Chinese Text Analyser is supported on Ubuntu 14 and later, however it should work on any system that has Qt >= 5.2 and glibc >= 2.19 installed. Windows and macOS versions are also available.

You can download the latest version here.

If you are upgrading from a previous install, it is safe to reinstall over the previous version. All your configuration settings and vocabulary will be preserved.

Installation and basic functionality has been tested on recent 32- and 64-bit versions of

  • Fedora
  • Linux Mint, and
  • openSuse

using a variety of desktop and window managers.

Before installing Chinese Text Analyser we recommend that you download and install Google’s Noto Sans CJK fonts.

On Debian-based systems you do this with the following command:

sudo apt-get install -y fonts-noto-cjk

There are similar packages available for other distributions also.


Once downloaded, open up a terminal window and run the install script.

sudo ./

By default Chinese Text Analyser is installed to /opt/ChineseTextAnalyser, so you will need to run the script using sudo.

You can change this install location by using the --install-path parameter of the script, and if you are installing it to a directory that you have write permissions for then you do not need to run it with sudo.

./ --install-path ~/cta
