Your video is processed in this tab and never uploaded to a server.

Caption as many videos as you like. No caps, no paywall, no login.

How it works

A subtitle generator that keeps you in control

Typing subtitles by hand is slow, and most auto-caption sites make you upload your video first. VidTools reads the file locally, transcribes the speech, and splits it into properly timed lines you can edit before exporting. Nothing leaves your device, and you get clean SRT or VTT files ready for any editor.

Edit before you export

Automatic captions get you 95% of the way there. VidTools lets you fix a name, merge a line, or shift a timing so the final file is exactly right.

SRT and VTT, ready to drop in

Export the standard formats every editor and platform understands, then attach them to your video or upload them alongside it.
