Questions and answers

Does this work for Russian text?

Yes as a heuristic: it measures length, structure, and density. It does not pretend to be an exact Russian academic formula.

Why is there no AI text scoring?

AI analysis will be a separate provider-based tool. This one is deterministic and testable.
