ChatGPT Detector
Paste any text and see in seconds how strongly it carries the stylistic fingerprint of ChatGPT and similar AI models — with the exact sentences highlighted and a four-metric style report.
The ChatGPT fingerprint
ChatGPT text tends to be suspiciously even: uniform sentence lengths, tidy transitions ("furthermore", "moreover", "in conclusion"), balanced clause structures, and a fondness for words like seamless, robust, and holistic. Individually harmless — together, a fingerprint.
Why we detect patterns, not models
Sahihly doesn't claim to identify one specific product. It measures the stylistic signals shared by ChatGPT, Claude, Gemini, and their successors — which keeps detection meaningful even as new models ship every month.
Flagged? Fix it in one click
When a passage scores high, jump straight into the humanizer: it rewrites the robotic rhythm into natural prose while preserving your meaning, then automatically re-checks the result and shows the before/after signal drop.
Honest limits
No ChatGPT detector is 100% accurate — anyone claiming otherwise is selling certainty they don't have. Heavily edited AI text can pass; distinctive human writing can trip alarms. Use scores to revise, never to accuse.
