Background

Study brainrot made with Cliptalk, and the notes behind each one

Each is a finished render from a few lines of typed notes. A PDF does the same job with your own material. Copy the notes to see how it was asked for.

Study recap: photosynthesis for the exam

“Study recap over Subway Surfers gameplay: photosynthesis explained for an exam. Light hits the chlorophyll, water splits, carbon dioxide comes in through the stomata, and the plant builds glucose and lets oxygen out. Cover the light-dependent and light-independent stages in one line each and end on why it matters for every breath you take. Keep it accurate and simple. Warm conversational female narrator (Zara), highlight-style word-by-word captions, focused study music.”

Study recap: how vaccines work

“Study recap brainrot over a satisfying hydraulic press loop: how vaccines actually work, explained for an exam. The immune system meets a harmless version of the threat, makes antibodies and memory cells, and the next time the real thing shows up it is recognised instantly. Cover why boosters exist and why herd immunity protects people who cannot be vaccinated. Keep it accurate and simple. Steady British broadcaster voice (Daniel), comic word-by-word captions, focused study music.”

Remix

Study recap: the water cycle for the exam

“Study recap over Temple Run gameplay: the water cycle explained for an exam. Evaporation from oceans and lakes, condensation into clouds, precipitation as rain or snow, and collection back into rivers and groundwater. One clear line per stage, then why the same water has been going around since the dinosaurs. Keep it accurate and simple. Warm conversational female narrator (Zara), highlight-style word-by-word captions, focused study music.”

Remix

Why Rome actually fell (study brainrot)

“Study brainrot: why the Roman Empire actually fell. Rome fell to payroll, not barbarians — coin debasement, three percent silver by the year 270, soldiers demanding raises until collapse. Fast reveals, accurate facts, epic music, big captions.”

How to turn a PDF into a brainrot video

1. Upload the PDF

Drop in slides, class notes, a chapter or a paper. It's read in your browser in a few seconds, and a long PDF lets you pick the pages for one chapter.

2. Say what to focus on, or don't

Leave it blank for the key ideas, or ask for an exam cram, a quiz, or the hard part explained like you're 12. Read the script before you render and fix any line.

3. Pick the gameplay and render

Choose Subway Surfers, Minecraft parkour, Temple Run or satisfying footage and a voice. You get a captioned 9:16 short with music, ready for TikTok and Shorts.

What PDF to brainrot actually is

PDF to brainrot took off in 2024 as a study hack: feed in a reading you can't face, get back a short where an AI voice talks you through it over Subway Surfers or Minecraft parkour gameplay. The gameplay keeps your eyes busy while the voice and the captions carry the material, which is why a chapter you skimmed twice suddenly sticks. Most tools read the text out or summarise it flat. Cliptalk writes it like a real brainrot short instead: a hook that makes you stay, three to six ideas explained properly, a quick fact every line or two, and a last line that tests you. Want it from typed notes instead of a file? The text to brainrot generator takes pasted text.

What works, and what doesn't

Any text PDF up to 50MB

Slides, notes, chapters, papers, study guides. The file is opened on your device and never uploaded; only its text goes to the script writer.

About 20 pages per video

One short is written from about 10,000 words. A longer PDF gets a page picker, so make one video per chapter instead of one blurry one.

No scans or passwords

A scanned PDF is pictures with no text to read, so run OCR first. Password-protected files need a copy saved without the password.

What people turn into brainrot

The PDFs students and creators bring, and the way to ask for each one.

Lecture slides into an exam cram

Upload the week's slides and ask for an exam cram: the definitions, numbers and facts most likely to come up, each said once over Subway Surfers.

A textbook chapter into a recap

Pick the chapter's pages and leave the prompt blank: you get the ideas that matter most, in the order that makes them easy to follow.

A study guide into a quiz

Ask it to quiz you: a question, a beat to guess, then the answer, hardest one last. Rewatch it on the bus the morning of the test.

A research paper, explained simply

Turn a dense paper into the one finding that matters and why, with every number kept exactly as the paper states it.

Reading in another language

Upload an English chapter and pick Spanish, or the other way round: the ideas are translated and the facts stay put.

Course notes for your audience

Teachers and study creators turn handouts into a run of shorts, one per topic, for a class group chat or a study channel.

Frequently Asked Questions

Upload the PDF in the generator at the top of this page, optionally say what to focus on (a chapter, "quiz me", "explain it like I'm 12"), and press Generate Script. Cliptalk reads the PDF, picks the ideas that matter most and writes a fast brainrot script you can read and edit. Then pick the gameplay loop and voice and render it into a captioned 9:16 video.

Reading your PDF and writing the script is free with no signup, so you can see exactly what the video will say first. Rendering the video takes a free account, which comes with 50 free credits and no card. A 45 to 60-second short costs roughly 11 to 20 credits (the voiceover is billed at 0.1 credit per word, and the gameplay loop is free), so the free credits make two or three videos. After that, plans are $19, $39, or $59 a month.

The file itself never leaves your device. The PDF is opened right in your browser, and only the text inside it is sent to the AI that writes your script. Nothing is stored until you sign in and render, and then what's saved to your account is the finished video and its script, not your PDF.

Four things stop a PDF: it's a scan (pictures of pages with no selectable text, so run it through OCR or export it with text first), it's password-protected (save a copy without the password), it's over 50MB (upload just the chapter you need), or it isn't really a PDF. If the PDF opens but the video feels thin, it's usually too long: pick the pages for one chapter and make a video per chapter.

Any length up to 50MB. One video is written from about 10,000 words, roughly 20 dense pages or 60 slides. A longer PDF shows a page range picker so you choose the chapter, then you make another video for the next part. That's on purpose: a 45-second short teaches four ideas well, not a whole textbook badly.

The script is written only from your document: every fact, number, name and definition comes from the PDF, and the writer is told never to add claims it doesn't make. You also see the full script before anything is rendered, so you can fix a line or cut one in seconds. Check it the way you would check your own notes.

Yes. The loop can be Subway Surfers, Minecraft parkour, Temple Run or oddly satisfying footage, and you pick from 140+ voices across 30+ languages. The script is written in the language you choose, even when the PDF is in another one, so an English chapter can become a Spanish study video.

Yes. Every video comes out as a 9:16 vertical with the voiceover, word-by-word captions and music already in place, sized for TikTok, YouTube Shorts and Reels. Download it and post it, or open it in the Cliptalk editor first to fix a caption.

Turn your next PDF into a brainrot video

Upload it above and read the script free, then render the captioned short over Subway Surfers or Minecraft parkour, ready for TikTok, Shorts and Reels.
