What the service provides
IsThisImage reviews images you submit and returns a probabilistic assessment of whether they show signs of AI generation. Results are delivered online; the service does not create or edit images. One successful check of an image counts as one completed detection.
Eligibility and authorized images
You are responsible for submitting images you have the right to process and for using results lawfully. Purchasing users must meet applicable age and payment eligibility requirements. If you access an account, keep your login access secure and contact support about suspected unauthorized use.
How to interpret detection results
No image classifier is perfectly accurate. Scores and source indications are informational estimates, not verified proof of authenticity, ownership, authorship, misconduct or criminal activity. Edited, compressed or unusual images may affect results. Use original sources and other independent evidence for consequential decisions.
Responsible use
Do not upload content you are not authorized to submit, interfere with the site, bypass reasonable usage or payment controls, or use detection results to harass, defraud or unlawfully expose other people. See our Acceptable Use Policy for more details.
Free and paid checks
50 checks for $1.99 · 250 for $4.99 · 1,500 + lifetime API access for $14.99. One-time payment. Credits never expire. Each successful API check uses one paid credit. Daily free checks are web-only.
Developer API
Buy Developer once for lifetime API access. Refill with any pack. Any confirmed Developer refund removes API access from that purchase.
When purchases become available
Purchases are digital; there is no physical delivery. Credits are made available after payment is confirmed, not simply when a checkout page opens. Payment does not automatically run a detection. After checkout, return to the image checker and submit your next image. If credited checks are missing or a confirmed check fails, contact support@isthisimageai.org with your order reference.
Availability and changes
Results are estimates, not proof of authenticity. One-time payment. Credits never expire.
Disputes and contact
For usage, payments, account issues or service questions, email support@isthisimageai.org. The Refund & Digital Delivery Policy explains how billing errors and failed checks are reviewed. Nothing in these terms removes rights that cannot be excluded under applicable law.
Detection results can be wrong. For important decisions, verify the original source and other evidence.
