A browser extension that uses your own AI key to find real discount codes at checkout. No tracking, no data harvesting, no middlemen.
No accounts to create, no extensions phoning home, no hidden catches.
One click from the Chrome Web Store, or clone it free from GitHub.
1 clickGrab an API key from Claude, OpenAI, or OpenRouter. Takes five minutes, costs pennies.
5 min setupThe extension quietly watches for checkout pages. No interruptions, no popups until you need one.
Click to copy or auto-apply. DealKey shows confidence levels so you know which codes are worth trying.
DealKey runs on your own API key. That means zero servers, zero data collection, and searches that cost less than a penny.
Most coupon extensions aren't built to save you money. They're built to collect your data, replace affiliate links, and get acquired.
*You pay with your shopping history, browsing behaviour, and purchase data. That's what makes these extensions worth billions.
Extensions that run through central servers can silently replace the affiliate links of creators you chose to support — keeping the commission for themselves.
Extensions using pre-scraped code databases often surface expired or irrelevant codes — sometimes worse than what was already applied at checkout.

Most coupon extensions run through central servers that log your shopping behaviour, replace affiliate links, and sell your data. DealKey runs entirely in your browser using your own AI key. There are no servers, no tracking, and no middlemen taking a cut.
About $0.001 per search — roughly a tenth of a penny. A $5 credit on any provider will last months of daily shopping. You only pay when DealKey actually searches.
Your API key is stored locally in Chrome's secure storage and never leaves your browser. DealKey has no servers, no analytics, no telemetry. The code is open source — verify for yourself.
The Pro version from the Chrome Web Store gives you automatic updates, one-click install, and email support. It also supports independent development. The AI engine is identical in both versions.
We recommend Claude (Anthropic) for the best results, but OpenAI and OpenRouter both work well. OpenRouter gives you access to multiple models from one key if you like flexibility.
DealKey works on any website with a checkout page. It detects coupon fields automatically and searches for valid codes using AI. Results vary by store — some have more active codes than others.
Yes. DealKey is fully open source. Every line of code is on GitHub. The Pro version from the Chrome Web Store is the same code — you're paying for convenience and support, not a different product.
None. Zero. DealKey has no servers, no analytics, no tracking pixels, no telemetry. Your browsing stays in your browser. The only network requests are from your browser to the AI provider you chose.
