How Shorts Maker helps creators publish faster
The AI Shorts Maker streamlines short-form content creation by automatically identifying the most engaging segments of any long-form video. It eliminates hours of tedious scrubbing and manual clipping, leveraging intelligent algorithms to isolate high-retention moments. With built-in kinetic captions and precise speaker tracking, it ensures your shorts are perfectly optimized for modern algorithms while maintaining complete data privacy via client-side processing.
Start by importing your source footage, whether it is an MP4 file or a public link. The AI will instantly analyze the audio and visual cues to surface the best moments. Once the segments are identified, you can adjust the start and end points, tweak the dynamic subtitles, and finalize the vertical formatting. The robust WebAssembly engine then renders the final clips directly in your browser, ready for immediate distribution across TikTok, Instagram, and YouTube.
Best practices
- Always review the AI-selected clips to ensure context is maintained before exporting.
- Use high-contrast colors for your animated captions to maximize mobile readability.
- Combine multiple short moments into a fast-paced compilation for higher retention.
- Consistently monitor which clip formats perform best on specific social platforms.
Common mistakes to avoid
- Uploading videos with extremely low audio quality, which hinders accurate moment detection.
- Ignoring the 9:16 crop framing and accidentally cutting off the main speaker.
- Exporting clips without adding visual hooks or engaging caption styles.
- Attempting to process 4K hour-long videos on low-RAM mobile devices.
How to use Shorts Maker

Publish across platforms
Distribute the generated vertical clips to YouTube Shorts, TikTok, and Instagram Reels.
Creator tips
- Verify that the first 3 seconds contain a strong visual pattern interrupt and caption hook.
- Use the video compressor tool to shrink files before upload if you are on a restricted mobile network.
- A/B test three different dynamic hook variants to see which segment captures the platform algorithm fastest.
While other tools charge $20+/mo and require slow cloud uploads, Seloice is free, secure, and processes everything on-device.
Troubleshooting
AI analysis fails to start
Ensure you have a stable network to fetch initial WASM modules and that your browser supports WebAssembly.
Crop frame cuts off speaker
Use the manual slider in the preview workspace to adjust and lock the 9:16 bounding box on active participants.
Export times are slow
Close other browser tabs to free up system memory (RAM). Browser-based editing is CPU-heavy.
Frequently asked questions
How does the AI determine viral potential?
Our localized AI processes the video audio stream to index speech pacing, structural audience triggers, volume shifts, and keyword clusters, calculating a real-time virality probability score.
