Dubs any video in your tab into Persian in real time. Auto-detects the language. Uses your own Gemini API key.
Doblaj listens to whatever is playing in your browser tab, works out what language it
is on its own, and speaks it back to you in Persian a few seconds later.
No subtitles to read. No files to prepare. No source language to choose.
HOW IT WORKS
Doblaj streams your tab's audio to Google's Gemini Live Translate model over a single
open connection. Because nothing waits for a sentence to finish before being processed,
Persian audio starts coming back within a few seconds rather than the twenty or thirty
that chunk-by-chunk tools need. The original audio ducks underneath the dub and lifts
again when the line ends.
Each speaker keeps their own pitch and pacing, so men and women still sound like men
and women without you configuring anything.
WHAT YOU NEED
A free Gemini API key from Google AI Studio. You paste it into the extension's settings
once. You are billed by Google for what you dub, on your own account — there is no
subscription, no middleman, and no account to create with us.
WORKS ON
YouTube, Twitch, Aparat, news streams, podcasts, lecture recordings, and ordinary
embedded video. Protected audio from DRM services such as Netflix cannot be captured by
any extension, so those are out.
Over 70 source languages, detected automatically. A video that switches language
midway is handled without you touching anything.
SAVE THE RESULT
Live playback is always a beat behind — that is inherent to dubbing anything live.
So Doblaj also records the session on the video's own timeline, where every line sits
exactly where it belongs, and lets you download:
• Dubbed mix (WAV) — the original ducked under the Persian dub, levelled and normalised
• Dub only (WAV) — Persian speech over silence, if you would rather mix it yourself
• Persian subtitles (SRT) — every line with real timings
The settings page shows an ffmpeg command for putting the audio back onto your video.
SEE WHAT IT IS DOING
A dashboard tracks minutes dubbed, API calls made, characters spoken, detected
languages and sites dubbed, so your Google bill never surprises you. Export it as JSON
or reset it with one button. A diagnostics log shows every stage of the pipeline, and
a one-click connection test confirms your key works before you start.
