The right explanation for
exactly where you're stuck

Skatebored checks what you already know, finds the clearest passages from videos and courses across the web, and stitches them into a lesson built around your gap.

Meet Ollie, your curriculum builder

A tutor that finds,
not one that lectures

Ollie doesn't make its own videos. It searches the explanations that already exist, picks the passage that matches your gap, and joins them with short bridges so the lesson flows from one source to the next.

Let's check negative numbers before vectors.

Start where you
actually are

A few focused questions test the concept you asked about and the prerequisites behind it. If you can read coordinates but not add negative components, that's where the lesson starts.

Explanations from
everywhere, credited

Different resources explain the same idea in different ways. Skatebored picks the passage that fits your gap, supplies missing context, and always shows where it came from.

A curriculum that
rebuilds itself

Every answer updates your concept map. Get it right on a fresh question and you move on. Struggle, and Skatebored routes you back through the prerequisite or tries a different explanation.

Know what actually
stuck

One right answer isn't mastery. Skatebored separates what you've shown, what needs attention, and where there isn't enough evidence yet, then checks again later to see if it lasted.

From algebra to college calculus

Every subject is broken into small knowledge components, so Skatebored can find the exact one you're missing. Pick a subject and play with it.

Covered concepts

Grounded in how
people actually learn

One-to-one tutoring has long outperformed classroom teaching (Bloom's “2 sigma problem”). Skatebored brings part of that to everyone, tracing understanding concept by concept, the way a good tutor does.

Built for the time
between lessons

For students working through homework or exam prep, and for tutors and teachers who want practice to continue between sessions, with results that show what to cover next.

What a session looks like

Example sessions, showing how Skatebored responds to different gaps.

Try it: find your gap

Search a topic, answer one question, and watch Skatebored choose the explanation, then check whether it worked.
