  Hinter helps you spot scams before you click, reply, or download anything. 🛡️
  
  Built for professionals and teams who rely on email every day, Hinter adds a silent layer of protection inside Gmail and highlights the signals that usually reveal phishing, impersonation, and fraud.
  
  Hinter analyzes what attackers depend on most:
  👤 Sender impersonation and lookalike domains
  🔗 Suspicious or misleading links
  📎 Risky attachments and hidden file types
  ⚠️ Urgent or manipulative language
  🧩 Mismatched identities that look legitimate at first glance
  
  Instead of generic warnings, Hinter shows exactly why an email is dangerous — so you can make fast, confident decisions.
  
  🚀 Why teams use Hinter
  - Detects risky emails before any action is taken
  - Flags impersonation attempts and fake senders 👥
  - Highlights dangerous links and attachments 🔍
  - Explains every alert with clear, actionable insights
  - Reduces costly mistakes from phishing and social engineering
  
  Whether you are a founder, operator, finance lead, or part of a growing team without a dedicated security department, Hinter helps you stay ahead of modern email attacks that traditional filters often miss.
  
  Protect your inbox. Protect your team. Protect your business. 🔐

  Hinter gives you a second opinion inside your webmail before you click a link, reply to a stranger, forward sensitive details, or download an attachment. It is built for professionals and small teams—especially roles that move money or sensitive files over email—who need clear reasons, not generic “this might be spam” banners.
  
  What Hinter looks for
  
  Hinter highlights the signals attackers rely on in phishing, impersonation, and BEC-style (business email compromise) messages:
  
  Sender authenticity — including DMARC and BIMI context, domain age, and patterns that suggest lookalike or spoofed senders
  Links — misleading URLs, redirects, and other red flags before you open anything
  Attachments — risky or unexpected file types and attachment behavior that often precedes malware or fraud
  Content pressure — urgent or manipulative language paired with identity mismatches that “look legitimate at first glance”
  Plain-language explanations — including AI-assisted summaries that connect the dots so you can decide fast, with confidence
  Hinter is not a replacement for common sense or your provider’s protections. It is an extra layer at the moment of action, focused on the targeted scams that traditional filters often miss.
  
  Where it works
  
  Hinter supports Gmail, Outlook on the web, Yahoo Mail, and iCloud Mail in the browser—so teams that live in webmail get consistent guardrails across providers.
  
  Plans
  
  Start on the free tier (includes daily full AI scan limits). Upgrade when you need higher limits for heavier inboxes or teams—Pro, and Business options are available (see pricing in the product or on the website).
  
  Privacy & trust
  
  Hinter is designed to be transparent: install only if it fits your workflow, review permissions in Chrome, and contact support if your organization has policy questions.
  
  Quick answers
  
  Will this slow down my email? 
  -Hinter is built to stay lightweight and out of the way until there is something worth surfacing.
  
  Is this only for “technical” users? 
  -No —explanations are written for operators, finance, and admin staff, not security engineers.
  
  Does it read my entire account without context? 
  -Hinter analyzes messages in context of risk signals you are already viewing; see the privacy policy for details.
  
  Install Hinter if you want explainable, inbox-native protection against modern email fraud—before the mistake happens.
