Inspiration
phishing is no longer obvious even normal users get fooled by realistic emails fake domains and ai generated text we saw people lose accounts and money so we wanted a tool that warns before damage happens not after
What it does
PhishFilter Pro scans emails urls and text in real time using 10 forensic engines and 5 ai models gives a verdict in seconds
chrome extension blocks phishing sites warns on password input shows real destination of links auto scans gmail
also sends alerts on telegram so users stay protected even on mobile
How we built it
backend with fastapi python async engines running in parallel
10 detection engines like domain age threat intel homograph detection sandbox preview
5 ai models combined for final decision using weighted scoring
frontend built on nextjs mongodb stores scan reports chrome extension uses manifest v3 and shadow dom
Challenges we ran into
manifest v3 service worker issues and no persistent timers
gmail dom changes breaking auto scan logic
llm disagreement on real vs fake emails
rate limits on free ai APIs
homograph attacks hard to detect visually
Accomplishments that we are proud of
real time detection under 7 sec with high accuracy
chrome extension that blocks and warns before user action
gmail auto scan with zero effort
fully working system on free tier
clean consistent ui across app extension and reports
What we learned
ux matters more than detection users must understand warnings instantly
ai ensemble is more reliable than single model
simple language works better than technical terms
browser limitations forced better architecture
Whats next for phishingo
launch chrome store version
add whatsapp alerts
build mobile support ios android
outlook integration for enterprise
