Best AI Tools for YouTube Shorts in 2025
YouTube Shorts reward consistency, and consistency is hard when every 45-second video still needs a hook, a script, an edit, captions and a cover frame. The good news is that AI tools now handle most of the repetitive work, so you can spend your time on ideas instead of timelines. Below are the tools worth knowing, grouped by the part of the workflow they speed up.

Scripts and ideas
1. ChatGPT or Claude
ChatGPT and Claude are general-purpose AI assistants, and for Shorts they are most useful at the very start of the process. Ask for 20 hook variations for one topic, turn a blog post into a 40-second script, or tighten a rambling draft so it lands in under a minute. Both can also suggest titles, on-screen text and a call to action.
A practical tip: give the assistant your target length (for example, "about 110 spoken words"), your audience and your tone, and ask it to mark where visual cuts should happen. You will get something much closer to camera-ready than a generic "write a YouTube script" prompt.
- Best for: Creators who struggle with hooks or need to batch a week of scripts in one sitting.
- Watch out for: Facts and statistics. Always check anything the AI states as true before you say it on camera.
- Pricing: Both have free plans; paid tiers start from about $20/month (check current pricing).

Editing and captions
2. CapCut
CapCut is one of the most popular editors for vertical video, available on mobile, desktop and the web. It offers templates, auto-captions, background removal, effects and a large library of fonts and transitions. Many creators edit an entire Short on their phone in CapCut without ever opening a laptop.
- Best for: Creators who want a fast, all-in-one editor and are comfortable with a template-driven style.
- Pricing: Free plan available; Pro is about $20/month and unlocks premium templates and AI credits (check current pricing, as features and tiers change often).
3. Descript
Descript lets you edit video by editing its transcript. Delete a sentence in the text and it disappears from the video. It can remove filler words like "um" and "uh," clean up audio, add captions and resize footage for vertical formats. This is especially handy if your Shorts are talking-head videos or podcast clips.
- Best for: Talking-head creators, podcasters and anyone who finds timeline editing slow.
- Pricing: Free plan available (limited media minutes, watermarked exports); paid plans from about $16/month billed annually (check current pricing).
4. Submagic
Submagic focuses on one thing: eye-catching captions. It generates animated subtitles with emoji, highlighted keywords and styles that mimic the look of popular short-form creators. It also offers extras such as auto-zooms, B-roll and sound effects to keep viewers watching.
- Best for: Creators who rely on bold on-screen captions to hold attention, especially for viewers watching with sound off.
- Pricing: Paid plans with a free trial; entry plans have been listed from roughly $12–$19/month depending on billing (check current pricing).
Repurposing long videos into Shorts
5. OpusClip
OpusClip takes a long video, such as a podcast, webinar or YouTube upload, and automatically finds the most engaging moments. It reframes them to vertical, adds captions and suggests which clips are most likely to perform. If you already make long-form content, this can turn one upload into a week of Shorts.
- Best for: Podcasters, coaches, educators and anyone sitting on a back catalog of long videos.
- Watch out for: AI clip selection is a starting point. Review each clip to make sure it makes sense without the surrounding context.
- Pricing: Free plan available (limited processing minutes, watermarked); paid plans from about $15/month (check current pricing).
Voiceover
6. ElevenLabs
ElevenLabs generates natural-sounding voiceovers from text in many languages and voices. It is popular with faceless channels, explainer Shorts and creators who want to dub their content into other languages. Paid plans add voice cloning, so you can create a digital version of your own voice for quick fixes and narration.
- Best for: Faceless channels, multilingual creators and anyone who does not enjoy recording narration.
- Watch out for: The free plan is for non-commercial use and requires attribution, so upgrade before using it on a monetized channel. Only clone voices you have the right to use.
- Pricing: Free plan available; paid plans from about $5–$6/month (check current pricing).

Visuals, covers and B-roll
7. Canva
Canva is a design platform with AI features (grouped under Magic Studio) for generating images, removing backgrounds, resizing designs and writing text. For Shorts creators it is useful for cover frames, branded text overlays, channel banners and quick vertical video edits using its templates.
- Best for: Creators who want a consistent visual brand without hiring a designer.
- Pricing: Free plan available; Canva Pro unlocks the full AI toolset and premium assets, from about $15/month (check current pricing).
8. Runway
Runway is an AI video platform that can generate short video clips from text or images and offers editing tools such as background removal and motion effects. For Shorts, it is most useful for creating B-roll, transitions or stylized visuals that would be expensive or impossible to film.
- Best for: Creators who want cinematic or experimental visuals, and faceless channels that need fresh footage.
- Watch out for: Generation uses credits, which can run out quickly. Plan your shots before you start generating.
- Pricing: Free starter credits; paid plans from about $12/month billed annually (check current pricing).

A simple Shorts workflow using these tools
You do not need every tool on this list. Here is one lean workflow that covers the whole process:
- Brainstorm hooks and write a script in ChatGPT or Claude.
- Record yourself, or generate a voiceover in ElevenLabs.
- Edit in CapCut or Descript, trimming pauses and adding auto-captions.
- Add B-roll from your own footage or Runway, and polish captions in Submagic if you want a bolder style.
- Create a branded cover frame in Canva.
- Feed your long videos into OpusClip each week to fill gaps in your schedule.
Start with one tool that removes your biggest bottleneck. If editing takes the longest, fix that first. If you never know what to post, start with scripts.
How to choose
- On a tight budget: CapCut, Canva and a free AI assistant cover scripting, editing and visuals at no cost.
- Already making long videos: OpusClip or Descript will give you the biggest time savings.
- Running a faceless channel: Pair ElevenLabs for voice with Runway or stock footage for visuals.
- Captions are your style: Submagic or CapCut's auto-captions will handle most of the work.
Whatever you choose, keep your own voice in the script, check auto-captions for misheard names, and read each tool's commercial-use terms before publishing on a monetized channel.
Final thoughts
AI will not come up with a great idea for you, but it can remove most of the busywork between that idea and a published Short. Pick one or two tools that fix your slowest step, build a repeatable routine, and add more only when you hit a new bottleneck. Prices and features change often, so check each tool's site before you commit to a paid plan.
