## Overview

Rozetta positions itself as a professional AI company rather than a generic translation tool. The core promise is "fully automated translation" — quality high enough that human review and post-editing are not required, which the company measures as a 0.003% correction rate. Its MetaRozetta brand (the successor to the well-known T-4OO industrial translation product) covers document translation, real-time speech transcription and translation, and an API so enterprises can embed translation directly into internal systems.

What differentiates Rozetta is domain depth. The platform claims coverage spanning roughly 2,000 specialized fields across medicine and chemistry, IT and engineering, business and legal, and the humanities, drawing on terminology databases and industry literature accumulated over years of professional translation work. Separate products apply the same specialization to pharmaceutical document consistency checks, financial analysis grounded in company-report data co-developed with Toyo Keizai, and localization that preserves character tone and emotion for games and media.

Rozetta is a core operating company within the Tokyo Stock Exchange Growth-listed Metareal group (ticker 6182), which means financial and governance information is publicly disclosed. It holds ISO/IEC 27001 (ISMS) certification and reports adoption by more than 6,000 companies. Pricing is quote-based and arranged through a consultation, so exact figures are only available on request.

## Pricing & Plans

Custom / quote-based pricing. Rozetta does not publish standard public plans; prospective customers request documentation or arrange a consultation and demo, and free trials are offered for individual products such as MetaRozetta document and speech translation.

## Primary Use Cases

- **Automated consistency checks on regulatory documents (Pharmaceutical and life-science teams):** Review huge volumes of regulatory submissions and papers for terminology and content consistency using a pharma-specialized document AI.

## Strengths

- Deep specialization across thousands of narrow technical fields rather than one general model
