Hi Natalie Quintero,
Appreciate your query over the Microsoft Q&A platform.
The online version of Microsoft Project is called Project for the Web. It is designed for managing projects online and integrates with Microsoft Planner.
Since you already have Planner and Project Plan 3, you can continue using Project for the Web as part of your subscription. Project Plan 3 includes both the web-based Project for the Web and the option to install a desktop version.
If you need more advanced features, you might consider Project Plan 5, which includes everything in Project Plan 3 plus additional capabilities.
You can find more details about the different plans and their features click here.
