Kiwify Video Translator hear any course in your language — even one with no captions at all.
DubTab is a Kiwify translate extension that works in real time: it listens to the lesson and speaks it in English or your language with an AI voice, while translated captions follow on screen. Kiwify's own player or a YouTube video inside the course, on Kiwify or on the producer's own site — and no captions needed, which is just as well, because Kiwify doesn't add any.
Free 15-minute trial · No credit card · Works on any Kiwify members area
What Kiwify gives you is the producer's video. Nothing on top of it.
A Kiwify lesson plays the way the producer uploaded it: Kiwify's player doesn't generate captions, let alone translate them. If the producer didn't add captions, there are none — and most Kiwify courses are taught in Brazilian Portuguese.
So you pause, rewind ten seconds, paste a phrase into a translator, lose the thread. A one-hour module takes two — and the half you didn't catch is usually the half you paid for.
The Kiwify app plays lessons offline and on a TV, and some courses open on the producer's own site rather than on Kiwify — but nowhere in that chain does anything translate a word.
An AI voice speaks the lesson in your language while the video plays; translated captions are one click away when you'd rather read along. The producer's own voice stays underneath, at a volume you set.
DubTab listens to the audio, not to a caption file — so a lesson with no captions at all, a YouTube video embedded in the classroom, or an audio-only lesson all work the same.
It follows the tab, not the address: on Kiwify or on the producer's own site, Kiwify's player or a YouTube live inside the course — open it in Chrome and turn it on.
Translate a Kiwify course in 3 clicks
1. Add DubTab to Chrome
One click from the Chrome Web Store — the free trial is included.
2. Open the lesson in your members area
Click the access link from your purchase email and open the lesson as usual — in Chrome, not in the Kiwify app.
3. Turn on dub & captions
Pick your language once. The AI voice and translated captions start within seconds.
Built for courses that come with no captions at all
Real-time AI dubbing
The voice speaks while the video plays — not a file you upload and wait for. A 40-lesson course works the same as a five-minute welcome video, and the producer's own voice stays underneath at a volume you set.
No captions needed
Kiwify's player doesn't generate captions, and DubTab doesn't need them — it listens to the lesson's audio. Portuguese, Spanish or English producer, the spoken language is detected automatically.
Bilingual captions
Translated captions alongside the original, or your language alone. Read along with the dub, or use captions on their own — both follow the lesson live.
Any Kiwify members area
Whether your course opens on Kiwify or on the producer's own site, DubTab follows the audio in your tab — it never checks the address.
Stays in sync automatically
Auto catch-up keeps the dub aligned with the video, so the voice never lags behind the producer — even after you scrub back to catch a step.
Hosted video, YouTube embed, live or audio
Kiwify hosts the producer's videos, lets them embed YouTube — including YouTube lives — and add audio lessons. DubTab dubs whatever is playing in the tab, whichever of those it is.
What people learn on Kiwify with DubTab
Kiwify is where Brazilian creators sell their courses — taught in Portuguese, often over a shared screen or a fixed camera, fast and full of slang — and it's sold well beyond Brazil. That's exactly where a voice in your language beats a caption bar that isn't there.
Digital marketing and paid traffic
Ad management, funnels, launches, affiliate playbooks — the courses that put Kiwify on the map, taught over a shared screen where the cursor is the lesson.
Beauty, lashes and nails
Lash extensions, nail design, micropigmentation, hair — close-up, hands-on demos where every second on a caption bar is a second not watching the technique.
Baking, cooking and crafts
Cakes, sweets, bread, crochet, resin — recipe-driven lessons where quantities and timings need to land exactly, in your language.
Finance, investing and trading
Personal finance, stocks, options and crypto — jargon-heavy, chart-on-screen lessons where the dub carries the terms while you watch the setup.
Fitness, nutrition and health
Training programs, weight loss, physiotherapy, aesthetics — follow the cues in your language without looking away from the movement.
Exams, languages and everything else
Exam prep, language courses, music, faith, personal development — Kiwify's catalog goes wherever a creator does, and every lesson plays in the same members area. Same DubTab, same three clicks.
Doesn't Kiwify translate courses — or at least caption them?
No. Kiwify's player plays the video the producer uploaded, with nothing added: no automatic captions, no translation, no dub. Whether a lesson has captions at all is up to the producer; Kiwify's own Help Center covers uploads, the app and YouTube embeds, and has no article on captions. Everything else — your language, as a voice, on every lesson — is what DubTab adds.
| Where the lesson lives | Captions you get | DubTab |
|---|---|---|
| Video hosted by Kiwify | None from Kiwify — the video plays as the producer uploaded it | ✓ Real-time dub + captions in your language, 60+ languages |
| YouTube video embedded in the members area | YouTube's own auto-captions, if the uploader left them on — Kiwify adds nothing | ✓ Same — works from the audio, not the captions |
| YouTube live embedded in the members area | No translation — Kiwify has no live feature of its own | ✓ Real-time, as the live plays in your tab |
Kiwify's Help Center covers uploads, the app and YouTube. Not captions.
That silence is the whole picture: the player has no caption or translation feature to document. A lesson arrives with the language the producer spoke, and that's it. DubTab doesn't work from a caption file — it listens to the producer and speaks your language, on every lesson, in every members area.
Your course may not even open on kiwify.com.
Some producers run their members area on their own site, and the access link in your purchase email takes you straight there. That doesn't matter to DubTab: it follows the audio playing in your browser tab, not the address. Kiwify's player or a YouTube video inside the course — same three clicks.
You bought a Brazilian course. It didn't change language at the border.
Kiwify sells to creators in English and Spanish too, and Brazilian producers sell far beyond Brazil — but the lessons are still recorded in Portuguese, fast and full of slang. DubTab is the layer the purchase didn't come with: the producer's voice, in your language, live, with the original still audible underneath.
