Zubtitle

Zubtitle is an AI tool that captions and branded video edits built for talking-head social clips. Browser-based video editor for talking-head clips: automatic captions, editable transcripts, headlines, logos, brand templates, and one-click resizing into square, vertical, or widescreen formats for social platforms.

Zubtitle is a browser-based video editor built around one job: turning a single talking-head recording into a finished, captioned post for social feeds. The workflow starts with an upload. The service transcribes the speech, generates timed captions automatically, and drops them onto the video. From there the transcript can be cleaned up word by word and the timing adjusted, which matters for creators whose unscripted delivery includes false starts and filler. Around the caption layer sits a light set of editing tools aimed at people who do not want to learn a professional timeline editor. Headlines can be placed above or over the footage to frame the point before a viewer scrolls on. Logos and watermarks go on with drag and drop. Cropping and resizing reframe the same clip into square, vertical, or widescreen versions so it fits each platform without a rebuild. Trimming, progress bars, saved brand templates with custom fonts and colors, and a library of ready-made templates round out the package. Captions can also be produced in foreign languages, and a .txt or .srt transcript file can be downloaded for each processed video. The product is aimed squarely at coaches, creators, and small teams who publish video but do not have an editor on staff. Zubtitle makes its own case with the mute-viewing statistic: most social video is watched with sound off, so burned-in text is the hook. Its pitch against alternatives is speed and simplicity rather than depth. Freelance transcribers and virtual assistants cost more per video by Zubtitle's own comparison, and full nonlinear editors carry a learning curve this tool deliberately avoids. The tradeoff is that anyone needing multicam work, advanced color, or layered compositing will outgrow it quickly. Upload limits are the practical boundary to check before committing. Files must be .mp4, .mov, or .m4v under 1 GB, H.264 encoded (H.265 only in Safari), no larger than 4096x2160, and 20 minutes or shorter. The editor runs in the browser and is mobile friendly on iOS and Android, with no credit card needed to start.
