Developer & Creator of ContradictMe
Last updated:
Liz Stein is a developer focused on building AI systems that promote critical thinking and intellectual honesty. As the creator of ContradictMe, they designed a platform that challenges users' beliefs with research-backed counterarguments rather than confirming existing biases.
The motivation behind ContradictMe stems from a recognition that most AI systems optimize for user engagement and agreement, which can reinforce echo chambers. By contrast, ContradictMe deliberately presents the strongest opposing evidence, encouraging users to test their assumptions and think more rigorously about complex topics.
Liz Stein's approach emphasizes transparency in AI systems—every argument includes quality scores, source credibility ratings, documented limitations, and peer-reviewed citations. This commitment to evidence-based reasoning helps users distinguish between well-supported claims and speculative arguments.
An AI system that challenges beliefs with research-backed counterarguments. Built with Next.js, Algolia Agent Studio, and a curated database of peer-reviewed arguments. Winner of the Algolia Agent Studio Challenge (2026).
