See the shape of your writing, one bar per sentence.
Try it on
How it works: every sentence gets a bar, sized by how many words are in it. Bars close to your average length stay grey; ones that break away pick up colour. A wall of grey means everything is landing at the same size, which is almost impossible to notice while you are the one writing it. Variety is the number worth watching — it measures how far the length jumps from one sentence to the next. It all runs as plain JavaScript in this page, so unpublished drafts stay on your machine. Works offline once loaded.
