I like LanguageTool, but often I write text in programs without LanguageTool support. That's why I wrote a CLI to quickly check text against the new JSON API:
It supports text from a file, the system clipboard or another program via pipe and can be configured via command-line parameters or a config file.
If you want to try it out yourself, a simple
pip install pylanguagetool should be enough.
If it isn't working or you have ideas for improvement, open a Github issue or message me.
I hope you like it.
