A hook, three or four beats each with a teaching visual, a quick check and a takeaway.
A VIDMOAT PRODUCT, BUILT ON OUR API
StudyTok: your syllabus as a feed of short study videos
A TikTok-style feed of short narrated lessons that follows what you actually study: your level, country, school, course and exam. Each video is written and produced as you scroll, with a quick check after it so it sticks.
Free to start with a free Vidmoat account. Open source under the MIT licence.
HOW IT WORKS
Your course, one swipe at a time
Tell it what you study
Your level (middle school to postgraduate, professional, or just curious), your country, school, course or subjects, and the exam you are preparing for. StudyTok matches the course to its built-in catalog, or researches what your institution actually teaches.
Swipe through your syllabus
Lessons are written and produced unit by unit, in order, while you scroll. Nothing is pre-recorded, and nothing is exported to a video file: every lesson plays live in the Vidmoat player.
Answer the quick check
After each lesson the video waits for your answer. A right answer brings the unit back for review after 1, 3, 7 and then 21 days; a wrong one brings it back 20 minutes later.
EIGHT FORMATS
A new kind of lesson every swipe
Each lesson runs 25 to 50 seconds in one of eight formats, and each format has its own structure, type, captions, colour grade, transitions, music and narrator. The feed never plays the same format twice in a row.
Myth vs fact
A belief stamped MYTH, the truth stamped FACT, and two reasons why.
5 things
Rapid-fire facts with a numbered counter over full-bleed footage, then a ticked recap.
Exam drill
An exam-style question, a pause to try it, the worked solution, the common mistake and a marks tip.
Story
Chapters with datelines and real photos, letterboxed with a cinematic grade.
Flash drill
Question and answer cards with a beat to answer each before it flips.
Why?
One big why, answered as because, which means, so.
DM thread
A student texts a tutor, and the answer unfolds bubble by bubble.
Sample cards from the StudyTok landing page, one for each format.
WHAT IS INSIDE
Made for revising, not for scrolling past
Follows your course
A built-in catalog for common programs and web research for everything else. A researched course is kept and shared with classmates on the same course.
Narrated and captioned
A different narrator for each format, word-timed captions, sound effects on the cuts and a music bed ducked under the voice.
Real teaching visuals
Diagrams, steps, timelines, comparisons, equations and stats, alongside real photos and stock footage.
Remembers for you
Spaced repetition brings each unit back for review when it is due, and the feed walks you through the course in order.
A feed that learns
A recommendation engine weighs what you like, where you are in the syllabus, what is due for review and what you just saw. A Why sheet shows the parts, and Less turns a topic down.
Tune it
Add your own topics, choose video length, visuals and difficulty, turn narration off, and untick what you have already mastered.
It installs like an app: add it to your home screen and it opens full screen.
BUILT ON THE VIDMOAT API
Every lesson is a real Vidmoat project
StudyTok writes each lesson, turns it into edit commands and sends them to the Vidmoat API with the narration, captions, photos, footage, sound effects and music. It reads back the finished edit and plays it live in Vidmoat's embed player, the same canvas as the editor, so nothing waits on a render. People sign in with Sign in with Vidmoat.

QUESTIONS
About StudyTok
Is StudyTok free?
Free to start. You sign in with a free Vidmoat account, and your first videos are made on StudyTok's own credits. After that you connect your own Vidmoat account, and each new video you set off spends your Vidmoat credits. Videos that are already made keep playing either way.
What does StudyTok see of my Vidmoat account?
Signing in asks only for the read-only account scope: StudyTok reads your name and email once and discards the tokens. Only when you choose to use your own account for new videos does it ask for the generation scopes, and those tokens are sealed at rest. It never touches your renders or exports.
Which courses does it cover?
Common programs are in a built-in catalog. For any other course, StudyTok researches what your institution teaches and builds the syllabus from that, and you can add topics of your own in your own words.
Are the lessons real video files?
No. Each lesson is made as a Vidmoat project and played live in Vidmoat's embed player, so nothing is ever exported to MP4.
Can I install it?
Yes. StudyTok is a web app you can install: on Android or a computer use Install StudyTok in your profile, and on an iPhone use Share, then Add to Home Screen. It opens full screen.
Can I run my own copy?
Yes. StudyTok is open source under the MIT licence. Its README explains how to run it with a Vidmoat API key (and an Anthropic API key for writing lessons and researching courses) and how to deploy it.
