Research-backed AI essay grader that gives teachers their evenings back
Score essays and open-ended responses against your own rubric or one of 500+ standards-aligned rubrics, with a written comment for every criterion.
Photograph paper essays from your phone or the copier, and CoGrader reads the handwriting, groups pages by student, and grades the whole set.
Import submissions from Google Classroom, Canvas, Schoology, Brightspace, Blackboard, DMAC, and more, then push grades and feedback straight back.
Flag possible AI-assisted writing and check submissions for plagiarism before you return feedback.
Honest screenplay coverage in 5 minutes.
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.
