About "AI Shorts"

How to Use

Upload your materials

Upload the PDFs, PowerPoint files, or images you want to turn into a video using the browser-based dashboard. No dedicated software installation is required.
AI auto-generates the script

The AI analyzes the content of your uploaded materials and automatically drafts narration text for each slide.
Review and edit the script

Review the generated script and make any necessary edits. Adjusting the wording and length will result in more natural-sounding narration.
Choose a language, voice, and speaker, then generate

Select from 15+ languages including Japanese, specify a speaker (male, female, etc.), and generate the audio. You can also configure subtitles, captions, and effects.
Share or download

Distribute the finished video via a share link, or download it as a file to use for in-house training, product explanations, and more. Viewership analytics are also available.
