Your own SI
In September 2026 the US government began calling artificial intelligence super intelligence — SI. The word changed. The work it does for your business did not.
-
No key from an AI provider
You need no account with an AI provider and leave no payment details there. You book the assistant, create an access token in your account and enter it in your tool. That is the whole setup.
-
You choose which SI answers
You pick that at the moment you pick the model, not in a support ticket six months later.
-
You will never get a surprise bill
More than you have paid for is never used. That is not a policy, it is how the meter is built.
