Zubtitle

Zubtitle is an AI-powered online video editing platform built to help creators, marketers, and businesses add automatic captions and subtitles to their videos in minutes. The tool uses advanced speech-to-text technology to transcribe spoken audio and convert it into accurately timed open captions that can be burned directly into video exports. Beyond captioning, Zubtitle provides a full suite of social video optimization features including multi-platform video resizing and cropping, headline text overlays, animated progress bars, custom branding with uploaded logos, and styled caption animations. The platform also integrates AI-driven content generation capabilities, enabling users to automatically produce social media post copy, relevant hashtags, video summaries, and descriptions pulled directly from their video content.

Zubtitle supports uploads in MP4, MOV, and M4V formats with resolutions up to 4K and durations of 20 minutes or less. Its browser-based interface is fully accessible on desktop and mobile devices, eliminating the need for complex professional editing software. Users can export finished videos with embedded captions or download standalone SRT and TXT transcript files for accessibility compliance and SEO repurposing. Zubtitle operates on a freemium pricing model with cost-effective plans suited for individual creators, coaches, podcasters, and digital marketing agencies managing multiple client accounts.
