GPT Translator covers the full range of translation jobs: pasted text, uploaded documents, images, subtitles and whole web pages. More than 30 file formats are accepted, including DOCX, PDF, PPTX, XLSX, CSV, HTML, XML and Markdown, and the platform's selling point is that headings, tables, colours and layout carry over automatically so only the language changes. Output can be downloaded in the original format.
Quality controls go beyond a language picker. You can set the subject domain, tone, writing style, attach a glossary, or supply a custom prompt, which helps when the text is legal, medical or technical. Handwritten text and image translation are supported, and a phonetic or transliteration option covers scripts where a reading aid matters. A side-by-side review step lets you compare the translation with the source before downloading.
The company also ships Tranvox, a real-time speech translation layer for Zoom, Google Meet and Microsoft Teams that advertises roughly two-second latency and 50+ languages, plus an enterprise offering that blends human and AI translation, app and website localisation services, and a REST API that lets developers choose between GPT-4, Gemini, Claude and other models. On privacy, the vendor states that content is not stored beyond the translation session.
