LanguageTool is an Open Source proofreading software for English, French, German, Polish, and more than 20 other languages. It finds many errors that a simple spell checker cannot detect. It will detect the errors only when text fields are available. In this step by step guide I will show you how to install LanguageTool on your Synology NAS using Docker.

Note: This guide works perfectly with the latest version of LanguageTool v6.4

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it languagetool. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Download the .zip grammatical data from the blue link below, then choose your language. I have chosen the English .zip file which is more than 8GB.
