How we grade them
| 2.6GPAPangramGood | 2.8GPAQuillBotGood | |
|---|---|---|
| Value for money | 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. | CPremium is $8.33 a month billed annually, which is exactly the middle for writing tools, and one account covers every tool on up to 10 devices. Monthly billing is another story: the iOS app lists it at $19.99. |
| Free plan and trial | 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. | CFree for good, but in small bites, and the caps are ones you'll hit: paraphrasing 125 words at a time in 2 modes, basic grammar fixes, summaries of up to 1,200 words, and limited goes on the Humanizer, AI Detector and AI chat. |
| Features | 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. | BIt covers the whole job of a rewriting and checking kit: a paraphraser with 9 modes plus custom ones of your own in 23 languages, a grammar checker, a summarizer, a translator for more than 40 languages, an AI detector, a humanizer, plagiarism checks and a citation generator. |
| Ease of use | 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. | BNo store rating on record, so we go on the listing: paste text, pick a mode, read the new version, with nothing to set up, and the extensions and keyboards put it where you already type. The free plan lets you try that before paying. |
| Platforms and integrations | 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. | AWeb, Mac and Windows apps, iPhone and Android apps and keyboards, plus Chrome, Edge and Safari extensions and a Word add-in. Every device type covered and places to plug into, which is rare in this category. Premium runs on up to 10 devices at a time. |
| Best for | checking whether text was written by AI | rewording text you've already written |
