The tutor for what you're missing.
Skatebored finds the best explanation for exactly where you're stuck.
A tutor that finds
what you're missing.
Find the gap
A few quick questions find the exact concept you're missing, not just the topic you typed.
Find the best explanation
Lectures, open courses, worked examples. Skatebored finds the passage that explains it best.
Learn it in one lesson
The best passages are joined into one lesson, with credit to every source.
Prove it stuck
A fresh question with new numbers shows whether it really clicked.


Real explanations, not ours.
We don't make the videos. We find the best ones that already exist, from teachers who explain it well.
→Every clip credited.
Each passage keeps its source and timestamp, right on screen. The original creator always gets the credit.
→Only what you need.
No hour-long playlists. Just the minutes that teach the step you're missing, or a longer lesson when you need it.
→Stop searching. Start
learning the one thing you're missing.
The Skatebored way of learning
Search gives everyone the same answer. Skatebored starts from yours.
Diagnose
Two students can type "vectors explained" and need completely different help. One can read coordinates but trips on negative components. The other needs magnitude. Skatebored starts by finding which one you are.
- A short diagnostic tests the concept and its prerequisites.
- Your profile separates what you've shown, what needs work, and what has no evidence yet.
- One right answer is never treated as mastery.
Curate
Great explanations are scattered across lectures, courses and channels. Skatebored reads their transcripts, finds where each useful explanation starts and ends, and joins them into one continuous lesson.
- Each passage is picked for what it teaches and what it assumes you know.
- Short bridges smooth over different notation and examples.
- Source and timestamp stay attached to every clip.
Check
Watching isn't learning. After every lesson comes a fresh question with new numbers. Struggle, and Skatebored tries a different explanation or rewinds to a prerequisite. Later, it checks again to see what stuck.
- Answers you got with help are kept separate from ones you got alone.
- A different explanation, not the same video again.
- Retention checks days later, because understanding should last.
Everything you need, in one place.
Your lesson, your progress, your sources.
