Best AI tools for YouTube Shorts in 2026: make, clip and caption

How are YouTube Shorts different from TikTok?

Shorts look like TikToks, but they live inside YouTube, which changes what works. Viewers often arrive from a channel they already watch, so Shorts that connect to your longer videos do well. Search matters more: titles and the first line of the description help Shorts get found long after posting. And many successful Shorts are clipped from long-form videos rather than made from scratch.

• Vertical 9:16, up to a few minutes, though 15 to 45 seconds is the sweet spot for most.
• A hook in the first second, like on any short-form platform.
• A searchable title with the topic in plain words.
• A loop or a clear payoff, since rewatches count.

Disclosure: we make Dromana, one of the tools below. We've noted which jobs other tools do better.

It also helps to think about Shorts as a funnel rather than a separate channel. A Short reaches people who have never heard of you; the goal is to make them curious enough to tap through to your channel or a longer video. That's why the best Shorts often feel like a teaser: one surprising moment, one strong visual or one useful tip, with a clear reason to see more. AI tools help you produce those moments faster, but the idea still has to come from you.

Which AI tools are best for YouTube Shorts?

• Dromana: new vertical clips from one photo, like trend looks, product shots or cinematic scenes.
• Opus Clip: finds the best moments in a long video and cuts them into captioned Shorts.
• Descript: edit by editing the transcript, then export vertical Shorts.
• Kapwing: browser editing with auto-subtitles and resizing for Shorts.
• Captions: AI edits and subtitles for talking-head Shorts.
• InVideo: faceless explainer Shorts from a script, with stock footage and voiceover.
• Canva: thumbnails, title cards and branded intros.

Which tool is best for making Shorts from scratch?

If you don't have footage, generate it. Dromana turns a photo into a 5 to 10-second vertical clip, either from a ready-made look such as bullet time, the time-travel vlog or lost in a book, or from your own description in AI Video. Several clips cut together with a voiceover make a full Short. New accounts start with 70 free credits, no card; a look video uses 70.

Which tool is best for turning long videos into Shorts?

If you already make long YouTube videos, clipping is the highest-leverage use of AI. Opus Clip and similar tools scan a long video, pick moments with a clear hook, reframe them vertically around the speaker and add captions. Review every clip; the AI picks good moments often, not always. Descript is the better choice when you want to choose the moments yourself by reading the transcript.

How do I make a faceless YouTube Short with AI?

1. Step 1

   Write a 30-second script

   One idea, a hook line, three points and a payoff.

2. Step 2

   Generate the visuals

   Script-to-video tools like InVideo assemble stock footage; for custom scenes, generate clips in Dromana from photos or descriptions.

3. Step 3

   Add a voiceover and captions

   Record your own voice or use a text-to-speech tool, then add subtitles in Kapwing or Descript.

4. Step 4

   Title it for search

   Put the topic in plain words in the title.
