To put it simply, Words is a supplemental feature designed to support spelling and vocabulary development. A strong vocabulary helps learners read and type more efficiently—they recognize words quickly and don’t have to pause and think, which is often what slows down both reading and typing.

Typesy and Spreeder don’t require you to use this feature, but it’s available as an optional tool. Not all users may find it necessary, but it’s there for you to use at your convenience.

You can access this feature by clicking on the Words tab in Spreeder or Typesy. From there, you can either create your own word list by clicking on New Word List or Explore All to browse through a variety of premade word lists across different categories.
