Everything runs 100% locally, no API key needed. Subtitles & translation are free — dubbing requires a license.

3 tools · 1 app

Three workspaces for every AI video job

Switch between modules right from the sidebar — everything runs 100% locally.

① Translate & Dub

Paste a URL or upload → transcribe → translate into Vietnamese → dub with a studio-grade HD voice (or your cloned voice) → burn in subtitles → export 16:9 / 9:16.

② Cut Clips & Titles

Automatically finds the "clip-worthy" moments in long videos → exports multiple short clips and auto-generates titles from the content.

③ Script → Video

Type a topic or script → AI directs the scenes, builds vector motion graphics + Vietnamese narration. Explainer videos on autopilot.

New · Chrome extension

Translate & dub YouTube as you watch

Install the Chrome extension → open any YouTube video → turn on Vietnamese subtitles + HD-voice dubbing right in the browser, no download required. Subtitles are free; dubbing uses HD voices (license required).

Live Vietnamese subtitles

AI listens to the speech, then translates & displays synced Vietnamese subtitles — even when the video has no captions at all.

HD-voice dubbing

Reads over the video in a Vietnamese HD voice, with adjustable original-audio volume — like listening to a Vietnamese podcast.

1-minute setup

The extension ships with the app → enable it in Chrome → done. Runs alongside the local app on your machine.

VoiceForge Vietnamese voice library + Voice cloning

6 studio-grade HD voices (Northern & Southern accents, male & female) — natural delivery that keeps one consistent voice across the entire video, even volume, no dropped lines. Plus voice cloning: record 5 seconds of your voice and the AI narrates the whole video in it. Want more? Bring your own API key (BYOK) to unlock 9 Vietnamese FPT.AI voices (free 100k characters/month) + 6 English ElevenLabs voices — paste a key and the voices simply appear.
