Riddle - The Ultimate Quiz Maker & Engagement Platform

# Riddle > Riddle is a SaaS platform for creating interactive content — quizzes, surveys, personality tests, polls, prediction games, forms, minigames, leaderboards, flashcards, and stories. Content is built in a no-code visual editor (with AI assistance) and embedded via iframe or JS snippet into any website, CMS, or app. Riddle is not a CMS, website builder, or email tool — it creates interactive content that plugs into your existing stack (CMS, CRM, DMP, analytics, ad servers). 100% GDPR-compliant, ISO 27001 certified, WCAG 2.1 accessible. Used by BBC, Red Bull, Tate Modern, Amazon/Goodreads, Stage Entertainment.
