Warden — Privacy, Subscriptions & AI Guardian

See who's tracking you, kill forgotten subscriptions, and use private AI on any page. One guard for your whole browser.

Your browser has a bodyguard now. Warden has one job: protect you while you browse. It watches what sites do to you, what they charge you, and what they ask of you — and it tells you in plain English. 🛡 PRIVACY GUARDIAN (free forever) Every page is watched. Warden shows you by whom — trackers, advertisers, session recorders that replay your mouse and keystrokes, device fingerprinters, and cryptominers — and explains each one in plain English. Get a live privacy score for every site, one-tap tracker blocking, and an anti-fingerprint shield that scrambles your device signature so you can't be followed across the web. 🔁 SUBSCRIPTION KILLER (Pro) Warden spots free trials and recurring charges as you browse, tracks every renewal date locally, and warns you before your card gets hit — with a one-click path to cancel. It pays for itself the first time it catches a subscription you forgot. 🤖 AI PAGE ASSISTANT (Pro) Summarize, explain, or ask anything about the page you're on. Bring your own OpenAI or Anthropic key — your data goes straight to the model, never through us. 📝 SMART FORM FILLER (Pro) Fill applications and long forms from a profile you control. Warden always asks before it types a single field. PRIVATE BY DESIGN Tracker detection, subscriptions, AI keys, and form profiles all stay on your device. No telemetry. No account needed for the free tier. BUILT ON OPEN STANDARDS Warden uses the standard WebExtension APIs, so your protection works the same way everywhere you browse. Pricing: Free forever. Pro is $4/month or $29/year and unlocks the three paid modules.
