Could you build this?

Partial The survey UI and LLM persona prompting are easy to vibe-code, but the calibration score depends on back-testing against real survey data and sound methodology, which a solo builder would not have.

What it would actually take: Build a web app that prompts an LLM with census-based persona profiles (age, region, income, etc.) and aggregates the answers into distributions with segment breakdowns. The hard part is the calibration: you need a library of real survey results with known outcomes, a validated back-testing method, and some statistical or survey-methodology expertise to interpret and publish the accuracy scores honestly.
