AI Document Translation: 99 Languages Without a Human Translator
FlipFiles Pro · June 2026 · 8 min read
Professional document translation has always been expensive and slow. A human translator charges $0.10-0.25 per word — translating a 5,000 word legal document costs $500-1,250 and takes days. For many businesses, this price point makes translation impractical for anything other than critical documents. AI translation at FlipFiles Pro changes this equation completely.
What Is NLLB-200?
NLLB-200 (No Language Left Behind) is Meta AI's multilingual translation model released in 2022. It was trained on text in 200 languages, with a focus on including lower-resource languages that previous translation systems ignored. The model achieved state-of-the-art results across 200 language directions in independent benchmarks.
FlipFiles Pro uses the distilled 600M parameter version — optimised for fast server inference while maintaining high translation quality across all supported languages.

Key Use Cases
Business Documents and Contracts
Companies operating internationally regularly need to translate internal policies, supplier contracts, and employee handbooks. AI translation provides a high-quality first draft that a bilingual employee or professional translator can review and refine — at a fraction of the cost of full professional translation.
Technical Documentation
Product manuals, API documentation, and technical guides need translation for international markets. NLLB-200 was trained on technical text and handles technical vocabulary more consistently than general-purpose translation tools.
Multilingual Customer Communications
Support responses, onboarding emails, and help centre articles translated into customers' native languages significantly improve comprehension and satisfaction scores.
Video Language Dubbing
The translation pipeline extends to video. FlipFiles Pro's Video Language Dubbing tool transcribes a video with Whisper, translates the transcript with NLLB-200, converts the translated text to speech using gTTS, and combines the new audio with the original video. This creates a complete dubbed video in the target language — in minutes rather than the days or weeks professional dubbing requires.
