Long to Short

Turn Long Video into Short Video with AI that Watches It All.

A 3-hour recording hides 30 great moments — finding them by hand takes another 3 hours. AI watches the whole thing and hands you the short videos worth posting.

How it works

Hours In, Highlights Out

No scrubbing the timeline, no notes app full of timestamps

Step 1

Submit the long video

Paste a YouTube, Twitch, or Kick link or upload an MP4 — up to 4 hours.

Step 2

AI watches end to end

Cloud processing means even multi-hour files don't touch your machine.

Step 3

Short videos come back

Vertical 1080p clips with animated captions, each scored 0 to 100.

Step 4

Publish on repeat

Batch-schedule the shorts across TikTok, Reels, and YouTube Shorts.

Why it's different

Why Shorten with AI

4 hours is fair game

Most tools choke on long files. Autoclipper takes up to 4 hours per video, processed in the cloud.

Your time stays yours

The AI does the watching, selecting, cutting, and captioning — you only review and post.

Ranked, not random

The 0–100 virality score orders the output so the strongest short goes up first.

Long-form keeps paying

Every long video becomes a recurring source of short-form content instead of a one-time upload.

Features
