Your keys, your browser

The Google Ads Builder runs entirely in your browser. API keys are encrypted in sessionStorage and never touch a server.

🔐

Session-Only Storage

API keys live in sessionStorage. Close the tab, keys are gone. Nothing persists.

🛡️

AES-256 Encryption

Keys are encrypted with Web Crypto API before storage. Even sessionStorage never sees plaintext.

🚫

Zero Server Calls

Your browser talks directly to the AI provider's API. We never proxy, log, or see your requests.

👁️

Open Source

Every line of code is inspectable. No hidden endpoints, no tracking, no analytics.

Pick your model

Bring your own API key from any supported provider. Each model has strengths — try them all.

It doesn't guess your copy.
It reads your page first.
Then it writes what converts.
