Turn every interaction into insight. Daily Challenges are questions, quizzes, and polls that customers actually want to answer — because every response earns points and XP.
Give customers a reason to show up every day
Daily Challenges are the core engagement loop in Nudj. Each challenge is a question, quiz, poll, or trivia prompt that customers complete to earn points and XP. They take seconds to finish — and every answer captures zero-party data that tells you what your customers actually want.
This is the mechanic that drove 99% completion rates across supermarket campaigns in Canada and Austria, and generated 300K+ behavioural signals per campaign for a Romanian retailer.
Why challenges beat discount codes
Discount codes train customers to wait. Challenges train customers to show up.
Zero-party data capture — every answer reveals preferences, purchase intent, and motivation
AI-generated content — describe what you want to learn in plain English and the Agentic OS builds the challenge automatically
Mid-flight tuning — the AI monitors participation and auto-adjusts difficulty to maintain a 99% completion rate
Multiple formats — multiple choice, polls, votes, image uploads, open text, and more
Configurable rewards — set points, XP, or badge rewards per challenge. Tie them to giveaway entries for maximum engagement
How it works
Create — build a challenge in the admin panel or let the AI generate it from a prompt
Configure — set rewards, scheduling, and targeting
Launch — customers see it in the widget and complete it in seconds
Learn — data flows to your analytics dashboard and Shopify customer segments automatically
Before & After
Before challenges: You send a survey email. 3% open rate. You learn nothing about the 97% who ignored it.
After challenges: Customers answer because they earn rewards. Completion rates hit 99%. Every response enriches their profile.
The Duolingo connection
Duolingo doesn't make you study — it makes you want to study. Daily Challenges use the same behavioural science: small tasks, immediate rewards, visible progress, streak pressure.
