What are AI short video tools?
AI short video tools automate the creation of vertical content for YouTube Shorts, TikTok, and Instagram Reels. They fall into two main categories:
- Clip extractors – repurpose long videos (podcasts, interviews) by finding the best moments and adding captions.
- Commentary generators – create original scripts, voiceovers, and subtitles for silent or b‑roll footage.
Whether you run a faceless channel, a sports highlights page, or a product review account, these tools save hours of manual editing. Here are the 10 best, ranked by real‑world testing.
1. OpusClip – Best overall clip extractor
Best for: Podcasters, interviewers, long‑form repurposing.
Price: $19/month (free plan with watermarks).
OpusClip automatically finds viral moments from videos up to several hours long. It provides a virality score (e.g., 98/100), dynamic captions, auto‑framing, and auto B‑roll. Processing takes ~20 minutes, depending on server load.
Pros: High-quality clips, keyword‑based clipping, emoji support, solid free tier.
Cons: No original commentary, can’t handle silent videos, slower during peak hours.
2. 2shorts.ai – Best free option for speed
Best for: Beginners testing the waters.
Price: Free (or $10/month for 5 hours of AI analysis).
2shorts.ai generates clips from pre‑analyzed videos in under a minute. It’s ideal if you just need basic captions and don’t require voiceover.
Pros: Instant processing, completely free tier.
Cons: Basic subtitles (white text on black), no AI voice or commentary, limited editing.
3. Vizard – Fast processing with multi‑speaker framing
Best for: Interviews and multi‑speaker videos.
Price: Free with watermark, paid plans from ~$15/month.
Vizard processed a 54‑minute video in just 3 minutes. It handles two speakers well, and its editor allows resizing and layout changes.
Pros: Very fast, versatile editor.
Cons: Free version leaves watermark, no AI commentary.
4. ShortVox – Best for AI commentary & original narration
Best for: Faceless channels, educators, sports content, product demos.
Price: Free plan / Pro $29/month / Business $99/month.
ShortVox writes original scripts and generates voiceovers for silent videos. Powered by Google Gemini 2.5 Flash and OpenAI TTS, it delivers a script, voice, and subtitles in under 3 minutes. You can edit the script before voice generation.
Pros: Unique commentary feature, 10 styles (Funny, Hype, Educational, etc.), 14 subtitle styles, clean 1080p export on Pro.
Cons: Not for long‑form repurposing (max 2.5 min on Pro), free version limited to 1 video/month with watermark.
5. Munch – Includes keyword research (but slow & pricey)
Best for: Marketing teams needing trend analytics.
Price: $49/month (no free plan).
Munch offers a “magic post” feature with titles and captions, plus keyword search volume. However, it took 2 hours to process a 54‑minute video, and clip transitions can be glitchy.
Pros: Built‑in keyword research.
Cons: Very slow, expensive, no free trial, no original commentary.
6. Vidyo.ai – Decent free credits, but awkward cuts
Best for: Budget repurposing.
Price: Free 75 minutes, then $19/month.
Vidyo.ai gave 25 shorts in 18 minutes, but clips often cut off mid‑sentence and auto‑framing is inconsistent.
7. CapCut – Free all‑in‑one editor (not fully automated)
Best for: Manual editing with AI assist.
Price: Free (with optional pro features).
CapCut includes auto‑captions, text‑to‑speech, and basic AI effects. It’s not fully automated like OpusClip or ShortVox, but it’s excellent for creators who want more control.
8. Pictory.ai – Good for summarising long videos
Best for: Summarising webinars and courses.
Price: $19/month.
Pictory extracts highlights and creates short summaries. It works well for educational content but lacks the polished captions of OpusClip.
9. Klap – Fast clip generation for social media
Best for: Quick social media posts.
Price: Free trial, then $29/month.
Klap focuses on speed and simplicity, but it offers fewer customization options.
10. Submagic – Caption‑focused tool
Best for: Adding engaging captions to existing clips.
Price: $14/month.
Submagic specialises in animated subtitles and emojis, but it doesn’t generate clips or commentary.

How to choose the right AI tool for your workflow
Ask yourself these three questions:
- Do you have existing dialogue? → Use a clip extractor (OpusClip, Vizard, 2shorts, Vidyo.ai).
- Is your video silent or b‑roll? → Use a commentary generator (ShortVox).
- What’s your budget? → Free tiers: 2shorts.ai, Vizard (watermark), ShortVox (1 video/month).
For podcast highlights, OpusClip remains the industry standard. For faceless channels, ShortVox is a strong option, but CapCut and Pictory also work well with manual effort.
