Features
An AI video maker with voiceover, captions and music
One AI video creation tool covers the whole workflow, from analysing your script to the final MP4 with voiceover, captions and music.
AI-Powered Video Generation
Paste a script and get a complete video. Scenes, visuals, narration, captions and music are produced and rendered to MP4 in one pass.
Automated Script Analysis
Your script is split into 3–6 balanced scenes at natural sentence breaks. A word budget keeps narration within the length you pick.
Automatic Scene Visuals
Each scene gets a visual matched to the keywords in its text, brought to life with smooth camera motion and transitions.
Realistic AI Narration Voices
Natural-sounding neural text-to-speech voices, with pacing tuned automatically so the voiceover fits your video.
Automatic Captions and Subtitles
Bold captions that highlight each word as it is spoken, placed in a mobile-safe area. An SRT subtitle file is included.
Background Music Integration
Choose a music mood that suits your story. The music is mixed under the voice so the narration stays clear.
Vertical, Landscape and Square Formats
Export 9:16 for Shorts, Reels and TikTok, 16:9 for YouTube, or 1:1 for social feeds, all at 1080p.

Watch the result right in your browser, then download the MP4 and its captions, or regenerate with one click.

See all 27 questionsWhat is AI Shorts Studio?
AI Shorts Studio is an AI video generator that turns a short script into a finished video. It splits your script into scenes, creates a visual for each one, narrates it with an AI voice, adds word-by-word captions and background music, and renders an MP4 file.
How long can my videos be?
You can choose 5, 10, 15, 20, 25 or 30 seconds. Each length has a word budget, and the generator shows your word count and estimated narration time as you type. If a script is too long it is never cut silently. You get a suggested shorter version that you can accept or edit.
Which video formats are supported?
Vertical 9:16 (1080×1920) for YouTube Shorts, Instagram Reels and TikTok, landscape 16:9 (1920×1080) for YouTube, and square 1:1 (1080×1080) for social feeds. Videos are exported as MP4 files with H.264 video and AAC audio.
How do the AI voiceovers work?
Narration is created with Piper, a neural text-to-speech engine that runs on the server. You choose from the available voices, and the pacing is adjusted automatically to fit your chosen duration. Each voice has its own licence, which is shown when you select it. Check it before using a video commercially.
Are captions added automatically?
Yes. Captions are synced to the narration and highlight each word as it is spoken. You can choose from four caption styles, and an SRT subtitle file can be downloaded alongside the video.
How long does it take to generate a video?
Processing time depends on the video length, the format and how busy the server is. Each step (script analysis, scenes, visuals, voiceover, captions and music, and rendering) is shown live, so you always know how far along your video is.
