Cordoval Labs is a set of browser-only AI tools. Paste a key from OpenRouter, OpenAI, Anthropic or Groq. It stays in localStorage on this device. The page calls the provider directly. There is no Cordoval server in the middle.

How we work
Privacy first
Your API key stays in this browser. Cordoval never receives it, and there is no Cordoval account.
No storage
Prompts and replies are not written to a Cordoval server. Refresh the page and the conversation is gone.
Bring your own key
OpenRouter is the default. OpenAI, Anthropic and Groq work the same way. You choose the model, and you pay the provider.
Direct calls
The browser talks to the provider over HTTPS. Nothing is proxied through Cordoval.
Clear anytime
The clear-key button removes the key from localStorage. Clearing this site's data in the browser removes it too.
Honest about limits
Model names, prices and how a provider handles data are theirs. Each lab says where the request goes.
The labs
One site. Your key.
Each lab does one job. Search or filter, then open it here at labs.cordoval.co.uk. Every lab uses the key in this browser.

How BYOK works
Your key. Your browser. Your bill.
BYOK means bring your own key. Cordoval Labs does not proxy your requests, so you keep the model, the cost, and the data path.
01
Pick a lab
Choose one tool. Every lab is a page on this site. There is no separate app domain and no API route behind it.
02
Add your key
Open the API key panel and paste a key from OpenRouter, OpenAI, Anthropic or Groq. It is saved to localStorage in this browser.
03
Go direct
Your browser calls the provider over HTTPS. Replies stream back token by token. Cordoval never sees the request.
No Cordoval server sits in the middle. Clearing your key in settings, or clearing browser data, removes it. Your prompts go only to the provider you choose.
