01

Compare AI Models

Run the same sample through different AI models and compare wording, tone, and terminology.

02

Check target language

Select the target language and check whether the translation reads naturally.

03

Compare Layout

Compare headings, tables, images, and spacing with the original document.

Compare Before Uploading

  • Start with public examples rather than your own documents.
  • Compare languages and models in the same demo.

Demo FAQ

Frequently Asked Questions about PDF Demos

What should be checked when translating scanned PDFs?

Check identified text, reading order, punctuation, and text around images. Blurry or low-contrast scans may reduce accuracy.

Why does the translated PDF page display differently from the source file?

Translated text may be longer, and the original font may not be available. This may change line breaks, spacing, and page balance.

Why use the same document to compare AI models?

Using the same source makes it easier to identify differences in wording, tone, terminology, and layout.

What can international teams learn from this demo?

Teams can compare readability, model results, and layout before launching larger-scale multilingual projects.

Do I need to upload my own document to use this demo?

No. Start with sample documents and upload your own files when you're ready.

Is the preview generated from real document translation?

Yes. The demonstration will translate the selected examples and display the original preview and translation preview.

Why are there differences in results across different documents?

Document structure, scan quality, fonts, text length, and terminology may change translation and typesetting.

Can I choose another language or translation model?

Yes. Select an example, then choose a target language and an available model.

How to translate my own documents?
