Trails — your structured learning paths
A trail is a sequence of short modules (reading, quiz, exercise) on a topic you pick. You set the audience, the duration (1H Free, up to 1 month on Pro), and the goal; the AI builds the path. Every module unlocks the next when you complete it.
This is the core of Yoonle. Most other surfaces orbit around the trails you finish (XP, streak, achievements, public-profile featured slots).
Quizzes — quick recall checks
Standalone quizzes (separate from the quiz modules inside a trail) live at `/quizzes`. They’re short — 5 questions on Free, 5 to 20 on Pro — and they’re great for "did that revision actually stick?" sessions or for a daily warmup.
Maps — playlists for your learning
A Map is an ordered playlist of references to existing trails and quizzes — the third primitive next to Trails and Quizzes. Use them to plan a personal roadmap, share a curated set with your followers, or follow other Explorers’ picks. Free gets 3 Maps (1 public); Pro unlocks unlimited Maps with custom cover, theme, and PDF/Markdown export. See the "Maps" guide for the deep-dive.
Duels — head-to-head quiz battles
Three modes — Quick Match (random opponent at your level, with optional category filters), Challenge a Friend (someone you follow or any public profile), and Practice (solo run against a bot, no rank impact). All three are available on Free and Pro; the only difference is the cap on duels you can start per day. Free starts 1 per day; Pro starts 10. Sending and accepting challenges are always free.
Duels earn XP and feed your global ranking on `/community`.
AI Tutor — context-aware help
The tutor is an in-context chat that lives inside trails (next to a reading module) and inside quizzes (during an attempt). It can clarify a concept, explain why a quiz option is wrong, or rephrase something — without spoiling the answer outright.
Free gets 10 turns per day; Pro gets 30. Per session is capped at 10 turns; start a new chat for a clean slate. The daily budget is shared across all trails and quizzes.
Community Hub — leaderboards, profiles, follows
Open `/community` to see the global leaderboard (a podium for the top 3 plus your own rank), browse other Explorers’ public profiles, and find people to follow. Every active learner is automatically ranked — there’s no opt-in.
Your public profile
Everyone gets a public profile at `yoonle.com/u/<your-username>` with display name, avatar, XP, level, and Founding Explorer #. Pro can customise it with a cover image (or gradient preset), a bio, and up to 6 featured trails.
