Your browser has a
bodyguard now.
Warden shows you exactly who's watching every page, kills the subscriptions you forgot you had, and gives you private AI on any site — all in one extension.
Four guards. One extension.
Most extensions do one thing. Warden replaces four — and they share one install, one price, and one place to look.
Privacy Guardian
Real-time detection of trackers, ad-tech, session recorders, fingerprinting and miners — explained in plain English, not jargon. A live privacy score for every page, plus one-tap auto-blocking and an anti-fingerprint shield that scrambles your device signature.
Subscription Killer
Warden spots free trials and recurring charges as you browse, tracks every renewal date, and warns you before your card gets hit — with a one-click path to cancel.
AI Page Assistant
Summarize, explain or interrogate any page. Bring your own OpenAI or Anthropic key — your data goes straight to the model, never through us.
Smart Form Filler
Fill applications and long forms from a profile you control — Warden always asks before it types a single field.
Start free. Upgrade when it saves you money.
The privacy guard is free forever. One Pro plan unlocks everything else — it pays for itself the first time it catches a subscription you forgot.

We can't see your data. By design.
Tracker detection, subscriptions, AI keys and form profiles all live on your device. Warden ships with no telemetry and needs no server to work. Your license is the only thing that talks to us — and even that is verified with a signature, not your identity.
Questions
Does it really work on Safari?
Yes. Warden is built as one cross-browser WebExtension and ships to Chrome, Edge, Firefox and Safari (via a signed Mac/iOS app). Most extensions skip Safari — Warden doesn't.
Will it break the sites I use?
No. The anti-fingerprint shield only perturbs the exact read paths used for fingerprinting, and every hook falls back to normal behavior if anything goes wrong. Auto-block is off by default so you're always in control.
Where does my AI key go?
Into your browser's local storage on your device, and from there straight to OpenAI or Anthropic when you ask a question. It never passes through Warden's servers.
How do I cancel Pro?
One click in the billing portal, anytime. Your free Privacy Guardian keeps working forever.
