Why it matters

80% of social video is watched without sound

Captions aren't a nice-to-have — they're how your message gets through. Professional captions improve accessibility for deaf and hard-of-hearing viewers, boost SEO with searchable text, increase watch time by 12%, and satisfy platform algorithms that reward captioned content with higher reach. Every major creator and brand uses them.

Styles

Match your brand. Stand out in the feed.

Every style is fully customizable — colors, fonts, size, position, animation.

Viral Pop

Bold, bouncy, color-shifting. The style that dominates TikTok and Reels. Word-by-word highlighting with scale animation.

Broadcast

Clean, professional, lower-third positioning. Network news quality. Perfect for corporate content and presentations.

Gradient Wave

Smooth color transitions across words. Eye-catching without being distracting. Great for lifestyle and travel content.

Outline Bold

Thick outlined text that pops on any background. High contrast, high readability. Works on bright and dark footage.

Typewriter

Character-by-character reveal with cursor. Builds anticipation. Perfect for storytelling, tutorials, and dramatic moments.

Karaoke

Progressive word highlighting synced to audio. Viewers follow along naturally. Ideal for music, poetry, and educational content.

Cinematic

Subtle, elegant, centered. Thin weight, generous spacing. For premium content that doesn’t want captions to dominate the frame.

Minimal

Clean sans-serif, bottom-aligned, no effects. Maximum readability, minimum distraction. The choice when content speaks for itself.

Accessibility

Reach every viewer

Accessible video for all viewers
“We switched from manual transcription to Envizion AI captions. What took our editor 3 hours per video now takes 30 seconds. And the styles actually look better than what we were making by hand.”
