An engineer, not a sales rep

What counts as a step?

One box on the canvas running once: a model call, a tool call, a rule or an approval. Waiting for a person doesn't count.

Which models can an agent use?

Any major model, or your own through an API key. You can pick a different model for each step.

What happens when an agent isn't sure?

It stops and asks. Any step can need a person's approval, and rules decide when, such as amounts over a limit.

Is our data used to train models?

No. Your data stays in your region, isn't used for training, and is deleted when your retention says so.

How long does setup take?

Most teams run their first workflow in a week. On Team and Enterprise we build the first one with you.
