More than 500,000 professional translators, editors, and proofreaders are registered on the platform, enabling users to seamlessly blend AI translation with human review to produce high-quality multilingual content. It supports 280+ languages, and its AI Agents System covers image translation, audio translation, AI voiceover with voice cloning, and embedded video subtitles from a single platform.
Main Features
AI Agents System Across 280+ Languages
The AI Agents System can simultaneously create, translate, and localize content across 280+ languages while maintaining brand consistency. It integrates Image Translator, audio translation, AI voiceover with voice cloning, and embedded video subtitles, all with automatic layout handling.
eLearning Multi-Agent Systems and the Content Update Coworker
A multi-agent workflow translates entire SCORM packages — interactions, multimedia, and attachments included — letting enterprise L&D teams ship multilingual training up to 10x faster than traditional workflows. The Content Update Coworker, added in July 2026, watches source material for changes, finds every affected course and document in every language, and re-translates only what moved. It drafts before-and-after comparisons for human review and publishes approved changes to the LMS with versioning, audit trails, and rollback.
500,000+ Translator Marketplace
AI-based translator sourcing instantly matches projects to the best linguists by specialty, language pair, and deadline. Marketplace access is included in every plan, and project management plus payments are handled entirely within the platform. Usage is billed either pay-as-you-go or via prepayment.
Eight MT Engines
The platform's AI translation picks the best result from eight advanced MT engines and claims up to 95% accuracy on the first pass. Translation memory, glossaries, and quality checks round out the offering, combining high-volume throughput with a human touch.
