How to Use Doclingo’s Text Selection Features

Doclingo's Text Selection feature allows you to select text in your translated PDF document and interact with AI to get explanations, insights, translations, or copy text instantly.
This feature supports both text-based and scanned PDF documents and is currently available on desktop browsers only.


1. Open Your Translated Document

After completing your document translation, go to Personal Center → Usage Records.
Find your translated PDF document and click “View” to open the document preview.


2. Select Text in Your Document

  1. Use your mouse to highlight the text you want to interact with.
  2. A floating toolbar will automatically appear with the available Text Selection options.



3. Choose a Text Selection Feature

After selecting text, choose an action from the floating toolbar:

  • Chat: Ask AI questions about the selected text.
  • Explain: Get detailed explanations of complex sentences or technical terms.
  • Insight: Generate key insights or a quick analysis.
  • Translate: Translate the selected text into another language.
  • Copy: Copy the selected text instantly.
