Connect ideas through challenges, concept cards, and interactive diagrams, then explore subjects in more depth.

Start learning

Begin at the center of the map. Passing a level opens the next branches. Lessons work offline, and you can pause a challenge and pick it up later.

Choose a language

Newer versions offer English and Simplified Chinese in Settings > Language. Both languages share the same learning progress.

Accounts and progress

You can learn without signing up. When you create an account or first sign in, progress on this device that does not belong to another account is added automatically. Sign in to the same account on your other devices to keep learning. Signing out keeps each account’s records separate.

Email verification and passwords

After signing up, check your inbox and spam folder. The sign-in screen lets you verify your email, resend a code, or reset your password. If you have made several requests in a short time, wait before trying again.

When records need a choice

Completed challenges and progress usually merge automatically. If two devices have different unfinished challenges or chat drafts, choose which record to continue. Local backups of both records are saved first.

AI access

AI is available only to accounts with access enabled. Access and any daily allowance are shared across devices. You decide whether to share question context before using AI. Lessons and progress sync remain available without AI.

Backups and account deletion

Settings lets you or import a progress backup and delete your account. Backups can contain names and conversations; keep them safe. Export any records you want to keep before deleting an account.

About the courses

University tracks are introductions, not complete degree programs. Medical topics are for education and do not replace professional care. AI can make mistakes; check the course references.

Report a problem

Include your device, operating system, app version, what you tried, and what happened. Please do not send passwords, verification codes, sign-in tokens, or sensitive personal information.
