According to the LanguageTool, this is just the name of the open-source grammar checking tool created by a group of language enthusiasts and application engineers.

This tool is mainly used for Grammarly alternatives, but as I said, there are no other tools like Grammarly. Still, if you use Grammarly and want to try another one, LanguageTool can be the next solution for you to check your grammar mistakes.

Why Should You Use LanguageTool?

This one is also great and perfect for getting started with a grammar checking tool, but did you know this tool’s most popular side?

Its price range, what a price range they offer! Just perfect for beginners who don’t have enough $$$ to get a premium grammar checking tool and who just started writing.

Like others on the market, Ginger provides a series of advanced and additional options, including a sentence rephrase, text reader, dictionary, a dedicated trainer, and a translator over 50+ languages to grow your English writing skills.

But despite having so much, if there were plagiarism checking tools in their plan, it’ll be better! There is no plagiarism checking tool, and I think this is one of the tool’s bedsides.

Plans & Pricing:

Like others on the Best Grammar Checker Tools list, this one also has two versions, free and pro.

The free plan is just like a limited using capacity, so you’ll only get some basic grammar checking features that always come with other tools.

Your monthly basisGinger’snow if you’re going to use the tool because it may limit the number of grammar corrections you’re entitled in a particular period like up to 50 errors corrections/m.

In Ginger’s premium plan, we can see that pricing is expensive if you buy their plan every month. But on the other hand,

if you’re a little bit clever, you may want to buy the plan yearly-based because usually, the monthly plan costs around $20.97 per month, but if you buy the plan for a year, you have to spend only $7.49 per month, which will stand at $89.88 in one year!

And if you buy the plan for three years and for the first time, the plan’s price is $3.47 per month, which will stand at $124.95 in three years!

WhiteSmoke is also coming with a plagiarism checker, grammar checker, one-click install proofreading, and translator tool that support all writing platforms.

In a word, it will be the complete integrated content writing solution for both platforms Mac and Windows.

Business Plan: I think the price range of this plan should be under $11 per month, and this is why I will only suggest you buy the plan if you’re a professional editor or working in a kind of place where you need to write more and more. Otherwise, this plan might waste your $$,

Anyway, the plan will cost $11.50/m, which will stand at $137.95 for yearly-based payment.
