colino
Your textbook as video lessons
Free
lino makes video lessons for your math homework. It explains the theory, guides you through the exercises and checks your work.
colino makes a video lesson out of your math textbook. You snap the page, lino explains it out loud, and lino checks your work.
Your lesson starts with your own book. Snap the pages your class is on. lino reads them and makes your lesson in about a minute, and you can see lino work on your page while you wait. Then the lesson plays.
lino explains the theory out loud while the steps appear on the screen, with the examples and exercises from your page. Then you do the exercises from your book, one by one.
Stuck and not sure what to ask? Just tap "I don't get it," and lino explains that step. You can also type or say your own question.
When you're done, snap your notebook. lino checks your work and marks it on your own photo, so you see what went well and where to look again.
Algebra, geometry, precalculus: if it is in your textbook, colino makes it a lesson.
For parents: colino works with the math textbook your child already uses, so the help follows the class.
