FAQ

What should I do if recognition is not accurate?

  1. Check whether the scanned file is clear and whether the text is blurred, tilted, or blocked by shadows.
  2. In multiple-document recognition, choose a more suitable recognition language and output option.
  3. After recognition, review numbers, proper nouns, and table content carefully.
  4. If the original scan quality is low, scan the file again before running recognition.

Which recognition languages are supported?

  1. You can set the recognition language during multiple-document recognition.
  2. Common usage scenarios include Chinese, English, Japanese, Korean, and other languages.
  3. If a document contains multiple languages, process it with the main language first and then review the result page by page.

Can I edit the file directly after recognition?

  1. Yes. After recognition, the text becomes editable.
  2. Try selecting the text first to confirm that it is no longer only image content.
  3. Then edit, copy, search, or save the document as needed.

When is multiple-document recognition useful?

  1. It is suitable for processing multiple invoices, archives, scanned contracts, or research materials at one time.
  2. Before adding files, organize file names and save locations for easier archiving later.
  3. After batch recognition is complete, review key pages file by file to confirm that the result meets your needs.
