Hinter | Phishing, BEC & Scam Shield for Gmail & More

Phishing & wire-fraud guard for Gmail & Outlook. DMARC/BIMI, domain age, links, attachments + AI. Yahoo & iCloud too. Free tier.

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.
