Understand an image or writing check
Choose the question you are trying to answer. These guides explain the clues our tools can use, when a result may be uncertain, and what other evidence to seek.
Images and deepfakes
Start with the original file when possible. Learn how AI generation, small edits, compression, and missing provenance affect the strength of a result.
Writing
AI writing detectors look for patterns, not the identity or intent of a writer. Explore fair use of a result, especially for essays and other consequential work.
Evidence and research
Creation records and ordinary metadata answer different questions. Read our research protocol before interpreting any accuracy claim.
