Most AI checkers are not with you when needed. Leave the feed, upload a file, wait, come back. DotCheck scores images, video frames, and text live in Chrome. Colored dots and underlines on the page. More green means more likely real, red means more likely AI. Hover for a percent. Same in-house scores on the website and in the Android app when you share a file. Images, video, text, audio, and documents. After a score you can issue a report anyone can verify. A score is a signal, not a verdict.
