About Submagic

If you came here looking for a founder origin story, Submagic's own site won't give you one. The homepage and pricing pages don't say who built it or why. What they do tell is a growth story: a tool pitched as a way to "edit shorts 10x faster with AI" that now claims 4M+ businesses saving "10+ hours every week," plus a featured case study on how Sportskeeda scaled to 2,500+ monthly videos and saw +40% reach growth. So the closest thing to a founding thesis is the product promise itself: "From raw footage to viral shorts in 1 click."

That promise shapes everything on submagic.co. You drop in a podcast, a YouTube link or phone footage, and Submagic adds captions, removes silences, inserts B-roll and pulls out key moments on its own. Captions are the headline feature, with styles in 123 languages and a claimed 99% accuracy. Magic Clips cuts one long video into several shorts. Then a built-in scheduler publishes to TikTok, Reels, Shorts and more, at up to 4K and 60fps. Around that core sits a long list of extras: AI Auto Edit, Auto-Zoom, AI Eye Contact, an AI Video Translator, sound effects, background music, AI avatars for videos you never film, team workspaces, and a newly launched Video Editing API.

Our take: Submagic is built for volume, not craft. If your bottleneck is getting a steady stream of captioned vertical clips out the door, it's aimed squarely at you, and the freemium model with paid plans starting at $15/mo makes it cheap to test. If you want frame-level control over a long-form edit, it isn't that tool, and the marketing numbers (10x, 99%) are claims you'll want to check on your own footage before you commit a content calendar to it.

Key features

AI Captions in 123 languages

Submagic generates styled, animated captions in 123 languages and advertises 99% accuracy, with styles designed to keep viewers watching.

Magic Clips

Magic Clips takes one long video, finds the key moments and cuts them into multiple shorts so you can repurpose a podcast or YouTube upload in one pass.

One-click AI Auto Edit

The auto editor removes silences, inserts B-roll and handles cuts and trims automatically, which is where the "10x faster" claim comes from.

Scheduling and publishing

You pick a date and platforms inside the editor and Submagic publishes on schedule to TikTok, Reels, Shorts and other channels, at up to 4K and 60fps.

AI avatars

AI Actors Studio lets you create shorts with AI avatars instead of filming yourself or hiring talent.

Team workspace and API

Teams can review, edit and publish in a shared workspace with brand consistency, and the new Video Editing API lets you automate the whole pipeline programmatically.

Best for

podcasters repurposing long episodes into shorts
agencies and media teams publishing dozens of clips a week
solo creators who hate captioning by hand
multilingual brands posting in several languages
developers automating video output via API

Skip if

Skip it if you need detailed, timeline-level control for long-form edits, since the whole product is built around short vertical clips
Skip it if your brand depends on fully human, on-camera content, because features like AI avatars and AI Eye Contact push in the opposite direction
Skip it if you need to vet the team behind a tool before buying, since the site shares no founder or company background

Pros & cons

Pros

Captions in 123 languages is a wide range for a tool at a $15/mo starting price
Covers the full chain from upload to scheduled publishing, so you don't need a separate scheduler
Accepts raw files, phone footage or just a YouTube link, which cuts out a download step
Real-scale proof point: Sportskeeda reportedly pushes 2,500+ videos a month through it
The Video Editing API makes it usable as infrastructure, not just an app

Cons

Headline numbers like "10x faster" and "99% accuracy" are vendor claims with no methodology on the site
The source pages we reviewed don't spell out per-plan limits such as monthly video counts or export caps, so you'll learn those inside the app
Feature sprawl is real: 20+ listed features from AI Eye Contact to sound effects, which can make it hard to tell what's core and what's filler
Focused on short-form, so it won't replace a proper editor for long YouTube videos

Frequently asked questions

How much does Submagic cost?

Submagic is freemium, with a free option to try it and paid plans starting at $15/mo. That puts its entry price in the same range as Opus Clip and well below hiring a freelance editor.

How many languages do Submagic captions support?

Submagic advertises caption generation in 123 languages with 99% accuracy. That's broader language coverage than most short-form caption tools offer.

Can Submagic turn a long video into multiple shorts?

Yes, Magic Clips extracts key moments from a long video and cuts them into several shorts. It works from uploads or a YouTube link, similar to how Opus Clip handles repurposing.

Which platforms can Submagic publish to?

It schedules and publishes directly to TikTok, Instagram Reels, YouTube Shorts and other channels. Exports go up to 4K at 60fps.

Is Submagic better than CapCut?

Submagic is faster for hands-off captioning, clipping and scheduled publishing, while CapCut gives you more manual creative control. If you're publishing at Sportskeeda-style volume (2,500+ videos a month), Submagic's automation is the stronger fit.

How Submagic compares
