How text and reports are handled
An AI score is
an estimate.
AI detectors look for patterns common in AI-generated writing. They can also misclassify human writing, especially short, heavily edited, or non-native English text.
See sentence-level highlights.
Find the sentences that show stronger AI writing patterns, rather than relying only on an overall score.
Choose which reports to save.
You can check text without an account. With Plus, save a report only when you choose to keep it.
The same scoring method on every plan.
The free and paid plans use the same detection method. You pay for more room, never a different answer.
WHAT CAN YOU CHECK?

Questions about
AI detection?
Can an AI checker tell me for sure?+
No. AI detectors identify patterns, not authorship. Short, edited, or non-native English writing can be misclassified. Use results alongside your judgment and talk to the writer before acting.
Is the free checker actually free?+
The free plan includes 3 checks a day, up to 1,000 words each, with the same scoring method and sentence highlights as paid plans. No account is needed. If live detection is unavailable, you can explore a clearly labeled sample result.
What happens to the text I paste?+
Your text stays in the page until you press Check. Live checking sends it to the detection provider. Reports are stored in your account only when you choose Save report; bulk checks use temporary processing storage. See Your data for provider retention and storage details.
What does Plus include?+
Plus is designed for up to 15,000 words, PDF and Word uploads, batches of 50 files, saved reports, and history. Choose $9.99 monthly or $59.99 annually. Fair use applies.
Can I cancel or get a refund?+
The intended paid service includes cancellation through the billing portal and a no-questions refund within 7 days. Paid checkout will only be available when the payment service and operator support details are configured.
Good judgment starts with knowing the limits. DidAIWrite results are estimates and can be wrong. Never use a score alone to make a decision about someone.
