A look inside the Inkbreaker engine

Prose Grade

The same engine that grades every Inkbreaker exercise and every draft in your editor, available for any passage you bring to it. Paste 50 to 5000 characters and see how the metrics land. The full product turns these one-off numbers into a practice loop with feedback, exercises, and progress over time.

Paste the same text twice and you'll get the exact same numbers, down to the third decimal. This is measurement, not opinion. Why no AI? Read our approach.
