aivideoYouTube Shorts are vertical, usually under 60 seconds, and — because most people scroll with sound off — captions are close to mandatory. The right AI tool handles all three for you: vertical framing, fast editing and automatic subtitles.
We compared our 12-tool database against those requirements. These are the picks that actually fit Shorts.
Best overall: Veed
Veed is the strongest all-rounder for Shorts. It runs entirely in the browser, has best-in-class auto subtitles, and supports dubbing into 50+ languages. That matters if you want to republish one Short across markets.
- From $19/mo (Creator plan), with a free tier
- 4K export, watermark-free on paid plans
- Score: 8.0/10 — “best-in-class auto-subtitles”
The trade-off: the free tier is 720p and watermarked, and AI credits reset annually.
Best faceless option: Fliki
If you’d rather not be on camera, Fliki turns a script into a Short with realistic text-to-speech and stock footage. It’s built for exactly this use case (its use cases include “faceless YouTube”).
- From $28/mo, free tier available
- 80+ languages and voice cloning
- Score: 7.9/10 — “great TTS voices”, “blog-to-video”
Fliki has no AI avatars, so it’s voice + footage rather than a talking head.
Best budget: InVideo
InVideo is the cheapest way to get polished Shorts at scale, with 5,000+ templates and 50 languages.
- From $9/mo — the lowest paid entry in our database
- Score: 8.0/10 — “5000+ templates”, “easy for beginners”
No AI avatars, and the free tier is watermarked.
Best for repurposing: Pictory
If you already have longer videos or blog posts, Pictory clips them into Shorts automatically and adds captions.
- From $29/mo, no free tier (14-day trial instead)
- Score: 7.7/10 — “long-form to clips”, “auto captions”
Also consider: Kapwing
Kapwing is a close Veed alternative with strong AI subtitles and dubbing in 40+ languages.
- From $24/mo
- Score: 8.4/10
The verdict
- Editing + captions first: Veed
- No camera needed: Fliki
- Tightest budget: InVideo
- Repurposing existing content: Pictory
Every tool above has a free tier (except Pictory’s 14-day trial), so you can test the caption quality before paying. Captions are the single biggest conversion factor for Shorts — prioritize that.
