Studying

The topic you're stuck on, explained at your level — the night before the exam if need be.

Teaching

A lesson for the topic you never have time to build — with a quiz and flashcards to hand out.

Just curious

The things nobody sat you down and explained. Interest rates. Immune systems. Tides.

What you get

Not a clip. A whole lesson.

Every video arrives with the things a good course has, generated for that lesson alone.

The loop

Share a lesson and it pays you back.

Making a lesson costs a credit for every minute it runs. Share it, and each time another user unlocks it, 10% of its length is credited back to you.

After ten unlocks the lesson has paid for itself, and everything beyond that is profit. Pro plan users get 20% back instead of 10%. Earned credits never expire.

See everything a lesson comes with
How accurate is it?+

Each lesson is written from the sources it lists, and the sources are shown with it. Treat it like careful notes from a diligent student — check anything you'll rely on.

How long does it take?+

Minutes, not days. You can close the tab and come back — the lesson keeps being made.

Can I set the level?+

In the question itself: “for a nine-year-old”, “I know the basics, go deeper”. Vocabulary, pace and examples all follow.

What does it cost?+

Your first five-minute lesson is free, no card needed. After that, plans are a monthly allowance of credits; a credit makes one minute of video.

Why Xplainly

The best explanation is the one made for your question.

Libraries of videos answer the average question. You never asked the average question. Xplainly builds the lesson after you ask, with your framing, your level and the example you care about.
