Save your spot, on every device.

The DCM website is 100% free for everyone. Accounts are optional but give you more features. Sign in however you like — we can email you a link, or you can use a password.

What you get

  • Set it up once. Line the site up to your textbook or your teacher's class, and that arrangement is waiting on your account every time you come back. No hunting for it again, and it opens at the last video you watched, on any device.
  • Save videos for exam review. Star one as you watch and it lands in a single list on your account, on every device.
  • Make playlists for exams. Group videos into your own collections like "Exam 1" or "Final review", and share the link with a study partner.
  • Be first in line. New features go out to account holders before anyone else.
  • Teaching? Set up a class page, free. Pick the book or course your class follows so the order matches theirs, trim it to only what you're covering, or group it by week, unit or exam. Then share one link. Your students never pay and never need an account of their own.
  • Who doesn't love an encouraging or funny stick figure? Sign up and you'll see more. The more you visit, the more you can decide how much you see them.
  • Free forever, not free for now. No trial, no card, nothing to upgrade to later. This is one teacher trying to help anyone with math, and everything above is yours for nothing.

Anyone who signs up now becomes a legacy member, permanently. The status never expires, and it comes with special privileges as the site grows.
