01 · Overview
What is Polyfactual?
Polyfactual is a Chrome extension that adds provider-generated market analysis, confidence scores, risk assessments and research history inside Polymarket pages. Its floating panel reads visible market context and calls encrypted analysis APIs without connecting a trading wallet or executing orders. The workflow is a research layer, not a verified forecast: AI outputs can be wrong, and extension permissions, privacy disclosures, model behavior and performance claims require continued review.
