Question 1

Is the AI document translator free to use?

Accepted Answer

Yes. New users get free credits each month — enough to translate several documents. Heavy users can buy credit packs or subscribe to a monthly plan starting at $9/month.

Question 2

Which file formats are supported?

Accepted Answer

PDF (text-based and scanned), Word (.docx), PowerPoint (.pptx), Excel (.xlsx), plain text and Markdown. Output is in the same format as the input.

Question 3

How long does it take to translate a document?

Accepted Answer

Most documents under 50 pages translate in 1–3 minutes. Larger files (500+ pages) usually finish within 10 minutes. We email you when long jobs are ready.

Question 4

Will my formatting be preserved?

Accepted Answer

Yes. We rebuild the document using the original layout — headings, columns, tables, embedded images, footnotes and slide animations all stay in place.

Question 5

Which languages can you translate between?

Accepted Answer

We support 100+ languages including all major European, East Asian, South Asian and Middle Eastern languages. Auto-detect identifies the source language.

Question 6

Do you handle scanned PDFs and images?

Accepted Answer

Yes. We run OCR on scanned PDFs and image-based pages, then translate the extracted text. Output is a searchable PDF with the translated layer.

Question 7

Is my document confidential?

Accepted Answer

Files are encrypted in transit and at rest, scoped to your account, and auto-deleted after 30 days. Enterprise customers can require zero-retention or on-premises processing.

Question 8

Can I edit the translation afterwards?

Accepted Answer

Yes. After translation you can review side-by-side, edit any segment, and export the corrected version. Changes can also be saved as a custom glossary for future jobs.

Question 9

Do you support glossary or brand terminology?

Accepted Answer

Pro and Team plans support custom glossaries — upload a CSV of preferred terms and the model will apply them consistently across documents.

Question 10

How does UniAI compare to Google Translate or DeepL?

Accepted Answer

UniAI uses a mix of frontier models (GPT-4o, Claude 3.7, Gemini 2.5) with layout-aware document parsing. Quality matches DeepL on European languages and exceeds Google Translate on long-form business and technical documents.
