What we built

The extension auto-detects the AI platform you are on (ChatGPT, Claude, Perplexity, Gemini, Grok), estimates the token cost of your prompt locally, and offers a one-click rewrite. All platform cost rules are built in — you never enter pricing manually.

What stays on your device

• Your prompt text, while you type, used to compute the cost estimate.
• Your settings and a per-day cost counter, in chrome.storage.local.
• A short preview of your last prompt, shown in the extension popup only.

What leaves your device

Nothing — until you click the Optimize button. When you do, your prompt is sent over HTTPS to our optimization endpoint, which proxies it to an AI model and returns a rewritten version. We do not log, store, or share prompt content. If the cloud rewriter is unavailable, the extension falls back to a local rule-based rewriter that never makes a network call.

No accounts, no tracking

The extension has no analytics, no accounts, no advertising identifiers, and no third-party trackers. The cost estimates and pricing rules are bundled with the extension.

Remote configuration

About every 12 hours the extension fetches a small JSON file from our hosted endpoint with the latest list of supported platforms and approximate pricing rules. Only that config file is requested — your prompts are never included.

Your controls

• Switch optimization to Local rule-based only in Settings to keep everything offline.
• Toggle the cost badge and Optimize button off at any time from the popup.
• Open the History page to export or clear your local log at any time.
• Reset to defaults or uninstall to clear all stored data.
