Custom instructions, personality, role, and project brief
Create an OpenRouter key at openrouter.ai/keys. Set a spend limit on the key (OpenRouter lets you cap credit per key) so a runaway chat can't cost more than you intend.
Your key is saved only in this browser. It's sent over HTTPS with each message so our server can pass it to the provider you chose; it isn't logged or stored.
Recommended. One key works for every model in the room.
