YOUR KEY · YOUR OPENROUTER ACCOUNT

Connect to Jev

Run Jev through OpenRouter’s Decisions API using your own key. Each run uses your OpenRouter credits.

Saved in this site’s localStorage, unencrypted. Use a trusted device. Uncheck to keep the key in memory until this page closes.

Your key and input go directly from this browser to OpenRouter. They are never sent to this site’s server. OpenRouter and its model provider’s data policies apply.

Saving does not validate the key or make a paid call.
