Submagic is an AI short-form video editor focused on animated captions, auto-generated B-roll and auto-editing, built for creators who want TikTok/Reels/Shorts-style captions and pacing without manually keyframing every word. It offers a limited free tier (3 videos/month) and paid per-member plans that scale up video volume, length, resolution and frame rate together.
Who builds it
Submagic is a dedicated short-form editing tool rather than a general video generator: you upload a video, and it auto-generates animated captions, suggests or inserts B-roll, and applies auto-editing, aimed squarely at the fast-turnaround short-form content workflow rather than long-form production.
Core features
- Auto captions AI that generates animated, styled captions automatically rather than requiring manual timing.
- Plan-based video volume and length caps that scale together: Free allows 3 videos/month up to 1m30s, Starter 15 videos/month up to 2 minutes, Pro 40 videos/month up to 5 minutes, and Business + API 100 videos/month up to 30 minutes.
- Resolution and frame rate that scale by plan too: Starter exports at 1080p/30fps, Pro adds 2K/30fps, and Business + API adds 4K/60fps — the Free plan's export resolution isn't specified.
- Watermarking on the Free plan, explicitly named 'Submagic watermark', removed ('No Watermark') starting on Starter.
- Video Editing API, included with a metered monthly minute allowance on Starter and Pro (10 min/month) and a larger allowance on Business + API (100 min/month), with additional API credit packs available from $0.10–$0.15/minute.
Pricing
Submagic is freemium with per-member paid tiers:
- Free ($0/month): 3 videos/month, up to 1m30s each, with a 'Submagic watermark'.
- Starter ($19/member/month): 15 videos/month, up to 2 minutes each, 1080p/30fps, no watermark, plus 10 minutes/month of API access.
- Pro: 40 videos/month, up to 5 minutes each, 1080p and 2K at 30fps.
- Business + API: 100 videos/month, up to 30 minutes each, 1080p and 4K at 60fps, with a 100-minute/month API allowance; further API usage can be purchased in packs from $0.10–$0.15/minute.
Because volume, length, resolution and API minutes all scale together per plan, the right tier depends on both how many short videos you produce monthly and how long or high-resolution each one needs to be.
Who it's for
Submagic fits creators and small teams publishing frequent short-form video who want captions, B-roll and pacing handled automatically rather than edited by hand clip by clip. The Free plan is enough to test caption quality on a handful of short videos per month, though output carries a watermark and tops out at 1m30s; Starter removes the watermark and extends length to 2 minutes for a modest per-member fee. Teams pushing higher volume, longer edits (up to 30 minutes), or heavier programmatic use via the API should look at Pro and Business + API, and budget for extra API minute packs if the included allowance isn't enough.
