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.

We don't sell your data.

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

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.

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.

What each app is for

Captions, from Mirage, is an AI video editor for people who film themselves. Its paid plans add AI Edit styles, AI avatars and digital twins, a chat-based editor, AI translation and lip dub, and generated B-roll, music and images. It also has Clips, which turns long videos into ranked short clips. Its help docs place Clips on the web, with files up to 3 hours and 10GB or a YouTube or public link.

Vidulk focuses on clipping and short-form editing: AI-found moments, 65 caption styles, auto-reframe on faces, four aspect ratios, a hook title card, progress bar, logo, music with ducking and 4K export, on phone and web.

Pricing

Captions Max is $24.99 a month and Frontier is $69.99 a month, with higher Frontier tiers at $139.99 and $279.99. Captions notes that these are iOS plan prices. Plans run on AI credits, and unused credits roll over up to three times your monthly allowance. A free version includes basic tools such as trimming and transitions.

Vidulk Unlimited is $9.99 a week, $19.99 a month or $179 a year on the web, with no clipping cap. Credits are $7 for one video or $19 for ten.

Android and where Captions is stronger

On Android, Captions offers Captions Lite, which its help center describes as essential manual video editing, with projects stored locally. Vidulk's Android app is the same product as on iPhone and the web, with one account.

Captions is far ahead on generative AI: avatars, dubbing, lip sync and generated media. Vidulk has none of these. If you want AI to clip long recordings and style the captions, try Vidulk at vidulk.com/app.

Who should pick which

Choose Captions if you record talking-head videos, ads or UGC on your phone and want AI to edit, translate or even generate them. Choose Vidulk if you already have long content, such as podcasts, streams, interviews or YouTube videos, and need it cut into many short clips each week.

Captions lists captions in 100+ languages and 100+ caption templates on paid plans. Vidulk has 65 caption styles with custom fonts, colors, highlights and animations. Vidulk credits never expire, so occasional use costs $7 per video rather than a monthly plan.
