Hi Product Hunt — I'm the maker of SubtitlePop.
Automatic captions still need a human pass. A name can be wrong, a line can break in an awkward place, or the words can cover the part of the picture you want people to see. SubtitlePop keeps that editing step in the same workflow as generation and export.
Upload a video or audio file, generate word-timed captions, and check the text in the editor. You can adjust timing, split or merge lines, and choose from 12 caption styles, including word highlights and one-word pop captions. Export a captioned MP4, or take SRT, VTT, ASS or TXT into another workflow.
If you already have subtitles, the free file tools handle conversion, timing shifts and error checks without an account. Those tools process subtitle files in your browser. Automatic transcription uploads the audio track; burning captions into an MP4 uploads the video for rendering.
There is a free plan for trying the workflow. Its video exports have a watermark and resolution and daily limits. Paid subscriptions and one-time minute packs are available for more work.
I'd especially like feedback from people making Shorts, Reels and tutorials: what do you usually fix first after generating captions — the wording, the timing, or the line breaks?
