Extensis Fonts

Free Google Docs and Slides add-on from Extensis that lets you preview, sort and apply over 1,400 Google Fonts from a side panel.

Our take: If you pick fonts in Google Docs often, the side panel with previews is quicker than the built-in menu, and it costs nothing.

Our takeIf you pick fonts in Google Docs often, the side panel with previews is quicker than the built-in menu, and it costs nothing.
It does not give you any font Google does not already offer. The permission list is broad for a font picker, so school and company admins may want to review it first.
Why we rate itFree, quick to install and makes Google Fonts easier to compare in Docs and Slides.
The catchSame fonts as Docs' own More fonts menu, and broad edit access to your Docs and Slides files.
