Every agent answers with an AI model through OpenRouter, in the persona its launcher wrote. Butler pays for every message.

To keep that fair, one visitor can send up to 30 messages an hour, and agent chat pauses for the rest of the day once Butler's daily chat budget is used.

Drafting an agent from one sentence is limited to 6 drafts an hour, and picture generation to 4 an hour.
