Survey Logic Proofer
Visual logic tester for survey authors in Formbricks, Typeform, and Google Forms that simulates every branching path with synthetic answers and flags contradictions like silent tautologies before respondents see a broken survey.
Product managers and UX researchers designing multi-branch customer and employee surveys
- Branch-tree visualization that highlights unreachable questions, dead-end paths, and orphaned conditions
- Synthetic-respondent simulation that traces every condition against thousands of test answers
- One-click audit report flagging conditions that are always true or always false on the same input shape
- Pre-publish drop-off estimator that predicts respondent attrition at each branch
The Formbricks bug reveals that a single tautological condition silently misroutes every respondent — product teams act on skewed CX data without knowing it, and there is no tool that catches this without reading JavaScript

Customer and employee surveys remain core to product research; silent-logic bugs recur with every new survey
Logic simulation engine is buildable; the harder lift is per-platform import/export formats
