What you prefer
Completions, replays, saves and the formats you choose tell us what you find accessible and interesting. We use them to shape presentation, not to claim you've mastered anything.
Learn
Follow your interests, your way.
"Help me understand this."
Learn turns a passing interest into a real understanding. Journeys are built from what you're curious about and how you're progressing, with enough structure to make it stick and none of the homework feel.

How it adapts
A learning profile built gradually.
No long survey at sign-up. SmartScroller starts with ordinary discovery and gets better over time, using the signals you choose to share.
Observe
Topics, saves, replays and skips, with your consent.
Ask, occasionally
A quick question about pace, voice or animation now and then.
Check understanding
Short knowledge checks and recall, not just watch time.
Adapt
The sequence, presentation and pace of what comes next.
Two kinds of evidence, used honestly.
What you understand
Knowledge checks, exercises and delayed recall show what has actually stuck. That's the only evidence we use to talk about your progress.
We won't tell you that you have a permanent learning "type". We adapt to what works for you right now, and keep checking.
