buy-bye uses on-device AI to automatically lock Buy, Checkout, and Subscribe buttons on every shopping site — so impulse purchases can't go through.
Runs silently in the background. Only shows itself when you try to click a purchase button — and keeps the rest of the page exactly as the site designed it.
Starts reading the page from the first byte of HTML. Checkout buttons get locked before the page even finishes loading.
Gemini Nano classifies each button: real purchase action, or harmless link? Nothing about your browsing leaves your computer.
The blocked button keeps its exact shape with a subtle "Access Denied" overlay. The site still looks like the site.
Works on any shopping site — Amazon, Shopify, Best Buy, Shein — without per-site rules.
Identifies purchase buttons even when they're unlabeled icons or styled divs. No rule lists, ever.
Blocks paid upgrades while leaving newsletter signups and free trials alone.
Won't lock wishlist, "save for later," legal links, or "Learn more" buttons.
Counts purchases blocked and pulls real prices from the page to estimate money saved.
Replace the hard lock with a 1–60 second wait plus explicit confirm. A pause, not a no.
Works on sites that don't exist yet. AI generalizes; rule lists don't.
Gemini Nano runs entirely on your device. No cloud calls, no browsing profile built.
Install and it just works. No account, no setup wizard, no permissions beyond the tab.
Hard block or cooldown mode — you choose the level of resistance that fits your habits.
No. buy-bye uses Chrome's built-in Gemini Nano (the Prompt API) — everything runs on your own machine. No accounts, no servers, no telemetry.
Any shopping site. We don't rely on per-site rules, so Amazon, Shopify stores, Best Buy, Shein, Discord Nitro, X Premium, and anything that hasn't launched yet all work out of the box.
Turn on Cooldown mode to replace the hard lock with a short waiting period plus an explicit confirm. Or pause the extension for the current site with one click from the toolbar.
Add any domain to your per-site allowlist and buy-bye steps out of the way.
It reads the page's JSON-LD, microdata, and visible DOM as a fallback — so the Money Saved number is based on the real listed price, not a guess.
Free Chrome extension. No account. Nothing leaves your computer.
