Mantra develops manga-focused AI translation technology and offers Mantra Engine, a cloud translation tool for manga and vertical-scroll comics that completes all manga-translation work in the browser. The company says Mantra Engine uses integrated image-recognition and LLM-based translation to preserve character voice and contextual consistency, cutting traditional translation workflows to less than half the time. Mantra reports monthly usage of about 100,000 pages (roughly 500 tankōbon volumes) by domestic and international publishers, translation houses, and distributors. The team has published in top AI venues (AAAI) and received awards such as the AAMT Nagao Prize, reflecting academic validation of its approach. Mantra also operates the Langaku English extensive-reading app and plans to commercialize its technology into novels, games, and video content. The company intends to use new funding to accelerate R&D and improve translation accuracy toward a five-year goal of consumer-grade reading quality, while advancing global expansion.
