  • PyLanguagetool - Capturing an output from command line
    I'm using pylanguagetool, a Python wrapper for LanguageTool, a spelling/grammar correction application. It operates in both Python and in Windows command line. It is particularly useful in command line, as it displays outputs in the following manner. I'd like to capture this output, preferably in the same format. However, the standard methods of capturing command line outputs appear to generate encoding errors. For example,

    It looks like it's using LanguageTool in the background (which you can use without all the ads --, and it seems to do okay for spelling, but it's certainly not going to be all that helpful for grammar. For example, if you plug an excerpt from the following humorous poem (which is intentionally written with multiple major grammatical errors), it will not find any errors at all:

  • Alternatives to Grammarly for formal articles | 2021-06-01
    I use LanguageTool and I like it. Regarding your specific case, the other day it suggested that I use either "little" or "bit" instead of "little bit" so it seems conciseness checks are there. I don't think it has IDE integration, not sure about Overleaf. I just use the free version, supposedly the paid version detects a lot more issues, but I can't vouch for it.

    Hi, it was not that bad, just use open source grammar checking tool and it’ll help you immensely. Their premium is also worth it.

    If you do want software, I'd also highly suggest LanguageTool! While I have not looked into the terms of their cloud offering, their software is FOSS, so you can totally just run a local copy of the server and get all the benefits! I really like this VSCode plugin which will spin up a server and check latex and markdown documents.
