# How do tags work?

Every open note has a tag row under the title. Type a word and press Enter, a comma, or #, and the tag becomes a chip. The sidebar lists every tag you use, and clicking one filters the list to those notes. You can rename a tag everywhere at once, favorite it so it pins to the top, or delete it, with or without the notes under it.

Tags and folders solve different problems: a note sits in one folder but carries as many tags as you like, which is what you want when something is both "work" and "invoice". Imports tag by source, so everything that arrived from another app lands with its own tag and is easy to find, or to clean up later.
