AlphaCut
The AI Shorts editor that turns any long video into viral Shorts in 3 minutes
AlphaCut turns any long video into ready-to-publish Shorts in 3 minutes. Paste a YouTube URL and the AI picks the viral-worthy moments, writes broadcast-quality captions, and generates hooks and viral titles trained on the engagement patterns that actually move retention. The proprietary STT model handles slang, proper nouns, and natural cadence without the manual cleanup pass that generic captioning tools force on you. For solo creators, agencies, and producers alike, AlphaCut saves hours of editing every week. Keep your existing Shorts style with a powerful templating system, and lean on AI speaker tracking, background music and noise removal, silence trimming, AI hooks, and TTS narration to compress editing time. Native YouTube, TikTok, and Instagram integrations publish Shorts directly to each platform, and scheduled uploads keep the entire content pipeline organized.
Submagic
Global Shorts caption automation tool supporting 50+ languages
Submagic is a shorts captioning tool whose biggest strengths are stylish caption templates and word-by-word highlight effects. It supports auto-captioning in 50+ languages, and runs auto-reframing, AI B-roll insertion, and AI highlight detection (splitting a long video into multiple shorts) directly in the browser. The free plan is limited to 3 videos per month, 90 seconds max, with watermarks, and the advanced AI features sit behind plan-specific 'AI Credits' caps — so heavy users hit limits even on Pro tiers.

Real User Reviews
AlphaCut completely changed my workflow. I drop in a YouTube link and walk away — three minutes later I have shorts that actually convert. The caption accuracy is on another level compared to anything else I've tried.
I used to dread editing shorts after every long-form upload. With AlphaCut the AI picks the highlights I would've picked myself and the captions need almost zero correction. My retention numbers jumped within two weeks.
I tested every major shorts tool before settling on AlphaCut. Nothing else gets the highlight detection and caption quality right at the same time. The templating system is the cherry on top — my shorts finally look consistent.

Auto-captioning is accurate, the workflow is fast, and the finished shorts look polished and on-trend.
Submagic isn't worth it unless you commit to the higher tiers — too many features sit behind the paywall.
The app is unstable, video and audio drift out of sync mid-edit, and support takes days to reply. Hard to recommend in production.
