DubFlow — User Guide
Version 1.4.32 · Updated 5 October 2026
DubFlow lets you enjoy any video in the language you choose — the video plays out loud in your language while you watch. This guide walks you through everything, from installing it to getting the most out of your voice and plan.
1. What DubFlow does
Open a video on a site you already use, choose the language you want to hear, and press play — you'll hear it spoken in that language while you watch. No downloads of the video, nothing to re-upload.
- Watch anything in your language — foreign films, shows, clips, anime, K-dramas, C-dramas, telenovelas, and more.
- Hands-free — listen instead of reading along.
- Pick your voice and speed — tune it to what sounds best to you.
- Works where you already watch, right in your browser.
- Free every day, with simple paid upgrades.
- Private — your settings stay on your device.
2. Install
- Add DubFlow to your browser (Chrome, Edge or another Chromium browser). You can install it from the store listing or from our website.
- You'll see the DubFlow icon appear in your browser toolbar.
- No account is needed for the free plan.
On some sites you may be asked to allow DubFlow on this site — click Enable once and it works there from then on. Popular video sites are already enabled out of the box.
3. Dub your first video
- Open a video on any supported site and start it playing.
- Click the round Dub button that appears on the video (bottom-right). It turns on dubbing for that video.
- Prefer the toolbar? Click the DubFlow icon and choose your Language and Voice, then start dubbing.
- That's it — sit back and listen.
You can also open DubFlow's settings any time from the small gear icon next to the on-video button.
4. The status light
The light on the on-video button tells you what's happening at a glance:
| Colour | Meaning |
|---|
| Grey | Idle — ready when you are. |
| Yellow | Loading — getting ready and connecting. |
| Green | Playing — the dub is live. |
| Red | Something's not working — check that the video is playing with sound, or reload the page. |
The label above the button shows the current state too (for example, "Dub ready" or "Dub on — Spanish").
5. Settings explained
| Setting | What it does |
|---|
| Language | The language you want to hear. It defaults to your browser's language; change it anytime. |
| Voice | The voice used for that language. Only voices for your chosen language are shown, so you always get a matching one. |
| Voice speed | How fast the voice speaks. Higher is quicker. |
| Original audio volume | How loud the video's original audio stays underneath the dub. Lower it to focus on the dub. |
| Auto-fit voice speed | Keeps the dub in step with the video — it gently adjusts so you don't miss words. |
| Mute the original audio | Silences the original audio completely. |
6. Change language or voice anytime
Open the settings (gear icon on the video, or the toolbar popup) and pick a different Language or Voice — it applies live, no reload needed.
7. Free & paid plans
| Plan | Price | What you get |
|---|
| Free | $0 | Up to 3 hours of dubbing a day, one language. No account needed. |
| Basic | $9 / month | Unlimited dubbing, one language. |
| Pro | $19.99 / month | Unlimited dubbing, all languages. |
| Lifetime — one language | $79.99 once | Own it, one language. |
| Lifetime — all languages | $199 once | Own it, every language. |
The free allowance resets every day.
8. Licence keys
- After you buy a plan, we email you a licence key.
- Click the DubFlow icon in your toolbar, paste the key into the License key box, and press Save license.
- Your plan unlocks instantly — no account or sign-in required. The key is checked on your device, so it keeps working offline.
You can use your key on devices you own or control. Please keep it private — keys shared publicly may be deactivated.
9. Share & earn
Invite friends and earn free months. In DubFlow's settings you'll find Share & earn with your personal referral link and one-tap share buttons for your favourite apps.
- You earn 1 month free when a friend joins and uses DubFlow.
- You earn a 2nd month free when they subscribe.
- Rewards are added as free months on your plan.
10. Your account & referrals
An account is optional — the free plan works without one. If you sign in, you can see your referral status and rewards on your account page.

11. Tips & supported sites
- DubFlow works best on videos that play openly on the page.
- On embedded players, the on-video Dub button is often the most reliable control.
- Make sure the video is actually playing with sound before you start.
- If a site isn't supported yet, you can enable DubFlow there with one click, and tell us the page so we can add it.
12. Troubleshooting
The light is red
- Make sure the video is playing and has sound.
- Reload the page and start the dub again.
- If it still fails, tell us the site and browser and we'll help.
I don't hear anything
- Check your device volume and that the video isn't muted.
- Lower Original audio volume so the dub is easier to hear, or turn on Mute the original audio.
- Start the dub while the video is playing.
The voice sounds too fast or too slow
- Adjust Voice speed to taste; keep Auto-fit voice speed on for the best match.
I can't pick a voice for my language
- The voice list shows voices for your chosen language — pick the language first, then the voice.
13. Privacy & support
DubFlow respects your privacy — it doesn't record your videos and doesn't sell your data. See the Privacy Policy for details.
