## About Harvest with LuumenAI

Connect Harvest and your team can ask about clients, projects, tasks, and time entries without opening the web app. Luumen reads the account over OAuth2 and answers in the terminal. When it is time to raise an invoice, create an expense, or send an estimate, the change is shown first and waits for your approval by default.
