How XP is earned
XP is awarded only on quiz and exercise modules. Reading modules give you 0 XP, on purpose (so a long reading-only trail can’t farm points).
The XP value of each module is decided by an AI evaluator at trail-creation time, based on four factors:
- Subject complexity (cooking basics 1.0× → quantum physics 3.0×).
- Module type (quiz 20–60 XP, exercise 30–150 XP).
- Module length (longer = proportionally more).
- Trail difficulty (Beginner 1.0× → Advanced 1.6×).
Levels
Your XP total maps to a level: Explorer (level 1), Pathfinder, Trailblazer, and so on. Levels are purely cosmetic right now — a tag on your profile and avatar menu — but they give you a sense of momentum.
Streaks — the gentle nudge
A streak counts how many consecutive days you’ve completed at least one module, quiz, or duel. The current count appears in your avatar menu and on your dashboard.
Miss a day and the streak resets to 0. The cost of a slip is small — just start again. Streaks are a gentle nudge, not a punishment.
Streak freeze (Pro)
Pro subscribers earn streak-freeze charges that can rescue a streak after a single missed day. Pro accounts gain 1 charge every 7 active days and can hold up to 2 at once, so a regular learner always has a safety net ready.
Freezes are NOT automatic. The day after you miss, an "at-risk" banner appears on your dashboard with a "Use a freeze" button — one tap consumes one charge and your streak picks up where it left off. If you miss a second day before clicking, the streak resets and the freeze opportunity is gone (the banner says "too late" and disappears).
Designed for the bad week (illness, travel, deadline) without making the streak meaningless. Free accounts see the feature as a Pro perk in the streak chip; charges are Pro-only.
Achievements — the side trophies
On top of XP, you collect achievements as you reach milestones: first trail finished, first 7-day streak, first perfect quiz, first podium finish, and so on. They live on your profile and badge into the dashboard for a few days after you unlock them.
Achievements don’t change what you can do in the product — they’re a recognition layer. Some are visible on your public profile, some stay private to you.
What counts as "completed"
A module is completed when you tap "Mark complete" (reading) or submit an answer (quiz / exercise). A trail is completed when every module is.
Completed trails stay accessible forever in your dashboard, regardless of plan. If you downgrade from Pro to Free, you keep read access to everything you’ve already finished.
No retakes, on purpose
In V1 you can’t retake a quiz or exercise to improve your score. We made this choice deliberately to make the score meaningful — if everyone could retake, the score would just be "did you eventually figure it out". Retake support is on the roadmap for V1.5.
