# Stratum Shifts

> Weekly staff scheduling inside Claude, with a ChatGPT plugin in OpenAI’s review. A manager describes the team in the chat; Stratum Shifts fills the week within each person’s availability, roles and hour limits, flags clashes, finds cover and publishes one link staff open on their phones. Free for one workplace and up to 10 active staff. Team is a flat US$12 a month or US$120 a year, not per user and not per location, for up to 5 workplaces with up to 75 active staff in each.
