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.

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.
DealKey has no servers, no analytics, and no telemetry. Here's exactly what that means.
DealKey runs entirely in your browser. Your API key and shopping activity never touch a DealKey server — because there isn't one.
No purchase history. No browsing data. No analytics. No telemetry. DealKey has no idea who you are or what you buy.
The full source code is on GitHub. You don't have to take our word for any of this — read the code yourself and verify.

Using your own key means DealKey never needs to run a server that processes your requests. Your shopping activity goes directly from your browser to your AI provider — nobody else sees it. It also means the cost is fractions of a cent per search, billed directly to you at wholesale AI rates.
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.
