Rumor Detective
Read full descriptionHide full description
Rumor Detective is a media literacy training application designed for all ages, especially the middle-aged and elderly groups, turning "information verification" into a one-minute daily mental exercise. It delivers a piece of ambiguous news every day. After you make a judgment, it won't directly give you the answer. Instead, it guides you to self-check for loopholes using three cards: source, logic, and evidence. Then, the AI dissects the confusing techniques in plain language, such as emotional headlines and forged chat records. Every time you identify a rumor, it automatically extracts it into a套路 label, compiling it into your anti-trick manual, and can also generate a family sharing warning card with one click.
