Diagnostic math grading. Algebra through Pre-Calculus.

Diagnostic math grading. Not just what your student got wrong — why.

Upload a math test. Grade Sight reads the work, finds the pattern behind the wrong answers, and tells you one specific thing to work on next.

Algebra II · Unit 4 Quiz10 / 15
1. Solve for x
3(x − 4) = 18
3x − 12 = 18
3x = 30
x = 10 ✓
2. Solve for x
−2(x + 5) = 8
−2x + 10− 10 = 8
−2x + 10 = 8
−2x = −2
x = 1 ✗
Sign error
Distributed −2 as +10 instead of −10. Third time this month.
3. Factor completely
x² − 9x + 20
(x − 4)(x − 5) ✓

Built for two audiences.

One tool. Two ways to use it.

Grade a class set without losing the signal.

Most grading tools tell you who got the answer right. Grade Sight tells you what's tripping up your section — the students who can solve it, the students who flipped a sign, and the students who don't have the concept yet — and gives you something to do about it.

  • Class-wide pattern view. See which mistakes are showing up across the whole section, not just the student you noticed at lunch. When sign errors are spreading, you'll know before the unit test.
  • Grading that explains itself. Every wrong answer comes with a category — execution, concept, or strategy — and a short note on what actually went wrong. You can correct or override anything; Grade Sight doesn't pretend to replace your judgment.
  • Strategy cards your students will actually use. When a pattern shows up, Grade Sight produces a small, memorable card the student can tape to their desk. Not a worksheet. Not an intervention plan. A short framework they carry in their head until the habit sticks.
  • Longitudinal view per student. Track who's resolving what and who's stuck. Old weaknesses fading? You'll see it. Same error in the third unit running? You'll see that, too — honestly.
  • Printable practice sheets. When a pattern affects a cluster of students, generate a one-page practice sheet targeted at exactly that error. Print, hand out, done.
  • Privacy your district will sign off on. US-only data storage. No ad targeting. No school or district affiliation stored. NDPA signable. Built with district counsel in mind.

What the product does

Most grading tools stop at right or wrong. Grade Sight names the pattern behind the wrong answers — a sign error when distributing negatives, a skipped verification step, a concept that hasn't landed — and suggests one small thing to try.

Three things go wrong. We name which.

01 —

Execution

The student knows how to do it. They made a careless mistake — a sign flip, a copy error, a skipped step.

02 —

Concept

The student doesn't quite have the idea yet. The same kind of mistake shows up across different problems.

03 —

Strategy

The student gets there, but the approach is shaky. They don't check their work, or they freeze when their first method doesn't pan out. Grade Sight also tracks how sure the student is in their own answer. Confidence that doesn't match the work is its own signal.

Patterns over time

One test is a snapshot.
Six tests is a story.

Grade Sight tracks the diagnostic pattern across every assessment you upload. When an old weakness resolves, you'll see it. When one keeps coming back, you'll see that too — honestly.

The Negative Check

Before you move on, ask one thing.

“If the number in front was negative, did the sign of everything after it flip?”

Print. Tape it to the desk.
Use it for two weeks.
What the student gets

A small card the student can keep at their desk.

When a pattern shows up, Grade Sight suggests a short, memorable framework — something the student can carry in their head. Print it. Tape it up. Once the habit sticks, recycle it.

We store what's needed to track patterns over time, and nothing else. You can see everything we have. You can export it. You can delete it — all of it — in one click. No dark patterns. No retention loopholes. This page exists because we think it should.

Questions, answered.

What does Grade Sight do?+

Grade Sight reads your student's uploaded math work, grades it, and identifies the pattern behind any wrong answers — whether it's a recurring sign error, a concept that hasn't clicked yet, or a fragile strategy. For each pattern, it suggests one specific thing to work on next.

What grade levels and math subjects does it cover?+

Grade Sight covers secondary math: Algebra I, Geometry, Algebra II, Pre-Calculus, and Trigonometry, aligned to California Common Core standards.

How is Grade Sight different from Photomath or Gradescope?+

Photomath shows a student how to solve a problem. Gradescope is institutional grading software for college-level courses. Grade Sight does something different: it diagnoses why a student got something wrong — across many problems and over time — and gives the student or teacher one specific thing to work on next.

How much does it cost?+

Grade Sight is $15/month for parents and $25/month for teachers. Both plans include a 7-day free trial with no credit card required.

Do I need a credit card for the free trial?+

No. Your first 7 days are completely free, and we don't ask for a card until you decide to continue. If you don't, the account just stops at the end of the trial — no charge, no surprise bills.

Is my student's work private?+

Yes. We store only what's needed to track patterns over time: the uploaded assessment, the diagnostic categories per problem, and a timestamp. We don't sell student data, we don't use it for ad targeting, and we don't share it with third parties. You can export everything we have on your student, and you can delete all of it in one click. Data is stored in US regions.

What does my student see compared to what I see?+

You see the full diagnosis: the pattern, the suggested next step, and progress over time. Your student sees the strategy card — a short, memorable framework they can keep at their desk. The strategy card is designed to be useful to the student without making them feel diagnosed.

Can I cancel anytime?+

Yes. Cancel from your billing settings at any point. Your access continues to the end of the billing period, and you can export or delete your data whenever you want.

Privacy commitments
  • We never sell student data.
  • No advertising or behavioral profiling of students.
  • All data stored in US regions; deleted within 30 days on request.
