# Leina > Leina is an AI teammate that works in team chat and uses connected Apps and reusable Skills to carry out tasks. Leina uses OOMOL connectors and built-in services. Chat access and business-app access are separate: the data and actions available depend on connected accounts, supported tools, and account permissions.
