AI PDF translation that keeps the original layout intact
Tables, figures and diagrams stay where they were, so context and data structure survive translation and you can share the result as-is.
Pro Premium and Business plans accept a single file of up to 1,000 pages and 200 MB, so long reports and manuals do not need splitting.
Register your own glossary so product names, abbreviations and internal terminology always come out with the same wording.
Translate and download as often as you like on a flat monthly plan, and work with online files directly through the Chrome extension.
