ShortMatic Ai is an AI Shorts generation tool for long-video creators, whose main function is to quickly turn existing long videos into vertical short videos suitable for YouTube Shorts, TikTok, and Instagram Reels. It runs in the browser, and the core workflow is: upload or import a long video, have the AI identify highlights worth publishing, add subtitles and crop to vertical, and finally export files for publishing.
Main Capabilities
- AI moment discovery: The AI reads through the entire video, scoring it across transcript text, scenes, and hooks to provide candidate Shorts clips, rather than randomly cutting 15 seconds.
- Automatic subtitles: Supports subtitle styles that follow the speech, from Bold Reels to One Word and other word-level timing styles, and you can also choose not to add subtitles (None) to keep the picture clean.
- Adaptive vertical cropping: Supports 9:16, 4:5, and 1:1 ratios, and subject-aware cropping can keep faces and action within the frame, making the vertical file look like it was shot specifically for mobile.
- All-in-one workflow: Complete the process from long video to publishable Shorts in the same Studio, with no professional editing training required.
How to Use
- Add a long video: Paste a YouTube link or upload a file, supporting types such as podcasts, tutorials, interviews, and webinars.
- AI finds Shorts: ShortMatic picks strong moments, crops to vertical, and prepares subtitles, all in one flow.
- Download and publish: Get files suitable for YouTube Shorts, TikTok, and Instagram Reels, then publish.
Use Cases
- YouTubers: Turn long uploads into daily Shorts.
- Podcasters: Cut a single episode into shareable clips.
- Educators: Repurpose courses into vertical tip shorts.
- Agencies: Deliver client Shorts without full re-editing.
Plans and Limits
- Free plan: 15-minute source video, 5 Shorts, 2 Best Edits, 500 MB storage, 40 background AI tasks per month, no credit card required.
- Paid plans: Creator $7.99, Pro $19, and Agency $49, offering 30-day access through Lemon Squeezy, and unless explicitly stated, it will not auto-renew.
- The tool does not replace human judgment: users still need to reject incomplete clips, correct names in subtitles, and only publish video material they have the rights to reuse.
- The official recommendation is to avoid publishing large amounts of near-duplicate content on the same trending topic.
- Background music is optional, but speech clarity is required.
- If you need an MP4 of your own YouTube upload, you can use YouTube Link To Video, then continue to Long Video to Shorts under the same account.
