AI picks the moments, not a stopwatch
The clip picker scores segments for hook strength and standalone payoff from the transcript — so you get the moments that actually carry a short, not every 60-second chunk.
Repurpose any long video into viral clips
Drop a YouTube or podcast link in chat. Claude downloads it, transcribes it locally, runs ViralMint's AI viral-clip picker to find the moments most likely to pop, and exports them as captioned 9:16 clips — ready to post.
You type
Pull the 5 best clips from this podcast: https://youtube.com/watch?v=…
…and Claude drives the whole pipeline below on your machine.
Why this beats a blank script box
Local transcription, no upload
Whisper runs on your machine. Your source video and transcript never leave your computer — only the clip-scoring AI call does.
A podcast becomes a week of content
One hour-long episode yields a handful of export-ready shorts in a single chat message — the highest-leverage repurposing workflow there is.
How Claude turns a long video into clips
-
Download + transcribe locally
download_video pulls the source (1,800+ sites supported) and chains Whisper transcription automatically — all on your machine.
-
Find the viral moments
extract_viral_clips runs ViralMint's AI clip picker over the transcript to surface the 3–5 segments with the strongest hook and standalone payoff — not arbitrary time-slices.
-
Caption and export
Each clip gets word-by-word captions in your chosen style. bulk_export_videos returns them as a tidy set of vertical mp4s, ready for TikTok, Shorts and Reels.

What sources can it download from?
YouTube, podcasts, and 1,800+ sites supported by yt-dlp inside the desktop app. Cookie-gated platforms inherit your browser session locally.
Are the clips watermarked?
No. ViralMint never watermarks output — the exported clips are clean mp4s you fully own.
What does it cost?
