buy-bye

demo.mp4

A Chrome extension that locks buy and checkout buttons on shopping sites so impulse purchases can't go through. Clicks are blocked, the button is visually disabled, and a lock icon appears in the corner.

How it works

1. Detects purchase/checkout buttons on any page using Chrome's on-device Prompt API (Gemini Nano). Nothing leaves your device.
2. Falls back to keyword matching + payment-provider selectors (Shopify, Apple Pay, PayPal, Google Pay, Amazon Pay) when on-device AI isn't available.
3. Identified buttons are locked: clicks are blocked at the capture phase, aria-disabled is set, and the element is visually grayed out.

Toggle the extension from the popup to unlock everything instantly.

Install (unpacked)

1. Clone this repo
2. Go to chrome://extensions, enable Developer mode, and click Load unpacked
3. Select the buy-bye folder

Requires Chrome 138+ for the on-device AI path; older versions fall back to keyword detection.
