A weekly editorial on what AI quietly does to the things you buy.
Filed underShopping · Consumer Defense · Anti-affiliate
A Chrome extension that does live AI research per store, audits every code with Claude against its own counter-evidence, and charges you $3.99 a month so it never has to take a kickback at your checkout.
Editor's note
The free coupon tool ate the open web. We built ours so it can't.

The Investigation
Three observations that, taken together, only resolve one way.
Honey was caught hijacking affiliate links in 2024 — the extension silently overwrites the creator's referral tag with its own at the moment of checkout. Rakuten, Capital One Shopping, and Karma all monetize your cart in adjacent ways. The tool is free because you are not the customer; the merchant is, and you are the carriage.
— Bloomberg, ‘Honey’s last-click problem,’ Dec. 2024
The free extensions ship with a stale JSON of codes and politely type each one into the discount box. Half are expired. Half never worked. Coupon Hunter does live research per store, per session — Reddit threads from the last week, plus Brave Web — and re-scores every candidate twice with Claude before a single code reaches your screen.
— Verifier protocol, internal spec v0.7
Add up to 50 stores to a watchlist. The extension re-runs the verifier in the background on an adaptive cadence — the busier the store, the more often we look. The moment a code crosses the 80% confidence threshold, you get a push notification, often before SlickDeals or RetailMeNot have indexed it.

Field manual
Each one is source-verified — the AI cites where it learned a thing before that thing reaches you.
Tool · I
Pass one extracts code candidates with mandatory source quotes from Reddit and Brave Web. Pass two audits each one against its own counter-evidence — search terms like "expired", "doesn't work", "members only". Only verdicts of strong with ≥80% confidence reach you.
Tool · II
Pin up to 50 stores. The verifier wakes itself on an adaptive schedule and pings you when a new strong code lands. You can mute, snooze, or downgrade the cadence per store — the alerts are tools, not noise.
Tool · III
On product pages with structured data, we look for the same item elsewhere and let Claude filter knockoffs and wrong editions. Source-linked, not a scraped database. If the alternative is genuinely cheaper, you'll see it; if it's not, we say nothing.
Tool · IV
Claude reads the visible checkout text and returns up to three specific tips grounded in what the page literally says — "Add $4.25 to unlock free shipping at $50," "Click ‘Create account’ at the top for the first-order code." No invented deals. No generic advice.
Tool · V
We remember what you paid. If the same SKU drops within fourteen days on a retailer that price-matches, we tell you exactly which form to open with your order number pre-filled — not a vague reminder, an actionable link.
Tool · VI
We never inject an affiliate tag at your checkout. We never read your inbox. We don't ship analytics. Every AI-discovered code carries a clickable source URL so you can verify the evidence yourself. Your $3.99 is the entire business model.

Letters to the editor
Honey types a hardcoded list of common codes into the box at checkout and takes an affiliate kickback on your purchase. Coupon Hunter does live research per store, audits every candidate against counter-evidence, and takes no kickbacks at all. Your $3.99/month is our only revenue per user.
— The Editor
Live AI research costs real money per store, per lookup. A free, ad-supported model would force us to monetize you the way Honey does. Your subscription funds the Claude API calls and pays us to stay out of your wallet at checkout.

Yes — one click in the Stripe billing portal. You keep paid features until the end of your current billing period, then quietly drop back to the free tier. No retention dark patterns.
— The Editor
Yes — ten discovery calls per month, no watchlist, no price protection. Enough to test the verification quality on a handful of stores. Upgrade only if the proactive features earn it.

Shopify, WooCommerce, BigCommerce, Squarespace, and most generic cart layouts — roughly ninety percent of independent direct-to-consumer brands plus a long tail of boutique retailers.
