Academic integrity, built into Google Classroom
Checkmark helps educators uphold fairness in the classroom with plagiarism detection, AI writing analysis, and unbiased autograding — all built into Google Classroom.
Our Philosophy
More Conversations, Not Accusations
Checkmark analyzes a student's revision history and actual keystrokes to show teachers exactly where AI-generated content was likely copied in. It gives you evidence to start a conversation, not an algorithm to hand down a verdict.
Forensics, not flags
Checkmark traces a student's revision history and keystroke data to surface where content was copied in rather than typed. You get a detailed picture, not a red stamp.
Conversation starters, not verdicts
There is no perfect AI detector, and we don't pretend otherwise. Checkmark gives teachers the evidence they need to have an informed conversation with a student.
Support teachers, not police students
Academic integrity isn't about catching students. It's about helping them learn. Checkmark is built to give educators better tools, not to make students feel surveilled.
