What This Tool Is and Is Not

FlagCheck is not a lie detector, medical diagnosis, or legal verdict. It provides conversational linguistic analysis and a second perspective to assist user judgment. We do not deliver moral judgments or definitive psychological diagnoses. FlagCheck provides structured semantic and conversational analysis to empower your own intuition.

Permanent Free Protection: Scam & Manipulation Warnings

Always Free

Scam warnings are never held behind a paywall. FlagCheck never declares someone a scammer arbitrarily; instead, it matches concrete linguistic markers and advises safety checks:

⚠Urgent OTP or verification code requests

⚠Emergency money transfers via 'changed new number'

⚠Pressure tactics combining manufactured urgency with strict secrecy

⚠Unverified third-party payment redirect links

⚠Impersonation of corporate helpdesk or customer support
