Read a lesson plan against UDL.

Paste a plan below. You get back what it already does well, where it leaves students out, and three specific changes worth making first, checked consideration by consideration against the CAST UDL Guidelines 3.0. Nothing is saved or stored.

Runs on an AI model, so treat it the way you would a colleague's quick read: useful, occasionally wrong, never the last word. It reads what you wrote down, not what you do in the room, and a lot of good UDL practice never makes it onto the page.
