Vidulk is an AI clipping app for iOS, Android and the web that turns long videos and audio into viral short-form clips. It also includes an AI image studio, a professional caption editor and Story tools for chat, post, comment and email videos. One account works on the phone and on the web.

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?

Vidulk is optimized for podcasts, YouTube videos, interviews, lectures, gaming highlights, vlogs, music, sports, and news content. Import from YouTube, TikTok, Instagram, Twitter/X, Facebook, or upload directly from your camera roll.

Does Vidulk work with long videos?

Yes. Vidulk handles videos of any length. Short videos are processed on-device, while longer videos (over 5 minutes) are processed using server-side AI for faster and more reliable results.

What platforms is Vidulk available on?

Vidulk is available on iOS (App Store), Android (Google Play Store) and the web at vidulk.com, all with the same account. The app interface is available in over 30 languages.

We don't sell your data. Videos you upload and stories you save are kept on your account so they show up on your phone and on the web, and you can delete your account and all its data at any time, in the app or on the web. The service providers we use (analytics, AI processing, ad measurement) are listed in our Privacy Policy.

Can I use Vidulk for audio-only content like podcasts?

Yes. Vidulk fully supports audio-only content. Import MP3, M4A, WAV, or other audio files. AI detects the best moments and you can add AI-generated background images or choose from 1,200+ built-in backgrounds to create video clips from audio.

Can Vidulk remove captions or subtitles from videos?

Yes. Vidulk includes AI-powered caption removal that automatically detects and removes burned-in captions and subtitles from your videos before clipping. It works best with dynamic/moving captions like those on TikTok, Reels, and YouTube. Enable it with a simple checkbox when importing your video. Processing takes 7-20 minutes and uses additional credits based on video length.

Can I use Vidulk on the web?

Yes. Sign in at vidulk.com with Apple or Google to import videos, get AI clips, edit captions and make story videos on a computer. It is the same account as the phone app, so projects, clips, stories, Vidulk Unlimited and credits work in both places.

Do I need an account to use Vidulk?

You can write and preview a story on the free tools at vidulk.com without one. Downloading, clipping and saving stories need a free Vidulk account: sign in with Apple or Google.

How do I export clips from Vidulk?

After editing, choose your aspect ratio (9:16, 1:1, 4:5, or 16:9), resolution (720p, 1080p, or 4K), and export. In the app, clips are saved directly to your Photos library; on the web, they download to your computer. Either way they can be shared instantly to any platform.
