RedFlagger is a free, instant forensic analyzer for text messages. Paste any message — a text from an ex, an email from your boss, a message from a family member — and receive an objective breakdown across 8 psychological manipulation dimensions.
We use the Google Perspective API to detect toxicity signals, then map those signals to our custom 8-dimension model covering passive aggression, guilt-tripping, gaslighting, victimhood framing, deflection, narcissism, love-bombing, and silent threats.
The healthy rewrite feature is powered by Google Gemini and Groq Llama — both on their free tiers. RedFlagger is completely free, no login required.
