What people are posting (in our words)

The business below is our own idea for solving this problem, not a company described in these posts.

Who it’s for

K-12 teachers, tutors and schools.

Adapt it to your industry

  • Start with one city, niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything that is sent in a customer’s name.

Step by step

  1. Ask 5 teachers for one rubric and three anonymized student answers.
  2. Write a prompt that drafts rubric-based feedback in the teacher’s tone.
  3. Build a simple web app with an AI app builder: paste rubric, paste work, get feedback.
  4. Offer a free tier and a teacher plan by Stripe; sell school licenses later.
  5. Share time-saved examples in teacher communities.
  6. Teachers always decide the grade; AI only drafts comments.

Ready-to-copy prompt

Here is my rubric [paste] and a student’s essay [paste, no names]. Draft short, encouraging feedback: two things done well, two specific improvements, linked to the rubric. Don’t assign a grade.

What they did

Teachers paste student work and a rubric; AI drafts feedback the teacher edits, cutting evening grading time. We designed this business around a problem people post about on X; it is an idea, not a report of an existing company.
