How does AI clip detection work?

Import a video or paste a link — Vidulk transcribes the audio using AI speech recognition that supports 99 languages, then analyzes the transcript to find the most engaging moments. Each clip is scored by virality potential and categorized as Insight, Story, Funny, Tactical, Controversial, or Emotional.

What languages does Vidulk support?

Vidulk supports speech recognition in 99 languages including English, Spanish, French, German, Korean, Japanese, Chinese, Arabic, Hindi, Portuguese, and many more. The app interface is available in over 30 languages. Language is detected automatically.

What caption and editing features are available?

Vidulk includes 7 caption styles (Highlight, Karaoke, Typewriter, Minimal, Bold Pop, Gradient, and more), customizable fonts, colors, and animations. Export in multiple aspect ratios (9:16 for Shorts/Reels, 1:1 Square, 4:5 Portrait, 16:9 Landscape) at up to 4K resolution.

What is the AI Image Studio?

AI Studio lets you generate thumbnails and images from text prompts with 6 artistic styles including Realistic, Illustrated, Abstract, Minimalist, Anime, and Watercolor. It also includes an Image Enhancer that upscales images 2x or 4x. All processing happens on-device for privacy.

What content types does Vidulk work with?
