Three SwarmPlans on the house.

What counts as a SwarmPlan?

A Session you create. Reseeding an old plan into a new one counts. Sessions you delete still count. On Free that’s a lifetime trial; on Pro and Team the count resets every billing period.

What about hiring a human SME?

Per Session, separate from your plan. The SME sets their rate; you approve it before the engagement starts.
