mathtranslate 3.0.2

Translate math-heavy papers

MathTranslate

English | 简体中文

GUI download address

This is a project to provide translation of scientific papers with heavy math symbols from any language to any language while keeping the math symbols unchanged. In most translation softwares you wouldn't be able to keep equations and it would annoy you.

The main work of this project is to translate LaTeX files based on Google Translate in plain text, and finally realize the translation of pdf.

Here's an example of what you get finally.

Backend engine

The default engine is google translate, which can not be accessed with IP in mainland China. For users with IP in mainland China we provide the tencent engine, although its accuracy is not as good as the google engine. To use the tencent engine, you need to register the Tencent Translation API account. After registration, you can get the secret ID (not the APP ID!) and secret Key in Tencent Console. Tencent Translate is the translation API with the highest free quota to our knowledge besides Google Translate, with a free quota of 5 million characters per month, and no fee will be deducted if there is no manual recharge (that is, there is no need to worry about misuse).

GUI Installation (not stable now)

Simply download the corresponding executable file and you are done!

GUI usage (not stable now)

You can set the translation engine and language in the Preference page. If you plan to use the tencent engine, you need to set the secret ID and secret Key.

1. If you want to translate a paper on arxiv, you can use the Arxiv Translate function. You just need to enter the arxiv number of the paper you want to translate (for example 2205.15510). After the translation you will get a .zip file, which contains the latex source code of the arxiv project.
2. If you want to translate a paper only with pdf version, you can first convert the pdf to latex by mathpix and then use the File Translate function. Unfortunately, mathpix requires a fee after exceeding a certain amount of usage. Here is the price list. After the translation you will get a .tex file which contains the corresponding latex file.

After the translation is done you can upload either the .zip (New Project - Upload Project) or .tex (New Project - Blank Project and copy-paste) file to overleaf for online compilation. Note: you have to set the compiler to XeLatex in Menu - Compiler.

Command line installation

1. Install python3 and pip.
2. pip install --upgrade mathtranslate

Command line usage

For Windows user you may need to run cmd or powershell as administrator.

1. Prepare or generate a tex file or project. You can obtain a tex file or project in the following ways:
   • For most arxiv papers, the latex source code is public, and we provide a simple API to translate the entire project with just one click using an arxiv number.
   • Use mathpix to convert the pdf you want to translate into latex code. Mathpix can directly convert pdf or screenshot to latex code. Unfortunately, mathpix requires a fee after exceeding a certain amount of usage. Here is the price list.
2. (For Tencent Translation API users) Run translate_tex --setkey to store the API secretID and secretKey.
3. Translate the tex file or project in command line.
   • To translate a single file: translate_tex input.tex -o output.tex will generate a translated tex file output.tex.
   • To translate an arxiv project: translate_arxiv 2205.15510 will generate a translated tex project 2205.15510.zip.
4. Compile your tex file. For a single file, you can use the command xelatex output.tex from texlive. Chinese translation requires the xeCJK package. For arxiv projects, we recommend uploading the obtained .zip file to overleaf for online compilation (New Project - Upload Project). Note that you need to set the compiler to XeLatex in Menu - Compiler.
5. You can change the default settings of translation language and engine through command line arguments -engine, -from, -to. For example, translate_tex -engine tencent input.tex -o output.tex. You can also permanently change the settings through translate_tex --setdefault. You can view more details through translate_tex --help. translate_arxiv also provides exactly the same command line arguments, which have the same effect.
