AI dubbing & study tools
Reach students in more languages, and turn a lecture into revision material — without recording anything twice.
These features cost money per use
AI actions are charged from your AI wallet based on what they actually consume, not bundled into your plan. Every button shows an estimated cost before you click it. Top up under Billing.
Two things you need first
1. Set the spoken language on the video
The AI needs to know what language it is listening to. Set it at upload time, or on the video page afterwards. Nothing else will run until this is set.
2. Have wallet balance
Every AI button is disabled at zero balance, with a link to recharge.
Subtitles from your audio
There are two transcription options, and they produce different things.
| Action | Produces | Use when |
|---|---|---|
| Transcribe to English | An English caption track, translating as it goes | Your lecture is in Hindi or another language but you want English subtitles — and to unlock the study tools |
| Transcribe to spoken language | A caption track in the original language, word for word | You want same-language subtitles for accessibility or noisy environments |
English captions unlock everything else
Study notes, quizzes, flashcards, mind maps and the difficulty rating all read the English track. If you plan to use any of them, transcribe to English first.
Translating and dubbing
Once a lecture is transcribed you can take it into another language two ways.
- Translate (text only) — subtitles and chapter titles in the new language. Cheaper, and often enough.
- Full dub — a synthesised soundtrack in the new language, added as an alternate audio track students can switch to.
Languages and voices
Twenty target languages are available, split between Indian and international. The voice provider is chosen for you based on the language: Indian languages use a provider with a wide range of natural Indian voices, while other languages use a multilingual provider. If you have cloned a voice under Settings → Speaker profiles, it appears in the list too.
Keeping technical terms in English
The code-switchingtoggle keeps technical vocabulary in English inside otherwise translated speech — so a Hindi dub of a physics lecture still says “acceleration” rather than an unfamiliar translation. For most Indian coaching content this matches how teachers actually speak.
While a job runs
Dubbing runs in the background through Queued, Transcribing, Translating, Synthesizing, Processing and Ready. A long lecture takes a while — you can leave the page and come back.
Regenerating replaces and recharges
Regenerating a dub deletes the existing audio track and charges again. You will be asked to confirm, with the cost shown. Captions are left alone.
Study material
All five are generated from the English caption track, appear inside the player for students, and can be regenerated if you are not happy with the result.
| Tool | What students get |
|---|---|
| Chapter notes | A summary per chapter plus an overview. Downloadable as a branded PDF. |
| Quiz | Six to eight multiple-choice questions, opening automatically when the lecture ends. |
| Flashcards | Ten to fifteen question-and-answer cards for revision. |
| Mind map | A visual hierarchy of the concepts covered. |
| Difficulty rating | Beginner, Intermediate or Advanced, with a reason. |
Check before publishing
These features are in beta. The AI works from the transcript, so if the transcription misheard a technical term the notes will repeat the mistake. Read through anything students will be assessed on.
Vocabulary and glossaries
Assign a subject glossary to a video and defined terms pop up with a short definition as they are spoken. Useful for technical subjects, and for students studying in a language that is not their first.
Keeping costs predictable
- Every action previews its cost before you commit.
- Charges are based on lecture length, so long videos cost more.
- Text translation is considerably cheaper than a full dub.
- Try one lecture end to end before processing a whole course.
