Which one is for you
Pick GPTZero if
- Fits if you grade or review writing and want to check it for AI
- Works for teachers whose classes run on Canvas or Google Classroom
Look elsewhere if
- Tight if you check a lot: the free plan stops at 10,000 words a month
- Skip it if you want one clear price, because paid prices vary by region and by test
- Pricey if you want a team: two-seat minimum, and the API is priced separately
- Watch out: the vendor's own wording suggests a detector is a guide, not proof
Pick Pangram if
- Fits if you're a teacher checking whether an essay was written by the student
- Works for editors screening submitted articles before they run
Look elsewhere if
- Skip it if you want help writing, as it only checks what's already written
- Tight if you mark a whole class on the free plan, at about 2,000 words and 3 image scans a day
- Pricey if you scan in bulk through the API, at $0.05 per 100 words once Individual's $10 of monthly API credit runs out
- Watch out: refunds are for individual plans only, within 14 days and with fewer than 20 credits used
- Watch out: Team starts at 2 seats, Professional is billed at sign-up, and zero data retention needs sales-priced Enterprise
How we grade them
| 2.4GPAGPTZeroFair | 2.6GPAPangramGood | |
|---|---|---|
| Value for money | CNo single US dollar list price could be read, and prices vary by region. Left in the middle of the category. | 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 | CA free plan up to 10,000 words a month, which a regular user will hit. | 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 | BAI detection, writing replay, plagiarism, grammar feedback, a hallucination checker and an API. Nothing in the listing shows a gap in the core job. | CIt does AI detection fully: scores and marked passages across 20+ languages, image and video 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 | CNo store rating on record. You make an account and connect it to Docs or a class system. | 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 | BWeb and a Chrome extension, with Google Docs, Canvas, Google Classroom, Gmail and an API. | 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 whether text looks AI-written | checking whether text was written by AI |

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.
