Daily Knowledge

What

A daily trivia quiz service where users answer 5 questions, collect stamps, and convert them to Toss points. Designed with large text and intuitive UI for users in their 50s–60s. Vertex AI automatically generates fresh questions daily, with 3 easy and 2 medium questions to maintain a sense of achievement. A 3-layer reward system — daily completion, attendance streaks, and weekly missions — drives consistent re-engagement. Knowledge level (cumulative correct answers) and knowledge age (7-session moving average) provide learning progress feedback. Available as a Toss mini-app.
