The format that prints views
Looping gameplay + fast voiceover + bold captions is one of the highest-retention short formats on TikTok. This skill makes it a one-message workflow.
Generate brainrot-style shorts from a prompt
The looping-gameplay-plus-voiceover format that dominates TikTok. Tell Claude a topic or script; it generates the voiceover over royalty-free gameplay-style footage with big centered captions — the exact recipe behind the genre.
You type
Make a brainrot short explaining the Roman Empire's collapse in 60 seconds.
…and Claude drives the whole pipeline below on your machine.
Why this beats a blank script box
Royalty-free, no franchise risk
ViralMint ships generic gameplay-style backgrounds — no copyrighted 'Subway Surfers' or 'Minecraft' footage — so your clips won't get pulled. Drop in your own gameplay if you prefer.
Claude writes the punchy script
Brainrot lives or dies on pacing. Claude writes the voiceover in the right rapid cadence — you bring the topic.
How Claude makes a brainrot short
-
Script or topic in
Give Claude a finished script or just a topic — it writes the voiceover copy in the fast, punchy cadence the format demands.
-
Voiceover over looping footage
tool_brainrot_video lays a TTS voiceover over royalty-free, gameplay-style background footage on a loop — or your own clip if you provide one.
-
Bold centered captions + export
Big centered word-by-word captions are burned in (the brainrot caption preset), and the finished vertical mp4 comes back via list_videos.

Frequently asked
What is a 'brainrot' video?
A short-form format where a fast-paced TTS voiceover plays over looping, hypnotic gameplay-style footage with bold centered captions. It's engineered for retention and dominates TikTok and Shorts.
Do you use Subway Surfers or Minecraft footage?
No — ViralMint uses generic, royalty-free gameplay-style backgrounds to avoid copyright takedowns. You can supply your own gameplay clip if you want a specific look.
Can Claude write the script too?
Yes. Give it a topic and it writes the voiceover in the punchy brainrot cadence; or paste your own script and it just renders.
What does it cost?
Prepaid per-render at roughly cost plus a small margin, no subscription. Claude estimates before rendering.
