Upload your PDF and wait for processing, then choose a translation filter in the reader. Work through the chapters without repeatedly copying text between tools.
Keep the source beside the translation when a definition, formula, or technical term needs a closer look. Compare the wording before using it in your own notes.
AI translations can miss nuance, and PDF text extraction can introduce errors. Check consequential details against the source, especially in scanned or complex documents.
This feature provides a translated reading view inside Redia. The demonstration shows reading and comparison, not an exported PDF with the original layout.
Yes. Original text comparison lets you inspect the source alongside the reading version, so you can check the wording of a passage.
