The problem

Grading 30 essays shouldn't take your entire weekend

Manual grading is slow, inconsistent, and often less objective. Giving every student feedback on every issue by hand is impossible. The result? Minimal feedback, exhausted teachers, and students who don’t know what to improve.

From blank page to scored results in 4 steps

Set up once, score every time. Diagnote handles the heavy lifting so you can focus on teaching.

Build your assessment in minutes

Create tasks with free-text questions, multiple-choice, or fill-in-the-blank. Define your rubric criteria so the AI knows exactly what to evaluate.

Language Check

Five dimensions of language quality — analyzed automatically

Every free-text response is scanned for spelling, grammar, punctuation, expression, and vocabulary.

Per-student breakdown: Know exactly where each student needs to improve.

Class-wide overview: Spot patterns — is spelling a class problem, or just a few students?

Integrated with scoring: Language diagnostics feed into the overall assessment, not a separate tool.

Safe Exam Browser (SEB)

Secure exam mode — not just a normal browser tab

Lock students into a controlled exam environment where they can't switch tabs, open other sites, or leave the window.

Fully locked down: The device is restricted to the exam until the student submits. No other apps, no other websites.

Guided setup for students: Students outside SEB see clear steps to launch it — no confusion, no IT support needed.

One toggle, your rules: Enable SEB per exam and combine it with a PIN or join link for extra security.
