Subcap
Phone-first AI captioning app that writes synced subtitles and shows two languages on screen at once
Choose Subcap if you publish short-form video entirely from your phone and want two languages burned into one export. The bilingual on-screen display is the reason to pick it over generic phone caption apps, and the style controls draw consistent praise in the testimonials on the site — a video editor quoted there changes size, font, colour and position and says it handles German and his mumbling well. Do not buy it as an editor replacement: there is no timeline, no team workspace and no desktop counterpart on the site, so long-form multi-speaker post-production belongs in a browser suite like Kapwing or VEED.io.

Skip Subcap if you need a timeline — cutting, colour, multi-clip assembly or multi-speaker long-form post-production — rather than subtitles for an already-finished clip.
On the Free plan, exported videos carry a watermark according to the plan description, so every clip you publish publicly needs the paid tier first.
Subcap prices as a consumer phone app rather than a seat-based studio subscription, which puts it in the same bracket as other single-purpose mobile caption tools and well below browser suites like Kapwing or VEED.io where you pay for a timeline and team seats you may never use from a handset. The Pro tier is the one that carries the bilingual overlay and styling.

About Subcap
Subcap is a mobile captioning app for iOS and Android. You shoot a clip inside the app or pull one from your gallery, and Subcap transcribes the spoken audio into subtitles that are aligned to the words — the vendor says captions are ready in seconds, and that alignment holds through pauses, fast speech and background noise. The distinguishing feature is the dual-language view: Subcap translates captions into more than 100 languages (the site says 125 in one place and "over 100" in another) and can display two languages on screen in the same video, so one export serves your local audience and an international one. Styling is editable — font, colour, size and position — and there is a manual editor for fixing the words any speech-to-text engine gets wrong, plus the ability to add captions by hand. Video exports at 720p or 1080p with captions burned in, caption text can be copied out for reuse, and finished clips can be shared from the app. Everything happens on the handset: there is no desktop or browser workspace described anywhere on the site. The vendor's "only true 99% accuracy in the mobile app industry" line is a self-reported marketing claim, not a benchmark, and one reviewer on the site says plainly that there is a little editing to do because the AI isn't 100% accurate. Subcap captions video; it does not cut, grade or assemble it.
Behind the Verdict
Subcap's case rests on two things a browser suite does badly on a phone: speed of getting from clip to captioned export, and the dual-language overlay. What it does well. The workflow is short by design — shoot in-app or import from the gallery, let the app transcribe and align, restyle, export at 720p or 1080p. Timing is automatic, and the vendor claims alignment survives pauses, fast speech and background noise. The bilingual feature is genuinely differentiated at this price point: rather than exporting twice for two audiences, you put both languages on screen at once. Caption styling (font, colour, size, position) is exposed rather than hidden behind a preset, which matters if you want a house look. Caption text can be copied out and reused as a post description, and the app has a manual editor plus hand-added captions for the words the engine misses. Where it is thin. It is a captioner, not an editor — no cutting, no colour, no multi-clip assembly. It is phone-only: no desktop or browser workspace is described on the site, so a laptop-first pipeline starts somewhere else. Accuracy is the vendor's own claim — the homepage's "only true 99% accuracy in the mobile app industry" is marketing copy, and one of the testimonials printed on that same homepage concedes the AI is not 100% accurate and needs a short edit. A different testimonial references a past update that broke millisecond display, which is a reasonable reminder that small display details can shift between versions. The free tier's exports carry a watermark according to the plan description in our seed data; the plans page was not reachable for this refresh, so confirm current terms inside the app before you commit a publishing schedule to it. Where it fits. Solo short-form creators on TikTok, Reels and Shorts; students captioning presentations and lecture recordings; small businesses making accessible marketing clips without touching a laptop; anyone whose audience spans two languages and who wants both visible in a single cut. Where it doesn't. Teams doing long-form or multi-speaker post-production, desktop-first editors who want a browser timeline and shared seats, and developers who need to call a captioning engine from their own pipeline. Against Kapwing or VEED.io, Subcap wins on phone-native speed and the dual-language overlay and loses on everything timeline-shaped.

Real-world workflow fit
Concrete scenarios for the personas Subcap actually fits — and what changes day-one when you adopt it.
You shoot a 40-second clip in the Subcap app, let it transcribe and auto-sync, restyle the captions to your usual font and colour, then export at 1080p with captions burned in and share straight from the phone.
Outcome: A publishable captioned clip without opening a laptop or timing a single subtitle by hand.
You import a recorded class presentation, generate captions in English, add a second language so international classmates can follow, then fix the handful of words the engine got wrong in the manual editor.
Outcome: An accessible version of the presentation that works for a mixed-language class, produced on the device you already had with you.
You record a short product demo, generate subtitles, copy the caption text out to reuse as the post description, and export at 720p for social.
Outcome: An accessible marketing clip and its post copy from a single pass, with no desktop editor involved.
Use Cases
- Caption a TikTok or Instagram Reel straight from your phone
- Publish one video with English and a second language shown together
- Add accessible subtitles to a class presentation or lecture recording
- Translate a product demo for an audience in another market
- Style and export a captioned clip without opening a desktop editor
- Copy the caption text out to reuse as a post description
Limitations
- Subcap is positioned as a phone app — no desktop or browser workspace is described on the site, so if your pipeline starts on a laptop this is not the tool.
- It captions video, it does not edit it: no cutting, no colour work, no multi-clip assembly.
- The accuracy figure the vendor publishes ("the only true 99% accuracy in the mobile app industry") is a self-reported claim, not a third-party benchmark, and a testimonial printed on the same homepage concedes the AI isn't 100% accurate and needs a short edit.
- The site itself is inconsistent on language count — "over 100 languages" in most places, "125 languages" in another — so treat both as approximate.
- Testimonials also reference a past update that dropped millisecond display, a reminder that small details can shift between versions.
- Free-plan exports carry a watermark according to the plan description in our records; the plans page could not be reached for this refresh, so verify current terms in the app before relying on them.

Free
$0
Ideal for
Creators testing whether phone captioning fits their workflow before paying, and students captioning the occasional class clip.
What this tier adds
Starting tier: in-app capture or gallery import, AI transcription and auto-sync, manual subtitle editing, and sharing — with a watermark on exports per the plan description.
Pro
Contact for pricing
Ideal for
Short-form creators and small businesses publishing regularly enough that a watermark and single-language captions are no longer acceptable.
What this tier adds
Adds the bilingual two-language overlay, translation into 100+ languages, full style controls (font, colour, size, position), and burned-in 720p/1080p export.
Where the pricing makes sense
The company stage and team size where Subcap's pricing actually pencils out — and where peers do it cheaper.
Subcap prices as a consumer phone app rather than a seat-based studio subscription, which puts it in the same bracket as other single-purpose mobile caption tools and well below browser suites like Kapwing or VEED.io where you pay for a timeline and team seats you may never use from a handset. The Pro tier is the one that carries the bilingual overlay and styling.
Setup time & first value
How long it actually takes to get something useful out of Subcap — broken out by persona, not the marketing-page minute.
Expect minutes, not days: install the app, shoot or import one clip, and the vendor says captions arrive in seconds. Short-form creators reach a first publishable export in under ten minutes; students and small-business owners should add a short proofread pass in the manual editor before the first real export, since the vendor's own testimonials concede the AI isn't perfect.
Switching to or from Subcap
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual caption typing in a phone editor: import the raw clip into Subcap and let auto-sync replace hand-timed subtitles.
- →From a browser suite like VEED.io: keep long-form work there and move only the phone-shot short-form clips to Subcap.
- →From CapCut's auto-captions: import the finished clip and use the dual-language view when you need a second on-screen language.
- →From a generic transcription app: paste-free path — Subcap transcribes from the video itself and burns captions in on export.
- ↗To Kapwing or VEED.io: export the captioned video, then rebuild anything needing a timeline or team seats in the browser suite.
- ↗To CapCut: move the raw footage across and re-run auto-captions if you need editing tools Subcap does not have.
- ↗To a desktop NLE: export at 1080p with captions burned in, or copy the caption text out and re-time it in the editor.
