is my customer" gets caught, not rubber-stamped.
Test It on Strangers
A result is a paper check, not proof. Download it, then test the riskiest part with real people.
