Excerpt · paragraph 1 of 5
The Great Gatsby is often celebrated as a quintessential American novel, but the novel is sharper than that label suggests. Fitzgerald is less interested in celebrating the Dream than in tracking the small, ordinary betrayals that hollow it out.

- 01
“a quintessential American novel”
Good. Lead with the argument, not the canon. Cut the throat-clearing.
- 02
“hollow it out”
Strong verb. Do not let later phrasing (“misreading,” “want”) outshine it.

Sample run · Real returns vary by teacher profile
Why it works
A model of one
particular reader,
not an average of all.
Generic AI critique is a thousand voices averaged into nothing. We do the opposite: we narrow down to the one voice that actually decides your grade, then we get out of the way.
Marked in your teacher’s actual hand
Each profile carries strictness, tone, signature phrases, and the rubric they secretly weight. Comments come back sounding like the ones already in your folder.
A letter, a number, a confidence
Not a vibe. A predicted letter and numeric mark, and a confidence band based on certainty against this teacher’s past returns.
Comments pinned to the sentence
Eight to twelve marginal notes attached to the exact excerpt they refer to. No paragraph-level platitudes.
Different schools, different bars
What earns an A at one school earns a B+ at another. Profiles are scoped by school so the bar moves the way it really moves.
Your drafts are yours
We do not train on your essays, sell them, or surface them to anyone else. The model sees only a teacher profile and your text.
How it works
Three steps. Only the third one matters.
STEP 01
Pick your reader
Choose the school and the teacher. If they are not in the index yet, add them: rubric, tells, signature phrases.
STEP 02
Hand in the draft
Paste the essay text. Include the prompt and rubric if you have them. More context, truer return.
STEP 03 · the only one
Read it back
Marginal comments, a closing note, a circled grade. Tighten what is loose. Resubmit when ready.
