TeXstudio has an interactive grammar checker, see: Features.

LanguageTool works standalone and checks grammar. It can be used via copy and paste, or export via latex2html or tex4ht or PDF conversion to text.

You could also use Word as grammar checker. Again, you need to get your text into Word like via latex2html or tex4ht. A simpler solution may be using the Adobe PDF reader and click in the main menu "Save as..." and choose Word / docx.

The conversion way seems to require some work, but if you do it at the end you need to do it just one time. I would take the very final version of my document and then run the spell check and grammar check with Word, or LanguageTool, or both - it's safer to run several checkers to have the highest chance that all errors are found. Once the final check is done, LaTeX can be run again and at this time the grammar would not change anymore, as in the final version there would only be last fine-tuning.

You still have to invest some manual labour. There is no magic app yet that reads your mind ;-)
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

You can have your LaTeX editor on the left side of the screen, Word on the right side. So you see the errors marked on the right side, and make the changes on the left side in your LaTeX document.

As Stefan pointed out, if you interact with Language Tool directly, you first need to remove markup from the file --which is very tedious. Plus, it's hard to track the errors back to your original source file afterwards. Of course you can reserve this step for the very end, but I still think it is sub-optimal.

To solve this problem, I've just finished writing a new tool for checking spelling and grammar directly on LaTeX files, called TeXtidote:

The program can remove markup from the file and send it to the Language Tool library, which performs a verification of both spelling and grammar in a dozen languages. What is unique to TeXtidote is that it keeps track of the relative position of words between the original and the "clean" text. This means that it can translate the messages from Language Tool back to their proper location directly in your source file. By default, TeXtidote produces an HTML report that shows your original sources, with the errors found by Language Tool highlighted at the correct location:


The tool is free and easy to install (OS-independent, requires Java). I encourage you to give it a try and tell me what you think!

I have listed some of the Free, Libre and Open Source Grammarly alternatives here in this post. I have also linked to some of the FLOSS English linters and plagiarism checkers. From which LanguageTool integrates very nicely with TeXstudio. Instructions for Windows from hereand here:

  1. install Chocolatey
  2. open PowerShell as administrator and run "choco install miktex texstudio languagetool" if they are not already installed
  3. In TeXstudio menu bar > Options > Configure TeXstudio... > Language checking >
    1. check "start LanguageTool if not running" if it is not checked
    2. set "LT path" to "C:\ProgramData\chocolatey\lib\languagetool\tools\LanguageTool-4.6\languagetool-server.jar" or search in "C:\ProgramData\chocolatey\lib\languagetool\tools" for the latest version at the time
    3. set "LT Argument" to "org.languagetool.server.HTTPServer -p 8081"
  4. in "LanguageTool options" make sure the "Run server on port ..." is checked and the port is the same as you had set before (e.g., 8081)

P.S. I tweeted about this hereand here

I still use grammar checkers when it comes to writing academic papers. I use Grammarly as I'm quite satisfied with its quality. I tried a few other spelling and grammar checkers such as Reverso Speller and Hemingway App, and both worked pretty well for me. They are slightly different, but the principle is very similar. After some time I come up with Grammarly as the grammar checker that works best for my purpose, so that's my choice for now.

I despise everything use syntax checkers with regards to composing scholarly papers. I use Grammarly as I'm very happy with its quality. I attempted a couple of other spelling and punctuation checkers, for example, Reverso Speller and Hemingway App, and both worked entirely well for me. They are marginally extraordinary, however, the standard is fundamentally the same as. After some opportunity I concoct Grammarly as the punctuation checker that works best for my motivation, so's my decision for the present.
