Every Tool You Need
to Go Global
One platform. Multilingual dubbing, AI voices, voice cloning, subtitle generation, and a full video editor — built for creators who refuse to be limited by language.
Turn Any Video Into 104+ Languages. Automatically.
Upload your video and our AI handles everything — transcription, context-aware translation, and natural-sounding audio output. No voiceover studio. No translators. No waiting weeks.
-
AI Transcription + Translation — Whisper-powered audio extraction with context-aware neural translation that preserves idioms, tone, and intent across 104+ languages.
-
Multi-Shot Script Review — Review every translated segment before rendering. Regenerate individual lines with one click. Full control before committing to audio.
-
Lip-Sync Aware Timing — Dubbed audio is timed to match the original speaker's pacing. No jarring gaps. No mismatched mouths.
2,600+ Neural Voices That Sound Genuinely Human
Powered by enterprise-grade neural TTS engines used by Fortune 500 companies. Choose from 2,600+ voices across 104+ languages, then fine-tune emotion, pace, and style per segment.
-
Emotion & Style Control — Set speaking style (newscast, cheerful, empathetic, excited) and adjust rate and pitch per voice segment for nuanced, natural delivery.
-
Premium Neural Voices — Multi-engine access. Pick whichever voice fits your content best — or run both and A/B test. Never locked to a single engine.
-
One-Click Voice Preview — Audition any voice directly inside the editor before committing. Hear exactly how your script sounds with each voice — before spending a single credit.
Your Voice. Every Language. Instantly.
Record just 30 seconds of audio and our AI clones your voice for all dubbed versions. Your Spanish audience hears you — in your own voice. Your Japanese viewers hear you too. Powered by advanced AI voice cloning technology.
-
30-Second Clone — Upload or record a short reference clip. Our system extracts your voice fingerprint and applies it across every dubbed language track.
-
Instant vs. High-Fidelity Modes — Choose Instant mode for fast turnaround, or High-Fidelity mode when you need broadcast-quality output that's indistinguishable from studio recording.
-
Reuse Across All Projects — Save your cloned voice to your library. Apply it to any future project in one click — no re-recording required.
Multiple Speakers. Each Gets Their Own Voice.
Interviews, podcasts, panel videos, webinars — our AI automatically detects every unique speaker in your video and assigns them a distinct dubbed voice. No manual labeling. No timeline nightmares.
-
Auto Speaker Diarization — AI identifies each unique speaker from audio alone, even when they overlap or the video has no visual cues to separate them.
-
Per-Speaker Voice Assignment — Assign any AI voice or cloned voice to each detected speaker individually. Mix voice types — Speaker 1 gets Premium Neural, Speaker 2 gets Studio HD.
-
Per-Speaker Subtitle Styling — Color-code subtitles by speaker. Viewers always know who's talking — critical for interviews, debates, and multi-host content.
Subtitles That Look as Good as They Read
Auto-generate precise, perfectly timed subtitles from any language. Then customize everything — font, size, position, color. Drag them anywhere on your video canvas. Export as burned-in or as an SRT file.
-
Drag-and-Drop Positioning — Drag your subtitle block anywhere on the preview canvas. Top, bottom, side — wherever it looks best for your content layout.
-
Custom Fonts & Styling — Choose from multiple font families, adjust size, weight, and color. Add shadow or background for legibility over any video background.
-
Burn-In or SRT Export — Permanently bake subtitles into the video file, or export a clean .SRT file for YouTube, Vimeo, or any video platform that accepts sidecar captions.
A Full Editor. Built Into Every Project.
No more roundtripping to Premiere or DaVinci. Trim your timeline, adjust dubbed audio segments, control volume levels per track, and preview your final output in real-time — all without leaving the platform.
-
Timeline Trim & Segment Control — Drag handles to trim any video segment. Split clips. Adjust individual dubbed audio blocks on a multi-track timeline.
-
Per-Track Volume Controls — Independently adjust the volume of the original audio, the dubbed audio track, and background music. Mix like a pro without any DAW experience.
-
Real-Time Preview — Play back any section instantly to hear exactly how the dubbed audio sits against the original video — before rendering the final export.
