Watch any English lecture in Arabic

Paste an English lecture link and watch it with a synchronized Arabic voice, plus a summary, key terms, an AI assistant and a quiz. Technical terms stay in English.

Why not use YouTube’s auto-dubbing?

It only exists when the creator enables it, most lectures don’t have it, and it hides the English terms. With Dubljly you choose the video and learn the terms instead of losing them.

Do you republish the video?

No. The original video plays from YouTube’s own player, and we add a synced Arabic audio track on top for personal study.

How good is the translation?

We translate with the context of the whole lecture, keep a fixed glossary of terms, and write each sentence to fit the speaker’s timing.

Which Arabic do you use?

Simplified Modern Standard Arabic that everyone understands, with a Jordanian voice. Dialect choice is on our roadmap.

What are the video limits?

English lectures up to 20 minutes, from YouTube links or mp4, mov and mkv files up to 200 MB.
