AI Grading Assistant for Teachers

Grading by Hand Eats the Hours You Do Not Have.

The Problem

In-class handwritten work is some of the most honest work a student produces, and some of the slowest to grade. Students and parents now expect grades that are fast, consistent, and defensible. The studio reads each answer, a scanned handwritten page or a typed submission collected online, and drafts a score against your own rubric, criterion by criterion. You stay in charge on every single paper.

The Sample

Watch One Paper Get Graded.

Sample Only. Ms. Carla Jiménez, the AP Biology teacher from the Syllabus sample, gave the enzyme-lab short answer from that curriculum to her class and scanned their handwritten pages. Here is how The Rubric! Studio read and scored one student, Jordan Vega, a fictional student invented for this sample (the same student whose recommendation is drafted in the Letter sample). This is the full sample that used to sit on its own page, now built right into this one.

The Job

The Question and the Rubric

AP Biology Short Answer 3 Criteria · 10 Pts

Question Given to Students: An enzyme's reaction rate climbs with temperature, peaks, then falls off sharply. Explain what is happening at the molecular level across that whole range, and predict what a graph of rate versus temperature looks like past the peak.

The Rubric Carla Built

Mechanism (4 pts): explains collision frequency rising with temperature, then denaturation past the optimum.
Prediction (3 pts): describes the curve past the peak and ties it to the mechanism.
Use of Terms (3 pts): uses active site, denature, and optimum correctly, not as decoration.

The Scan and the Scores

One Paper, Criterion by Criterion

Select a criterion on the right to trace the sentences it scored in Jordan's scan.

The Scan, Transcribed

Jordan Vega – Enzyme Lab, Q3 As temp goes up the molecules move faster so they bump into the active site more often and the rate goes up. But after the best temp (the optimum) the heat shakes the enzyme so hard the active site changes shape; it denatures, and the substrate cant fit anymore. So the graph goes up to a peak then drops fast, and it doesnt come back down slow like it went up, it falls off a cliff because once the shape is wrecked its wrecked.

The studio transcribes the handwriting first, so you can read a hard-to-decipher page as clean text while you check the score.

Drafted, Yours to Change

Mechanism 4 / 4

High Confidence Both halves are here: faster collisions with the active site as temperature rises, and denaturation of the active site past the optimum. The "falls off a cliff" line shows the student grasps that denaturation is not gradual.

Prediction 3 / 3

High Confidence Predicts the up-to-a-peak-then-sharp-drop curve and ties the asymmetry to the mechanism (irreversible shape change), which is exactly the connection the criterion asks for.

Use of Terms 2 / 3

Medium Confidence Uses optimum, denature, and active site correctly. Drafted a 2 because "substrate" was implied rather than named.

Carla's Override → 3 / 3. "The prompt didn't require the word substrate, and 'the substrate cant fit anymore' uses the concept correctly. Full marks." The studio drafts; the teacher decides, and the studio records what she decided, not what it guessed.

No Override Recorded. The Studio's Drafted 2 / 3 Stands.

The Feedback Comment (Optional)

One Comment, Tailored per Student

Carla set a short comment for each score band once; the studio then wrote each student a personalized version. Jordan's, from the top band:

"Excellent, Jordan. You nailed the two-part mechanism and, more impressively, explained why the curve is asymmetric instead of just drawing it. Name the substrate explicitly next time and this is flawless. This is the write-up I'll be showing next period."

The Class Roster

Two Ways to Collect the Stack

Scanned Pages

Carla pasted her roster once, then uploaded a photo of each student's page. The studio read the name off each scan and matched it to the roster, flagging anything it wasn't sure about for her to confirm.

Collected Online

Prefer no scanning? Run the same job in Collect-online mode. Every student on your roster gets a private writing link and a due date, with no accounts to make. Pasting is off and the editor saves as they write, so what you grade is their own typing. Light signals like active writing time arrive as conversation starters, never verdicts.

Six Steps. From a Stack of Scans to Grades You Can Defend.

You own five of the six steps. The studio does exactly one: the first-pass draft.

Your Step The Studio's Step

Set Up

You

Create a Grading Job.

One question, plus your rubric. Each criterion has a label, its maximum points, and (optionally) a short description of what earns full marks.

You

Add Your Roster.

Paste your class roster, one name per line, optionally with a comma and a student ID. Save it as a class and your other teacher tools can reuse the same roster.

Collect

You

Add the Answers.

Upload scans as JPG or PNG photos, or a per-student PDF that becomes that student's answer, split into page images in your browser (up to four pages each). Or have the job collect typed answers online, where every student on your roster gets a private writing link and a due date you set.

Grade

The Studio

Start Grading.

It runs in the background, so you can close the tab and come back later.

Decide

You

Review Each Paper.

The scan or typed submission, the student it was matched to, a transcript of what was written, and a draft score with a rationale on every criterion.

You

Confirm, Override, and Export.

Confirm or override each line, then export the results as a CSV, an Excel workbook, or a printable PDF grade sheet. The recorded grade is the one you decided, not what the tool guessed.

Two Ways to Collect Work

Upload scans as JPG or PNG photos, or a per-student PDF that becomes that student's answer, split into page images in your browser (up to four pages each, and several photos can combine into one answer)
Or run the job in Collect-online mode: every student gets a private writing link and a due date you set, with no student accounts and no student emails
The online editor saves as they write and pasting is turned off, so what you grade is the student's own typing
Watch an online collection fill in live: who hasn't opened it, who's writing, and who submitted or ran late. Extend, reopen, or lock any one student's link
Scanned pages are matched to your roster by the name and student ID written on them, and an uncertain match is flagged, not guessed
Your rubric can be typed in directly or imported from a Word, Excel, or typed PDF file

What Comes Back on Every Paper

For scans, a transcript read from the page itself: handwritten prose, the math it reads written out, and what a diagram or sketch shows (typed answers are graded as submitted)
A draft score and a short rationale on every criterion, tied to the wording of your rubric
The same criteria applied all the way down the stack, so the tenth answer gets the same standard as the first
Light writing-process signals on typed submissions, like active writing time, as conversation starters, never conclusions
Your confirmation or override on every line, then export to CSV, Excel, or a printable PDF grade sheet. It is a consistency aid, checked by you, not a black box that hands out marks

Scans and typed submissions are stored privately in your workspace. Grading runs through an AI provider's API under terms that do not use your data to train their models, and we never use student work to train our own.

The Rubric! Studio is FERPA-aware and operates under your institution's direction; you remain the decision-maker on every grade. Built for teachers at US and international high schools, and for the department chairs and academic leaders who want consistent, defensible grading across every section.

One Class, Three Tools.

One fictional class runs through all three tools. Keep a class in your account and they share it: plan the course once, grade with its roster, and recommend its students with the work they actually did.

How the Handoffs Work

From This Class, End to End

Keep a class here once (a name and a roster) and all three teacher tools share it.
The Syllabus! Planner drafts the course, and each scan-gradable written assessment hands off to this studio as a ready-to-review grading job, questions and rubric already drafted.
Pick your class on a new job and its roster copies over, so you skip the paste step.
When you finish reviewing a student's grade, the row offers to draft their recommendation letter in The Letter! Desk, described in words, never as a raw score.

How This Sample Was Made

One Click between Each Tool

The question and rubric here came straight from Carla's curriculum in The Syllabus! Planner with one click. She graded the class against them here, with her final say on every score. And because Jordan is a student in this class, that graded work is ready as evidence when Carla writes a recommendation letter in The Letter! Desk, described in words, never as a raw score.

Fair Questions, Straight Answers.

What we would want to know before trusting a grading tool.

How Much Does the Rubric! Studio Cost?

Grading is free for every signed-in account, with no paywall and no per-page charge. A scan job holds up to 100 pages, at up to four pages per student.

What Can I Upload?

Upload your scanned answers as photos or as a multi-page PDF. Each photo is one page, and each page of a student's PDF is one page; a failed upload is never counted. Prefer no uploads at all? A job can instead collect typed answers online through private per-student links.

Can Students Type Their Answers Online Instead?

Yes. Create a job in Collect-online mode and each student on your roster gets a private writing link with a due date you set; no student accounts or emails are needed. Typed submissions land in the same review as scans, and you also see light writing-process signals, such as active writing time, presented as conversation starters, not conclusions. As they work, a live view shows who hasn't opened the link, who's writing, and who has submitted or run late, and you can extend, reopen, or lock any student's link individually.

Is My Students' Work Safe? What about FERPA?

Scans are stored privately in your workspace. Grading runs through an AI provider's API under terms that do not use your data to train their models, and we never use student work to train our own. The Rubric! Studio is FERPA-aware and operates under your institution's direction.

Does the AI Decide My Students' Grades?

No. It drafts a score and a short rationale for each rubric criterion, and you review every paper, adjust anything you disagree with, and decide the final grade. The recorded grade is always yours.

What File Formats Can I Upload?

Student answers go in as JPG or PNG photos, or as a per-student PDF that becomes that student's answer, split into page images in your browser (up to four pages each). Your rubric can be typed in directly or imported from a Word, Excel, or typed PDF file.

Does It Work with the Other Teacher Tools?

Yes. Plan a course in The Syllabus! Planner and each scan-gradable written assessment has a 'Build This in the Rubric! Studio' button that drafts the questions and rubric as a ready-to-review grading job; the curriculum then tracks each job's status, and every job links back. Keep a class in your account and a new job can copy its roster instead of pasting names. And once a student is matched to your class, their row offers to draft their recommendation letter in The Letter! Desk, with that graded work carried along as evidence.

Do I Need My School's Approval to Use It?

No. Your own free account is the whole setup: no institutional license, no IT ticket, no waitlist, and no roster sync, because you type or paste your class roster yourself. The studio is FERPA-aware and operates under your institution's direction, so handle student work the way your school's policies already require. Every recorded grade stays yours.
