Real DubSync output — switch languages to compare
Our Mission — Content Without Language Barriers
DubSync is developed in partnership with NGO «Institute of Ukrainian-Iberoamerican Relations», a non-profit organization working to break down language barriers in international communication.
Every year, millions of people can't access quality educational content because of language barriers. We're changing that — developing localization technologies, supporting creators and educators, and building content accessibility programs.
Our goal: a world where knowledge and culture are available to everyone, regardless of language.

How DubSync works
DubSync uses AI to automate the entire video dubbing workflow — from transcription to voice cloning to lip sync — in three simple steps.
Step 1
Upload your video
Upload any video file (MP4, MOV, AVI up to 2GB). DubSync automatically transcribes the original audio and detects the source language.
Step 2
AI processes your video
Our AI translates the transcript, clones the speaker’s voice in the target language, and generates lip-synced audio that matches mouth movements. The entire process takes 2–5 minutes for a typical 10-minute video.
Step 3
Download your dubbed video
Review the result, make any edits to the translation, and download your dubbed video in up to 4K quality. Share it with your global audience instantly.

Same voice, new audienceLoved by creators
What creators, educators, and teams say about DubSync.
“DubSync doubled my international audience in two months. The voice cloning is so good that my Spanish viewers genuinely think I speak Spanish. Game changer for any creator going global.”
“I run a cooking channel and needed my recipes in Japanese and Korean. DubSync nailed the tone — warm and conversational, not robotic. My Asian audience grew 400% in 3 months.”
“As a solo developer, I integrated DubSync's API into our LMS in one afternoon. Now every course we publish automatically gets dubbed into 6 languages. The documentation is clear and the API is rock solid.”
“I was skeptical about AI dubbing until I tried DubSync. The voice cloning captured my energy and enthusiasm perfectly. My French and German versions sound like me, not a text-to-speech bot.”
“We localize corporate training videos for 12 countries. Before DubSync it took 3 weeks per language. Now it's done in a day. The quality is consistent and our compliance team approved it.”
“DubSync helped me turn my English fitness tutorials into a Spanish-language brand. The lip sync makes it look completely natural. My Latino audience engagement is through the roof.”
