Which reads better?

Two versions of the same short text, side by side. Pick the one that reads better. There are 20 rounds and it takes about 10 minutes. You find out which version was which at the end.

How it works

Each round shows Version A and Version B of an email, a post, a cover letter or some talk notes. Read both and pick the one you'd rather get. If you can't tell them apart, say so. That counts too.

No sign-up. We only count which version was picked for each text, per day. Your progress stays in this browser, so you can stop and come back.
