Sync – Lip sync and dub videos with multilingual precision.

Sync is an AI-powered tool that enables creators to seamlessly lip sync and dub video content into multiple languages. It is designed for professionals and creators who need to localize video dialogue while preserving the natural flow and emotional impact of the original performance.

The platform is particularly useful for marketing and content creation, allowing teams to produce ads and videos for global audiences. It fits well within the broader ecosystem of video and audio media tools that enhance production workflows.

What is Sync?

Sync is an AI tool designed for video content editing through advanced lip sync capabilities. It allows users to lip sync any video without requiring prior training on the speaker, making it accessible for quick edits and localization projects.

Tailored for content creators, marketers, and film professionals, the tool ensures that translated or altered dialogue maintains a natural flow. It is part of a growing category of AI-powered video editing solutions that streamline post-production.

Key Features

Use Cases

Underlying AI Models or Technology

Sync leverages its proprietary Lipsync-2 model, which uses machine learning to analyze and replicate a speaker's unique lip movements and facial expressions. This technology combines computer vision and speech processing to generate realistic synchronization without needing prior training data for each individual.

For dubbing and voice cloning, the tool integrates text-to-speech and speech synthesis models to create natural-sounding audio in multiple languages. The underlying AI handles the complex task of mapping phonemes to visemes (visual speech units) to ensure the lip movements match the new audio track accurately.

Pricing

Sync operates on a subscription model with usage-based pricing. Plans are tiered to accommodate different user needs, from individual hobbyists to large teams and enterprises.

The Hobbyist plan starts at $5 per month plus $3 per minute of processed video, suitable for small projects. The Creator plan ($19/month + $3/min) removes watermarks and allows longer videos. The Growth plan ($49/month + $2.85/min) is designed for teams, while the Scale plan ($249/month + $2.40/min) caters to high-volume production needs with dedicated support.
