Senior User of a Popular Forum

The original book's formatting has been faithfully reproduced, which gives it an advantage over Immersive Translation. The multilingual support is also quite good. Although the source language was specified as English, the German content in the document was also correctly translated.

Chenxi

Researcher

Translating academic papers is often an unavoidable challenge for researchers. Traditional translation tools usually struggle with specialized terminology and complex sentence structures. Since I began using Doclingo, I have not only solved the accuracy issue but also significantly improved translation efficiency.

JC.L

Senior Designer, Foreign Trade Company

Our company frequently deals with PDF design drawings. While the translation volume is not large, we require high-quality PDF translation and text recognition. After trying many translation tools, I found that Doclingo offers the best PDF translation capabilities.

If you need text translation, I highly recommend trying this tool. Most translation tools don’t handle texts within images well, but Doclingo preserves the original document formatting better than any AI translator I’ve seen. It supports most mainstream document formats and also allows batch translation and online editing.

Mark Jiang

Master's student

During my graduate studies, this tool has been an invaluable assistant, helping me read a large number of English research papers quickly and saving me from many detours on my academic journey. I highly recommend it to fellow students struggling with English papers—you’ll love it once you try it!

Everyday Moments

An incredibly useful PDF translation tool! As a free alternative to many translation softwares, it supports multiple file formats, including PDF, PPTX, and DOCX.

Ume-Chan Japanese

Language Blogger, Japanese Translator

As a Japanese translator and language blogger, I often come across high-quality materials and professional translation projects that contain difficult sentences and specialized terminology. Sometimes, tight deadlines make it hard to keep up with the translation speed, and the results are less than ideal. After discovering Doclingo, everything became so much easier! It not only integrates major AI engines but also excels at preserving the original formatting.
