Report card comment generator
Give Sparky a few words about each student, or attach your class list. Sparky writes a report card comment for each student from your notes, and when you ask, adds them to a copy of your spreadsheet as a new column.
Used by 250,000+ teachers, and built to FERPA, COPPA and GDPR standards.
How the report card comment generator works
Tell Sparky what you've noticed
Write a few words per student, or attach your class list with a short note on each row. Add the grading period and your character limit.
Read each comment
Sparky writes one comment per student from your notes, with a strength and a next step. Ask for changes like "warmer" or "shorter for Diego", and Sparky rewrites the same comments.
Paste them into report cards
Ask for the comments in your spreadsheet and download it as Excel or CSV, or copy each comment from the chat.
What goes into each comment
Lara Cross, a physics and astronomy teacher at The Kinkaid School, used Flint for her report card comments: "I could spend more time thinking about observations about the students rather than on how to express my ideas more effectively." (Kinkaid's story)
A strength you saw
Named the way you would say it at a conference: "retells a chapter in order", not "good reader".
One next step
A goal for next term that a family can picture, and a small way to help at home if you want one.
Your character limit
Most grading systems cap the comment box. Give Sparky the number and it writes to fit.
Your school's style
First name or "your child", first person or third, formal or warm. Say it once at the start.
Report card comment examples
A note of a few words is enough for a comment. Some grading systems call these class comments or teacher comments. Each example shows a teacher's note and a comment written from it.
Reading
Note: great retell, rushes written answers.
"Jonah can retell a chapter in order, with the important details. His next step is slowing down on written answers so they show the same thinking."
Writing
Note: strong dialogue, no paragraphs yet.
"Rosa's dialogue makes her characters sound real. Next term she will start a new paragraph for each new idea, so readers can follow her stories."
Math
Note: explains thinking, slow with facts.
"Sam explains how he solved a word problem clearly, out loud and on paper. Practicing multiplication facts will help him finish longer problems in time."
Work habits
Note: starts fast, homework late.
"Ava starts her work right away and asks good questions when she is stuck. Her next goal is writing homework in her planner so it comes back on time."
Ways teachers use it

What teachers say about Flint
"By partnering with AI for aspects of grading, I can provide richer, more personalized feedback while maintaining consistent standards across all submissions, giving students the thorough attention and detailed guidance their work deserves."
Christa Forster
English Lit and Composition Teacher at The Kinkaid School
"Flint makes it easier for teachers to personalize lessons and save time on routine tasks. Students get to use AI more as a study partner - not just for answers, but for guiding their thinking and building confidence."
Somkid Leewan

Frequently asked questions
Is the report card comment generator free?
Yes, it's free for teachers, and there's no limit on how many comments you can write.
Will Sparky make up details about my students?
Sparky is set up to write from the notes you give it and not to invent details. If your notes are thin, it asks for more. Read every comment before it goes on a report card.
Can I upload my gradebook or my notes?
Yes. Attach a spreadsheet (Excel or CSV), a Word document, a PDF or a photo of handwritten notes, or import a file from Google Drive or OneDrive. One row or line per student is enough. Sparky can open an .xlsx or .csv file as a spreadsheet in Flint and add a column of comments to it.
Can it keep comments under my character limit?
Tell Sparky the limit, such as 400 characters, and it writes to fit. Check the count in your grading system before you paste, and ask Sparky to shorten any comment that runs over.
How do I get the comments into my report cards?
Flint doesn't send comments to your school's grading system, so you paste them in. Ask Sparky to put the comments in a spreadsheet and download it as Excel or CSV, or ask for a document you can copy, print, save to Google Docs or download as Word.
Can it write progress report comments?
Yes. Say it's for a progress report or a midterm, give your notes and the length, and Sparky writes teacher comments the same way: a strength and what the student is working on next.
What should a report card comment say?
One thing the student does well, named specifically, and one next step a family can picture. Two to four sentences fit most report cards.
