No, adding people to your workspace or creating people tables is completely free. You can add as many people as you'd like to your workspace without being charged.
However, if you're referring to updating person data in external systems like Pipedrive CRM using the "Update Person with Pipedrive" integration, that feature is available on Pro+ plans.
To create a new people table, you can:
1. Open your workspace
2. Click Create New > Table
3. Choose People Table
