Which one is for you
Pick GrammarCheck.net if
- Fits if you want a quick check of a paragraph at no cost
- Works for occasional writers who don't want an account
Look elsewhere if
- Skip it if you write in Word or Docs, because no add-in or extension is listed
- Not for you if your text is private, since the disclaimer says text may go to a third-party API provider
- Too light for fine editing, as the site says automated checks may miss errors
- Watch out: the site may earn commissions on third-party installs it points to
Pick LanguageTool if
- Fits if you write in several languages and not only English
- Works for people who write in LibreOffice, Thunderbird or Apple Pages and want a checker inside them
Look elsewhere if
- Pricey if you pay monthly, at $24.90 against $69.90 for the whole year
- Tight if you're staying free, as it checks 2,000 characters per text field and allows 3 AI rephrasings a day
- Watch out: there's no Premium trial, only a 14-day money-back guarantee, and Teams is sold from 2 users
- Skip it if you want an app on an Android phone, as none appears on the site
- Too light for plagiarism checks, AI-text checks or summarising, which some rivals include
How we grade them
| 3.0GPAGrammarCheck.netVery good | 2.8GPALanguageToolGood | |
|---|---|---|
| Value for money | A$0 for the whole editor, with no paid plans. | BPremium is $69.90 billed annually, about $5.83 a month, dropping to $4.99 a month if you commit to two years, which is inside this category's cheaper quarter at $5.00. Pay by the month and it's $24.90, more than four times the annual rate, so don't. |
| Free plan and trial | AThe online editor, Free Check and Deep Check are free, with no paid plans listed. | CBasic is free for as long as you like and checks grammar, punctuation and spelling across 30-plus languages. But it stops at 2,000 characters per text field, which any real document walks past, Picky Mode is limited and AI rephrasing is 3 a day. No trial of Premium either. |
| Features | CSpelling, grammar and punctuation, readability stats, a flow score and writing goals. It does that job fully, but it's a smaller one than a full assistant. | BIt covers the checking job in full: grammar, spelling, punctuation and style in 30-plus languages, 20,000 extra checks on Premium, texts to 150,000 characters, AI paraphrasing and a style guide. What it hasn't got is the extras its rivals carry, like Grammarly's plagiarism and AI-text checks or QuillBot's summarising. |
| Ease of use | BNo rating on record, but paste text into a web page with nothing to set up. | BNo store rating on record, but there's nothing to set up: add it to your browser, Word, Google Docs or mail client, or install the app, and it underlines things where you already type. Hosting your own server is an option, not a requirement. |
| Platforms and integrations | CWeb only, with no extension, app or add-in listed. | BAdd-ons for Chrome, Edge, Firefox, Safari and Opera, plugins for Google Docs, Word, Apple Pages and LibreOffice, email add-ons, apps for Windows, macOS and iOS, and a proofreading API. The hole is Android: no app for it appears on the site, so no A. |
| Best for | a quick no-cost grammar check in the browser | grammar checking in more than one language |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
