This is apparently powered by Substance, a JS library that implements a WYSIWYG editor, and which looks interesting. I wonder how it stacks up against the other leading JS-based editors such as ProseMirror, Quill and Draft, which are all quite solid at this point. (Unfortunately, some rudimentary testing shows that Texture is buggy to the point of being unusable — a lot buggier than I expect for a beta. For example, ctrl-Z to undo doesn't work in Safari and works awkwardly in Chrome; pasting doesn't preserve any formatting or semantic attributes; I can't seem to be able to modify (or even insert) any images; and it's pretty much completely non-functional on iOS.)
