How we grade them
| 3.0GPAGrammarlyVery good | 2.6GPAPangramGood | |
|---|---|---|
| Value for money | 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. | CGraded against its own alternatives, as it checks text rather than helping you write it. Individual is $15 a month billed yearly ($20 monthly) for 300,000 words, above Grammarly's and Paperpal's $12 and nearly twice QuillBot's $8.33, which all do more besides. |
| Free plan and trial | BFree lasts as long as you like, and the checking isn't capped: spelling, grammar and tone detection on everything you write. It's a plan you could genuinely live on. Rewrites are Pro only, AI stops at 100 prompts a month, and reviewers say it nags you to upgrade. | BFree for good with no payment method: 20 credits a day, about 2,000 words, plus 3 image scans, and it resets daily. One person checking the odd essay or article could live on that. A teacher marking a whole class in an evening couldn't. |
| Features | 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 style guides for a team. The job covered, bar one named gap: the clever suggestions only cover six languages. | CIt does AI detection fully: scores and marked passages across 20+ languages, image checks, similarity checks, OCR for scanned files and feed scanning. But it's a much smaller job than a writing tool's, as it only tells you who wrote the text. |
| Ease of use | 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. | BNo store rating on record, but there's nothing to set up: paste the text or upload a file, and the result comes back with the suspect passages marked. |
| Platforms and integrations | 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. | BWeb and a Chrome extension, with Google Docs and Gmail on paid plans, Canvas, Moodle, Google Classroom and Brightspace for schools, and an API. No desktop or phone app. |
| Best for | checking your writing in every app | checking whether text was written by AI |
