Product Walkthrough
Explore Path E (Formative Loop) and Path B (Diagnostic Engine) — the two teacher tools that form the core Gradient workflow.
After class, share your lesson content with Grλdient. What you taught becomes the foundation for a targeted assessment built around your actual lesson.
30 seconds No lesson planning required Any subject
Gradient creates a targeted exit ticket based on what you actually taught — not a generic question bank. Items are targeted to your lesson objectives.
A Google Form is created instantly and sent to your class roster. Students see it on their devices before they leave the room.
Google Classroom sync Tiered difficulty Standards-alignedStudents complete the assessment on their phones or Chromebooks as a seamless close to the period. Response rates are high because it's short, targeted, and directly connected to the day's lesson.
Responses flow into Gradient in real time. You don't touch a spreadsheet.
5 minutes Any device Auto-scoredWhile you're wrapping up class, Gradient is detecting item-level patterns: which questions broke down, which students cluster together, where the class misconceptions live.
This is not a gradebook. It's a pattern detection engine applied to every response in every item position simultaneously.
Item analysis Misconception detection Group clusteringBy the time you check your phone that evening, Gradient has generated a specific, actionable plan for next class: which students need re-teaching, which concept to address, which students are ready to move forward.
Not a list of scores. Not "review with struggling students." A precise instructional sequence with the students named and the concept specified.
Actionable Student-specific Ready overnightOpen with (8 min)
Warm-up: Locus definition — what does "equidistant" mean geometrically? Target: Student_07, 11, 14, 19, 22.
Small group (12 min)
Group A (proficient, 9 students): Extension — perpendicular bisector as locus proof.
Group B (developing, 11 students): Q2 reteach with signed coordinate scaffolding.
Group C (foundational, 7 students): Distance formula fluency with Tom.
Export your scored assessment from Google Sheets, your SIS, or any gradebook tool. Gradient accepts any CSV where rows are students and columns are items.
Before any data reaches the analysis engine, student names are automatically replaced with anonymous tokens. FERPA compliance is architectural — not a policy, a code path.
Any gradebook export FERPA-compliant Student_01 anonymizationGradient applies Singular Value Decomposition to your item response matrix, extracting the principal components that explain the most variance in student performance.
This is the same mathematics behind every major psychometric instrument — now available to any classroom teacher in seconds, with no statistical training required.
SVD-based PCA No statistics knowledge needed Runs in secondsGradient's AI interpreter reads the item loadings from each principal component and generates assessment-specific dimension names — based on which items load heavily, what those items measure, and what those items measure.
These are not predetermined labels. λ₁ might be "Conceptual Understanding" today and "Spatial Reasoning" in a geometry unit next month. The labels emerge from the data, every time.
Auto-interpreted Assessment-specific No predetermined categoriesEach student is placed in PCA space — not just ranked by score. Their position reveals their cognitive signature: strong on λ₁ (conceptual) but weak on λ₂ (procedural)? That's a completely different intervention than the student with the opposite profile.
Two students at 72% are often in completely different positions in this space. Gradient shows you exactly where each one is.
Individual positioning Cognitive profile Intervention routingGradient generates a five-tab XLSX report: class scatter, individual profiles, item analysis, intervention groupings, and parent communication messages — all pre-written and ready to send.
The intervention groupings are based on PCA position, not score rank. Students are grouped by what they actually need, not by how much they got right.

This is the core insight Gradient was built around. Two students at 72% are often invisible to each other in a traditional gradebook — and receive the same intervention that helps only one of them.
