Phishing & Scam Email Detector

An email client or email plugin that uses AI to analyze incoming messages and flag phishing attempts and scam emails before users interact with them. Targets everyday users and businesses wanting better email security.

Email-based attacks are accelerating — the Anti-Phishing Working Group recorded over 1.3 million phishing attacks in Q1 2023 alone, and AI-generated phishing now bypasses traditional signature-based filters, creating genuine demand for smarter detection at the inbox level. Google and Microsoft both have built-in phishing filters, which is the real competitive threat here; any plugin has to meaningfully outperform what Outlook and Gmail already do for free, which is a hard bar to clear for most users. The $2k–$10k/mo revenue band is realistic only if the focus stays on SMBs willing to pay per-seat for compliance or cyber insurance reasons, since consumers almost never pay for email security add-ons. The most likely failure mode is distribution — getting users to install a plugin that touches their inbox requires a trust level most indie developers can't establish, and enterprise sales cycles will eat your runway before you hit meaningful ARR.
