Captions timed from your video's own audio, shown on the picture before you download. Watching every cue is free. One credit downloads the SRT and VTT.
Drop a reel, a TikTok, a Short, a YouTube video or a course recording. The sound is decoded in your browser and sent as plain audio; the video itself never leaves your device. Cues appear on the video as it plays, built under the rules platforms and editors expect: one or two lines, a character budget per line, no cue on screen longer than a few seconds, breaks that never split a word. Click a cue to jump there, double click to fix a name, switch between a one line social layout and a two line standard layout.
Everything you see is free. One credit downloads the SRT, VTT and text files for the video, and you can download again after every correction. No watermark, no editor to learn, no subscription.

Why the line rules matter
A caption that runs to three lines covers the speaker's face on a phone. A cue that stays for nine seconds is read twice and then ignored. A line broken in the middle of a name reads as a mistake. Broadcast captioners settled these rules decades ago: at most two lines, around forty two characters each, roughly one to six seconds on screen, breaks at natural phrase boundaries. Social video tightened it to one short line at a time. The cues here are built to those rules from the word timings, not chopped at a fixed count, which is why they read as intended rather than as a transcript poured into boxes.
