Interactive Video Lessons
Use any YouTube video. No re-recording, no new tools — the video you already teach with becomes the lesson.
Learning that clicks
Turn any video into a lesson that grades itself.
VLK lets teachers drop questions right onto a YouTube video. Students answer as they watch, get instant feedback, and every score lands in your gradebook automatically.

What you get
Everything a video assignment was missing
The video you already teach with, turned into a lesson that checks for understanding and keeps the score.
Real-Time Timestamp Questions
Pin multiple-choice questions to exact moments. The video pauses, the student answers, then it plays on.
Auto-Gradebook
Every answer is scored the moment it is submitted. Open the gradebook and the whole class is already there.
Classes & Assignments
Make a class, share a join code, assign a video with a due date. Students see exactly what is due.
Content Library
Save and organize your videos into folders, reuse them across classes, and build a library over the year.
Works on Any Device
Students join on a Chromebook, tablet, or phone. Nothing to install.
How it works
From a video link to a graded lesson in four steps
-
1
Find a video
Search YouTube right inside VLK, or paste a link to a video you already use.
-
2
Add your questions
Scrub to the moment that matters and drop in a question. Repeat as many times as you like.
-
3
Assign it to your class
Pick a class, set a due date, and share. Students get it instantly.
-
4
Watch the gradebook fill in
As students answer, scores post automatically. No marking pile.
The difference
A plain video link vs a VLK lesson
| Plain video link | VLK lesson | |
|---|---|---|
| Do you know they watched? | ||
| Questions while watching | ||
| Grading | By hand, later | Automatic, instant |
| Feedback to the student | Immediate, per question | |
| Reusable next year | Re-share the link | Duplicate the lesson |
| Fits your existing videos |
When students answer as they watch, the lesson sticks.
VLK turns passive watching into active learning — and gives you the proof it happened.

What teachers say
From classrooms across the country.
“I used to wonder if my kids actually watched the videos I assigned. Now I know — and they are thinking about them, not just playing them in the background.”
Ms. Alvarez
7th Grade Science
“The auto-gradebook alone saves me an hour every week. That is an hour back with my students.”
David Okafor
High School Biology
“Setup took five minutes and my class was using it the same day. The kids picked it up faster than I did.”
Karen Mitchell
5th Grade
