Endless cartoons and autoplay
One video ends, the next one starts. Kids keep watching, and nobody chose what they watch.
For parents and teachers
Turn the living-room TV into your child's classroom.
Make lessons on your phone from photos, PDFs and videos. Add your own voice. Play them on the big screen and run the class from your phone.
Works with Android TV and Google TV
Sound familiar?
Screen time doesn't have to be wasted time.
Teaching at home feels hard
You want to teach, but small screens, cables and slide files get in the way.
Class and home don't connect
Teachers send worksheets home. Parents don't know how to turn them into a lesson.
How it works
Three steps to your first lesson
Make a lesson on your phone
Pick photos, a PDF or a video. Record your voice for each page, or let the app read it aloud.
Pair the TV once
Open TellyClass on the TV and scan its QR code. Next time they find each other automatically.
Tap Play on TV
Turn pages, pause and change the volume from your phone. Your child just watches and learns.
Who it's for
Made for the people who teach kids
Tuesday night, 15 minutes before bed
Mom takes photos of ten animal cards, records "What animal is this?" on each page and plays it on the TV. Her son shouts the answers from the sofa. When the lesson ends, the TV stops. No next video.
- Your own voice on every page
- Pages turn by themselves when the voice ends
- Learn English, Korean, Japanese and more with built-in voices
No laptop, no HDMI cable
Export your slides to PDF, import them once, and teach from anywhere in the room. Your phone is the remote.
- PDFs up to 100 pages, one slide per page
- Change pages while you walk around the class
- Still works over the internet when your phone is on 4G
Coming soon
Today's class becomes tonight's fun at home
Teachers will send a whole lesson, with their own voice, to parents in one link. Parents open it and play it on the TV, no teaching skills needed. Until then, send the PDF over chat and parents can open it in TellyClass.
- The teacher's voice comes along
- One link per lesson
- Parents just tap Play

Safe by design
Less endless cartoons. More time learning with you.
The lesson ends, the TV stops
No autoplay, no "up next", no recommendations.
No ads
Nothing pops up between pages. Nothing on screen tries to sell to your child.
Private lessons
Your lessons are visible only to your family.
Big screen, more distance
Kids watch from the sofa instead of holding a phone close to their face.
The remote
A remote that feels like magic
Your phone runs the class. The TV just shows it.
Instant
On the same Wi-Fi, the TV reacts as you tap.
Even on 4G
Left the Wi-Fi? Control continues over the internet.
Scan once
Pair with a QR code. It reconnects by itself next time.
Ready to replay
The TV keeps a copy of each lesson, so replays start almost instantly.
FAQ
Questions parents and teachers ask
