Real, or made by AI?
Check an image, video, document or assignment for hard evidence of AI generation — the hidden metadata, file history and copy-paste leftovers that AI tools leave behind.

Evidence found
Honest limits: metadata is proof when present, but it is easily removed. Screenshots, WhatsApp, Instagram, TikTok and most platforms strip or re-encode it — so “no evidence” never means “not AI”, and camera metadata can in principle be forged. Invisible watermarks such as Google’s SynthID cannot be read by any browser tool. Treat this as one signal, not a final judgment. Files carrying C2PA credentials can be independently verified at contentcredentials.org/verify.

Document report
Direct evidence — AI leftovers & document history
Writing-style indicators — weak signals, never proof on their own
Honest limits: no tool — this one or any commercial detector — can prove text was written by AI from its wording alone. OpenAI withdrew its own AI-text classifier for low accuracy, and research shows detectors wrongly flag non-native English writers far more often. That is why this page gives no percentage score: it separates hard evidence from weak style signals. Never penalise anyone on style indicators alone. The most reliable check is the author’s version history (Google Docs or Word/OneDrive) plus a short conversation about the work. Your text stays on this device; for PDFs only the open-source PDF reader library is downloaded.
01 · Proof
Hard evidence
AI-tool signatures, Content Credentials (C2PA), chatbot leftovers and AI-search links. When present, these are proof.
02 · History
File history
Camera data, editing time, edit sessions and the software that produced the file — strong signals, never a verdict on their own.
03 · Honesty
Honest limits
No percentage scores. Stripped files are reported as inconclusive, and writing style is shown as a weak signal only.
