Switch from Grammarly to LanguageTool
Install the LanguageTool extension, turn off Grammarly, and self-host the server if the text should not leave your network. Tone rewrites and plagiarism checks do not come along.
Time: Minutes for the browser extension. Half a day if you self-host.
Export
Step 1
Turn Grammarly off in one browser
Disable the extension without uninstalling it, so you can compare a paragraph side by side.
Step 2
Note the custom style guide
Grammarly style settings do not export. Write down words you had marked as correct or forbidden.
Step 3
Decide where text is allowed to go
The public LanguageTool service receives the text you check. Self-hosting is the private option.
Import
Step 1
Install the extension
Add LanguageTool in the browser you write in, and the office add-in if you use one. Pick the languages you actually write.
Step 2
Optional: run the server
The LGPL server is a Java process. Point the extension at your URL. Basic rules work without the large n-gram data. Suggestions get better if you add it.
Step 3
Add a personal dictionary
Load the words Grammarly had learned: product names, surnames, and the jargon it kept flagging.
What breaks
Tone and generative rewrites
LanguageTool underlines errors. It does not rewrite a paragraph in a friendlier tone the way Grammarly Pro does.
Plagiarism checks
Not part of LanguageTool. If that was the reason for the subscription, this is the wrong replacement.
Mobile keyboards
Grammarly's phone keyboard habit may not have a perfect twin. LanguageTool has mobile apps. Try them before you cancel if you write on a phone.
For a week, keep both extensions installed and only one enabled. The gaps are obvious quickly, and they are mostly tone and rewrites, not spelling.
