Ratio'd — Gmail Scam Risk Analyzer

Privacy-first scam risk analyzer for Gmail. Redacts PII client-side and injects real-time threat analysis. Developed by Vedant.

Ratio'd is a privacy-first, in-situ scam and phishing analyzer designed to protect your Gmail inbox from modern social engineering, brand impersonation, and deceptive links. Traditional email filters were built for an era of typos and clumsy phrasing. Today's AI-generated lures and quishing (QR code phishing) attacks are pixel-perfect and grammatically flawless. Ratio'd bridges the gap by injecting an isolated, lightweight security banner directly into your Gmail threads—providing instant threat scoring, plain-English explanations, and continuous learning from your feedback. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🌟 WHAT'S NEW IN VERSION 1.4.1 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • 🔄 In-Banner 1-Click Rating Overrides: Mislabeled a newsletter or want to trust an unfamiliar sender? Click [ 🛡️ MARK AS SAFE ], [ 🟡 PROMO ], [ 🟠 SUSPICIOUS ], or [ 🔴 UNSAFE ] directly in the banner to instantly reclassify it. • 🧠 Continuous Sender Learning & Address Inheritance: When you override a rating, Ratio'd remembers your decision! All past and future emails from that sender address automatically inherit your verdict across your inbox. • 📬 Pre-Box Inbox Row Security Badges: Color-coded security pills ([ 🟢 ], [ 🟡 ], [ 🟠 ], [ 🔴 ]) appear directly beside sender names in your inbox list before you even open the message. • 🏛️ Institutional Allowlist Safeguards: Pre-seeded zero-risk baselines for authentic community, educational, and school domains (e.g., balbharat.org) to prevent false alarms on verified institutions. • ⚡ Sub-5ms Local Cache Lookup: Instantaneous verdict retrieval powered by browser-local storage with zero perceived lag. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ KEY CAPABILITIES & FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Calibrated 0–100 Scam Risk Score Auditable, color-coded numerical risk score that breaks down why a message is safe, promotional, suspicious, or high risk. 2. In-Situ Neo-Brutalist Security Banner Mounts directly inside the open email view within an isolated Shadow DOM. No external popups, no context switching, and zero styling leakage. 3. Zero-Trust QR Quishing Shield Decodes and inspects embedded QR codes in emails using an in-browser bitmap decoder. Flags brand impersonation and credential harvesting paths concealed inside QR codes. 4. Safe Peek Zero-Execution Link Tracer Unmasks shortened URLs (e.g., bit.ly, tinyurl) before you click them using safe, zero-execution multi-hop HEAD requests that reveal the true destination domain. 5. Air-Gapped Client PII Redaction Your privacy is non-negotiable. Phone numbers, personal email addresses, and 4–8 digit OTP codes are masked directly in browser memory before any threat analysis. Raw personal data NEVER leaves your computer. 6. Grounded Flag Highlighting & Recovery Checklists Every warning highlights the exact verbatim text or domain pattern responsible for the flag. If an email is hazardous, Ratio'd provides a step-by-step incident response checklist to safeguard your accounts. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY & SECURITY FIRST ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • No Data Selling: We do not sell, rent, or monetize your personal information or email contents. • Local PII Sanitization: Redaction occurs client-side in volatile DOM memory. • Minimal Permissions: Operates solely on mail.google.com to analyze open messages and render security banners. • Open Source: Fully transparent and auditable codebase under the MIT License. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 GET STARTED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1.
