Which one is for you

- 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 Grammarly if
- Fits if you write in lots of places and want the same checks in each
- Works for people writing English as a second language, and students who want citation and plagiarism checks in one place
Look elsewhere if
- Skip it if a spell checker is all you need, as your browser has one
- Pricey if you pay month to month: $30, against $12 on yearly billing
- Not for you if you write in a language outside its main six, which only get spelling and basic grammar
- Tight if you lean on AI for free, with 100 prompts a month and no full-sentence rewrites or tone changes
- Watch out: Pro stops at 149 seats, Enterprise has no public price, and reviewers say it flags correct text and nags you to upgrade
How we grade them
| 3.0GPAGrammarCheck.netVery good | 3.0GPAGrammarlyVery good | |
|---|---|---|
| Value for money | A$0 for the whole editor, with no paid plans. | C$12 a member a month on yearly billing is the top of this category's normal range, where the dearer quarter starts at $12.00. Pay month to month and it's $30, nearly four times the $8.33 middle. LanguageTool, on its own list of rivals, asks less. |
| Free plan and trial | AThe online editor, Free Check and Deep Check are free, with no paid plans listed. | BFree lasts as long as you like, and the checking isn't capped: spelling, grammar and tone detection on everything you write. Rewrites are Pro only, AI stops at 100 prompts a month, and reviewers say it nags you to upgrade. |
| 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. | BSpelling, grammar and tone everywhere you type, full-sentence rewrites, AI drafting, plagiarism and AI-text checks, Docs with agents that find citations and guess reader reactions, and team style guides. Advanced suggestions only cover six languages, and Docs is English only. |
| Ease of use | BNo rating on record, but paste text into a web page with nothing to set up. | B4.66 on the App Store from 225,387 ratings. That's a B, not an A, because an A wants 4.7, and 4.66 is 4.66. There's nothing to learn, mind: install it, type as normal, click what it underlines. |
| Platforms and integrations | CWeb only, with no extension, app or add-in listed. | AWindows, Mac, four browsers, iPhone, iPad and Android, so every device type, and it works inside Gmail, Google Docs, Word, Outlook, Slack, Salesforce, Zendesk and Jira. No Linux app is listed. |
| Best for | a quick no-cost grammar check in the browser | checking your writing in every app |

More comparisons
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.
