Sample draft

Every Saturday at 6 a.m., my aunt unlocks the laundromat on Fulton Street and I flip the forty-two dryers on one by one so the room is warm before anyone arrives. I have done this since I was eleven. The first customer is usually Mr. Okafor, who brings his shirts in a pillowcase and always asks me which machine is "lucky." At first the laundromat was just a job. I folded towels, swept lint, and counted quarters into paper rolls. But slowly I started noticing things. The woman who came at 7:15 always sat facing the door. The kids who waited with their dads did homework on top of the folding table because it was the only flat surface. When machine 17 started eating quarters, people stopped using it without telling anyone, like they had all agreed silently. I fixed machine 17 last winter. I watched a video, borrowed my cousin's screwdriver set, and found a bent coin slide. It took me three Saturdays. When it worked, nobody really noticed, but Mr. Okafor used it that week and said it was the lucky one now. The laundromat taught me that belonging is about paying attention. It taught me that small things matter and that you can make a difference in your community. I learned the value of hard work and responsibility. Now when I walk in, I know which dryer runs hot, which bench wobbles, and who needs a hanger without asking. I don't think anyone would call it a special place. But it is the place where I learned to notice what people need before they say it.

Voice

This detail has personality and humor and makes Mr. Okafor feel specific.

Asking for feedback saves an exact version. The feedback always belongs to that version, even after you revise.

A close read, not a grade

The reader looks at prompt fit, specificity, reflection, voice, and clarity. It tells you what comes through, what's hard to see, and up to three next edits.

Every comment points to your words

Before you see anything, the server checks each quoted passage against your draft. Anything that doesn't match exactly is withheld.

You write it. Goodmargin reads it.

  • Feedback comes as questions and revision goals, never replacement sentences. Nothing is inserted into your draft.
  • Story suggestions come only from experiences you’ve written down. With nothing saved, you get questions instead.
  • The application check shows when two pieces retell the same moment, with passages from both, and lets you mark it useful, intentional, or wrong.
  • A small, manual college list keeps prompts and dates you enter, clearly labelled as yours to verify.

What it won’t do

  • No admission predictions or chances. The rubric score is writing guidance, kept below the written feedback.
  • No AI detector, no plagiarism verdicts, no percentile rankings.
  • No ghostwriting and no automatic rewrites.
  • No selling or training on your writing. See exactly what AI receives.

What comes through
You come through as someone who pays close, quiet attention to a place and the people in it — the forty-two dryers, Mr. Okafor's 'lucky' machine, the bent coin slide in machine 17. The reader gets a real sense of competence and care built up over years of Saturdays.
What’s hard to see yet
It's harder to see what belonging actually feels like for you, as opposed to what you noticed or fixed. The middle paragraph states lessons ('belonging is about paying attention,' 'the value of hard work') rather than showing the feeling, so the emotional core of the prompt stays a little out of reach.
Next edits
  1. 1. Let the details carry the meaning instead of naming it
  2. 2. Show the feeling of belonging, not just the competence
  3. 3. Give the machine 17 story more weight
