We built a real quiz in Riddle and scored it on the same five things we test every tool on – pricing, ease of use, customization, privacy, and support – then compared it with Typeform, Involve.me, Outgrow, and Interact. Here is what we found.

What is Riddle?

Riddle is a comprehensive interactive-content platform that goes well beyond a simple quiz maker. It is designed to help businesses, publishers, and agencies generate leads, gather audience insights, and boost on-site engagement. Rather than focusing on a single content type, Riddle offers 35+ interactive formats – quizzes, personality tests, polls, surveys, lead forms, predictors, leaderboards, and interactive stories – all built on a no-code editor. Its standout traits are truly unlimited usage and a privacy-first architecture that appeals to enterprise and EU customers.

Key features

35+ content types: Quizzes, personality tests, polls, surveys, forms, predictors, leaderboards, and story/game formats.
Unlimited everything: All paid plans include unlimited quizzes, views, responses, and leads – no overage fees when content goes viral.
Privacy-first: Data hosted in the EU (Germany and Luxembourg), ISO 27001 certified, GDPR-compliant, with no third-party tracking by default.
Lead generation: Embeddable lead forms with native Salesforce, Mailchimp, Brevo, and ActiveCampaign integrations, plus Zapier and webhooks.
AI and customization: AI quiz generation from a topic or URL, full white-labeling, custom fonts, and custom CSS on higher plans.

Ease of use and interface

Riddle’s drag-and-drop builder requires zero coding: pick a content type, add questions and media, and customize the design. The editor is clean, there is a large template library and an AI generator to get started fast, and a real-time preview shows how content looks on any device. Combined with famously quick support, it is a genuine pleasure to use for beginners and professionals alike.

Pricing and plans

Riddle keeps pricing simple: every paid plan includes unlimited content, views, responses, and leads (plans differ in concurrent users, domains and seats: 10,000, 20,000 or 50,000 concurrent users, 3, 10 or 15 domains, and 1 or 5 seats; checked October 5, 2026 on Riddle’s pricing page). Prices are shown here in USD, and Riddle uses the same number across currencies (129 EUR = 129 USD = 129 GBP). There is no permanent free plan, but a 14-day, full-featured free trial with no credit card required.

Pro: $129/month ($119/month billed annually) – white-labeled branding, your own logo, unlimited responses and leads.
Business: $399/month ($349/month billed annually) – adds custom CSS and fonts, mp4 upload, advanced tracking, and in-content ads.
Enterprise: $799/month ($749/month billed annually) – SSO, custom DPA and infosec, dedicated account manager, custom user roles, and 5 seats included.
AI creation: The built-in AI generator creates quizzes, polls and personality quizzes from a topic or URL, up to 150 (Pro), 250 (Business) or 550 (Enterprise) AI-generated pieces of content, shown as credits on the pricing page. Creating with AI through the Riddle MCP connector is unlimited, according to Riddle.

AI assistant and MCP access

Riddle has an official MCP server that connects AI assistants such as Claude, Claude Code, Cursor and VS Code to the Riddle Creator. It covers all 9 Riddle types and, in Riddle’s words, nearly every block, form field, setting and logic option: an assistant can create and edit Riddles, apply templates and styling, publish or take them offline, and pull stats such as views, starts, submissions and answer breakdowns. Everything it builds appears in the normal Creator and stays fully editable by hand, and edits to a live Riddle land in its draft first. The MCP is included in every plan, free trial included (only the validation tool needs Business or Enterprise), and AI creation through the MCP is unlimited, according to Riddle. Riddle’s September 17 release notes add ChatGPT to the supported assistants (release log). Checked October 20, 2026 (source).

API access

Riddle has a documented REST API (v3, API key). The Builder API creates and edits quizzes, polls, personality tests, forms, predictors, minigames and stories; the Manage API lists, publishes, embeds, tags and deletes Riddles and returns lead data; a Stats API reports per Riddle, project or account; a generative AI API creates Riddles from a topic or a URL; and a Question Banks API manages reusable question pools. The Builder API, Stats API and leads endpoint need a Business or Enterprise plan, and Riddle does not list a separate API fee. Checked October 6, 2026 (API docs). Compare all 29 tools in our API overview and MCP overview.

Final verdict

If you are serious about interactive content for business growth, Riddle is the tool we’d pay for. Unlimited usage, privacy-first EU infrastructure, an intuitive editor, and fast support make it an easy recommendation for brands, publishers, and agencies. It is not the cheapest option, and casual one-off users won’t need this much power – but for professional, high-volume use the value is hard to beat. Riddle earns a near-perfect 4.9/5.
