What are the key differences between version 2 and version 3 of the user interface?

A user interface must show what a user is getting before a test starts. The design should let curiosity lead and support closure. Growth metrics are more useful than streaks. Breaks should happen at natural points. A user needs to see their progress. Reports should show both successes and challenges. A moment of pause is important in a report. Identity comes from facts, not rankings. User profiles should ask direct questions. Emotional connection should be part of the design.

The rule

A user interface must show what a user is getting before a test starts.

The design should let curiosity lead and support closure. Growth metrics are more useful than streaks. Breaks should happen at natural points. A user needs to see their progress. Reports should show both successes and challenges. A moment of pause is important in a report. Identity comes from facts, not rankings. User profiles should ask direct questions. Emotional connection should be part of the design.

Version 3 adds a preview screen before a test. This lets the learner see and adjust what they will experience. The main question is now "What stuck?" and a supporting phrase is "After Chapter 1." This design lets curiosity guide the user. Growth numbers, like "247 questions answered," are now the default. These numbers never break. Streaks are an optional feature. Breaks in the test now happen at the end of a section. They do not interrupt puzzle chains or dialogues. Each section starts with a banner, for example, "Round 1 of 5 · Warm-up." This makes the learning structure clear. The report has two parts. One part shows "What you saw clearly" for successes. The other part shows "Where the picture blurred" for challenges. A moment of stillness is designed into the report. There is one empty line between the score and the next actions. User identity is shown with facts, like "47 of 50 Hard correct." This replaces rankings like "Top 25%." A profile question asks about the user on their first visit. The system does not guess user information. Emotional connection is part of the design in all parts of the experience.

A student uses an educational app. In version 2, the app started a test immediately. In version 3, the student sees a preview screen first. The student can change settings before starting. This gives the student more control and understanding. The report shows the student's exact score instead of a percentile rank. This helps the student focus on their own progress.

How should a learning application display a user's progress?

A learning application should show a user's progress. This includes a streak of active days.

How can an AI model help a user sort many items into two groups?

An AI model can use a binary toggle grid. This tool shows a user many items.

How should a system display badges that a user has earned?

The system should show a small row of badges in the main screen header. This row appears after the user earns their first badge.

What are the main differences between a desktop and mobile layout for an AI application?

The content area changes size. On desktop, it fills available space and scrolls.
