The suite includes 3 main tools –  WPS Writer, WPS Presentation, and WPS Spreadsheet, that are fully compatible with Microsoft’s Office Word, PowerPoint, and Excel, respectively; it also includes full support for PDF documents.

With one single account, you get access to the entire suite, anytime, anywhere. All your work is automatically saved in the cloud, no need to save anything locally.

As mentioned, the basic suite is free, with the possibility to upgrade to a paid plan, to have access to the full features. It’s worth a try!
