When you reach a supported checkout, the extension tries every available code on your real cart, one by one, then applies the one that actually won. No stale databases, no guesswork, no overlay you can't close.

01gather

Codes come from everywhere.
We pull from all of it.

Most extensions read from one stale database that gets updated weekly. We continuously aggregate candidate codes from six independent sources per merchant, so the pool we test against is fresh, not curated.

A database doesn't know
whether a code actually works.

Codes expire, regions vary, members-only promos hide behind logins, stacked discounts misbehave. Lookups guess; live tests don't. We probe each candidate against your actual cart before showing you anything.

The best discount is not
always the biggest sticker.

A 30% banner can lose to a flat $25 once your cart total is computed. We rank by final price, not by what the code label says.

Shows you the work,
then gets out of the way.

When you reach a supported checkout, a small panel appears with the codes it's ready to test. You click, it tries each one, and you see exactly which code won and how much it saved. Then you continue to checkout as usual.

Fair questions.
Honest answers.

What people ask before installing, answered without the marketing gloss.

Is Coupon AI Assistant free?

Yes. No account, no payment. A 152 KB Chrome extension.

the coverage

Which stores are supported?

Over 14,000 stores. Candidate codes are aggregated from six independent sources per merchant and refreshed hourly.

Does it auto-apply codes without asking?

No. A small panel appears at supported checkouts; you click to run the test and see which code won before continuing.

Does it work on every browser?

Chrome only at the moment. There is no Firefox or Safari version yet.

How is it different from Honey or other coupon extensions?

Most read from a stale weekly database. This one live-tests every code against your real cart at checkout, then applies only the one that actually wins.

Does it collect my personal data?

No name, email, or payment data. Usage is measured anonymously in aggregate, and it never rewrites affiliate links.
