Everything you need to create shorts with AI

AI Script Generation

The AI shorts maker writes hook-first scripts optimized for short-form video. Enter a topic or paste an idea, and Toonkit generates a complete script with opening hook, body, and call-to-action timed for 15 to 60 seconds. Prompt enhancement refines your descriptions automatically, and you can edit every line before generation begins. Use the AI video maker for longer scripts beyond shorts format.

Vertical Format Optimization

Every video the AI shorts maker produces is natively composed in 9:16 vertical format. Character framing, text placement, and camera movement are all optimized for mobile-first viewing on YouTube Shorts, Instagram Reels, and TikTok. No cropping or letterboxing required because the composition is built for vertical from the start.

Auto-Captions

The AI shorts maker auto-generates timed captions synced to voiceover and dialogue. Captions boost watch time because most shorts viewers watch without sound. Style, position, and timing are editable after generation. Korean and English voiceover and captions are both supported. For full anime production with captions, combine this with the AI anime generator.

How to make shorts with AI

1

Choose a template

Pick how you want to start. 'Start with Story' lets you build from a script or idea. 'Stylization' transforms your existing images or footage into animation. 'Blank template' gives you a completely open canvas to create freely.

2

Write or Describe

Enter a topic, paste a script, or describe your short. The AI shorts maker enhances your prompt and structures it into a hook-first script optimized for 15 to 60 seconds. One sentence is enough to start, and you can edit every detail before generation.

3

Generate

Toonkit produces your short in 9:16 vertical format with visuals, character motion, voiceover, captions, and background music. Each scene renders with consistent characters and styles. Use quick generation to test multiple directions before committing to a final render.

4

Edit

Fine-tune timing, captions, voiceover, and transitions. Use region editing to fix specific areas and layer separation to adjust characters and backgrounds independently. Every element is editable without regenerating the entire short.

5

Export & Post

Download your finished short in HD with Toon XL upscaling. Export is pre-configured for YouTube Shorts, Instagram Reels, and TikTok specs. Watermark-free output on paid plans with commercial rights included. Post directly or schedule across platforms.

What is the optimal length for YouTube Shorts?

YouTube Shorts supports videos up to 60 seconds. For maximum engagement, 30 to 45 seconds tends to perform best because it gives enough time to deliver value while maintaining viewer retention. The AI shorts maker lets you set your target duration before generation and optimizes pacing accordingly. Instagram Reels supports up to 90 seconds, and TikTok up to 10 minutes, but the sweet spot for all three platforms is under 60 seconds.

Character composition, text placement, camera angles, and transitions are all designed for vertical viewing from the start. There is no cropping or post-processing needed. You can also export in 16:9 landscape or 1:1 square formats if needed for other platforms.

Does it support Korean voiceover?

Yes. Toonkit supports Korean and English voiceover with multiple voice options. The AI shorts maker generates natural-sounding narration synced to your video timing. You can preview different voices before exporting and adjust pacing to match your content. For anime-specific voiceover, combine this with the AI anime generator.
