What is a Clark Attention Unit?

Clark measures the work it does on your manuscript in Attention Units. A quick question costs a few. A deep structural analysis costs more. Every account gets 30 AUs free each month — enough for consistent editorial feedback across a full writing session. If you run out, a top-up pack adds 30 more immediately. No monthly commitment.

Your work is always yours. Everything you write is stored in your own GitHub repository — safe, version-controlled, and fully accessible whether or not you have AUs remaining.
