Burned in, not attached
The captions are rendered into the frames, so they survive the upload and every viewer sees them without switching anything on.
Submagic alternative
A browser-based tool for short-form creators: it captions clips, cuts long videos into shorts, and adds B-roll and sound effects, on a per-seat monthly plan.
Capster is an iPhone app that does one job: it transcribes a clip, lets you style the captions, and exports a video with them burned in. If you need more than captions, Submagic is the larger product. If captions are the job, this page is the case for the smaller one.

Source: Submagic's prices come from Submagic's own pricing page, read in September 2026. Capster's come from this site's pricing page, which is generated from the same file the App Store listing is checked against.
There is no ratings column. Capster shipped in September 2026 and its App Store listing has no reviews yet, so a ratings row would be an empty cell next to a large number — which tells you about age, not about captions. Language counts are left out for the same reason: the two products count them differently and a bare number would compare nothing.Capster transcribes 99 languages and detects them automatically; which fonts render which scripts is the part that actually affects your export.
Not a formality. These are the reasons to pick Submagic over Capster, and if one of them describes your work, pick Submagic.
A browser-based tool for short-form creators: it captions clips, cuts long videos into shorts, and adds B-roll and sound effects, on a per-seat monthly plan.
The captions are rendered into the frames, so they survive the upload and every viewer sees them without switching anything on.
The preview runs the same renderer as the export, so the caption you place is the caption in the file.
There is no sign-in. The video itself is never uploaded — only its audio track goes out for transcription, and the provider deletes it afterwards.
Finish the cut wherever you already cut it, captions off, and save it to your camera roll.
Import from Photos. The audio transcribes in the background; the language is detected, so there is nothing to pick.
A style applies to every caption in the clip at once. Export gives you one finished file, ready to post.
Cancelling Submagic is done wherever you subscribed to it, not in this app — if you subscribed on an iPhone, that is Settings, your name, then Subscriptions.
It is if captions are the only thing you need. Capster does one job — transcribe a clip, style the captions, burn them into the file — on the iPhone, with no account, for $29.99 a year. Submagic is a bigger product and costs more because of it.
Starter $19/month, Pro $39/month, Business + API $69/month (billed yearly: $12, $23 and $41/month). That is the list price on Submagic's own pricing page as of September 2026. Capster is $6.99 a month or $29.99 a year, with a 3-day free trial on the yearly plan. Prices change, so check both before you decide.
Yes, and you can export for free. The free tier gives you 5 transcriptions per install, clips up to 2 minutes, and 2 caption styles. Exporting is never blocked — free exports carry a small badge and a short end card instead.
No. It produces one finished video with the captions rendered into the frames, which is what social platforms need. If you need an SRT or VTT file to hand to someone else, that is a real reason to use something else.
