Use AI to translate PDF files in your knowledge base, producing translated and bilingual side-by-side PDF versions
MaiAgent provides AI-powered PDF document translation, allowing you to translate PDF files in your knowledge base into a specified language. After translation, two versions are produced:
Translated version: Contains only the translated content in the target language
Bilingual side-by-side version: Displays the original text and translation side by side for easy comparison
Supported languages include: Traditional Chinese, Simplified Chinese, English, Japanese, Korean, Spanish, French, German, Portuguese, Russian, Arabic, Italian, Dutch, Polish, and Turkish.
Currently, only PDF format is supported for document translation, and the PDF must contain extractable text content (scanned/image-only PDFs are not supported).
In the Documents tab of your knowledge base, click the PDF file you want to translate to open the document details page.
Click the Translate PDF button in the upper right corner. If the file already has a translation record, the translation results dialog will appear first — click Translate Again to open the settings. For first-time translations, the translation settings dialog opens directly.
Source Language
The language of the original text. Defaults to "Auto Detect" — the system identifies it automatically
Target Language
The target language for translation (required)
Large Language Model
Select the LLM model to use for translation
Custom Terminology/Prompt
(Optional) Guide the translation style or specify terminology mappings, e.g., "Translate 'Hermione' as 'Miao-Li'"
The custom prompt supports up to 5,000 characters and is ideal for specifying proper nouns, brand names, or particular translation styles.
Click Confirm to start the translation task in the background. The status updates in real time during translation, and results are displayed automatically upon completion.
After translation is complete, click the Translate PDF button to open the translation results dialog, which contains three tabs:
Preview the bilingual side-by-side PDF with the original text and translation displayed side by side.
Three file download options are available:
Original file: Download the untranslated original PDF
Translated version: A PDF containing only the target language translation
Bilingual side-by-side version: A PDF with the original text and translation displayed side by side
View complete statistics for the translation task:
Translation configuration: Source/target languages, LLM model used
Processing statistics: Token consumption, number of LLM calls, processing time breakdown
File information: File size and character count for both the original and translated files
Timestamps: Creation, start, and completion times along with the final status
A single PDF file can be translated multiple times (e.g., into different languages or using different models), and each translation is saved as a separate version.
Use the Select Translation Version dropdown at the top of the translation results dialog to switch between versions. The version format is: Date | Source Language → Target Language | Model Used.
To translate again, click the Translate Again button to open a new translation settings dialog.
