Our verdict on T-4OO
T-4OO is Rozetta’s cloud-based AI translation platform for organizations working with specialized business and technical content. It handles legal, medical, manufacturing, chemical, patent, financial, and other professional material, with translation available for PDF, Word, Excel, and PowerPoint files while preserving layouts. Website translation is also available from a supplied URL. This focus makes it a fit for mid-market and enterprise teams translating documents and sites where terminology and formatting matter; it is less suited to buyers seeking a broadly priced self-serve tool.
Its domain controls are central to the product. Users can select from approximately 2,000 specialized subject areas, edit translations side by side in a browser, and draw on a company-specific translation database built from previously translated sentences. Terminology suggestions and bulk term replacement support consistent wording, while automatic highlighting identifies potentially incorrect translations and provides explanations and alternatives. Together, these tools address review and reuse needs in professional content workflows rather than only converting text between languages.
T-4OO is offered on the web and through an API, which can connect translation to other platforms. The vendor advertises a free trial, but there is no free plan; according to the vendor’s pricing description, paid pricing is based on translation volume and requires contacting sales. That model may suit organizations evaluating usage with a sales conversation, but it gives buyers less public pricing detail for comparison. Phone support is available, though not 24/7. Choose T-4OO when layout preservation, domain selection, and company terminology are important; consider alternatives if public tier pricing or named platform integrations are priorities.
