StoryNotes is an AI screenplay coverage service that reads your script and returns honest, structured feedback in about five minutes — letter grades, page citations and three concrete rewrites to try. Free to start, then $20 one-time with no subscription.
Upload a screenplay and receive structured analysis across genre and tone, premise and story engine, structure, theme and characters.
Each stage comes with a letter grade and clear highlights of what works, plus specific problems to address.
Feedback points to exact page numbers — for example, citing a scene at a specific page and line context — so notes are verifiable against your draft.
Rather than abstract advice, StoryNotes proposes three concrete rewrites you can try on your next pass.
