Definition
Auto-generated captions use AI speech recognition (ASR / speech-to-text) to automatically transcribe spoken audio in a video and generate synchronized caption/subtitle tracks. Modern auto-captioning supports multiple languages and accents, speaker attribution, punctuation, and timing alignment. Captions are essential for accessibility compliance (ADA, WCAG), social media engagement (85% of Facebook videos are watched without sound), SEO (search engines index caption text), and reaching non-native speakers.
How Loopdesk Uses This
Loopdesk provides AI-powered auto-captioning in 57 languages with high accuracy across accents and dialects. The free tier includes 50 minutes of AI caption generation, while the Creator plan offers unlimited captions. You can customize caption styling (font, color, size, position, animation), review and edit generated text before export, and choose from various visual styles. Captions are fully synchronized to your timeline and update automatically when you make edits.
