Certifiably human-made documents that aren't handwritten

MAT CHA

MATCHA is a writing environment that enables authors to prove their authorship by making the entire work-process transparent to recipients of their documents —from reading to editing. For exams and class activities, it offers a digital alternative to pencil and paper by blocking copy-paste, automation, or app switching. For home assignments, MATCHA further promotes academic integrity by facilitating in-person authorship assessment quizzes . With MATCHA, instructors no longer need AI detection or plagiarism detection.

Don't detect AI, preempt it.

Detecting and policing AI misuse is costly, ineffective, and fraught.

MATCHA's approach is to make AI misuse impractical so policing is unnecessary.

For educators

Three supervision models. One app.

In class

MATCHA prevents AI misuse on the student’s computer with Single-App Mode and Copy-Paste Control , while the instructor ensures no other device is used. Unlike locked browsers designed for taking exams on LMSes, MATCHA is a full word processor, which is both better for writing and better for preventing AI misuse. (Starting in August 2026, MATCHA can also act as locked down browser for quizzes.)

At home

MATCHA makes AI misuse impractical in unsupervised settings by recording and submitting the student's entire work process—including all reading, note-taking, and editing. By providing visibility into the entire process, MATCHA greatly raises the bar for plagiarism. MATCHA also facilitates in-person authorship assessment follow-up quizzes .

Supervised writing labs

A MATCHA-enabled innovation, supervised writing labs let students work on their own time. MATCHA's unique Check-In feature ensures students work on their assignments only while checked into a lab. By repurposing existing space and teaching resources, this new approach enables fair essay assessments in the age of AI while improving the student's experience through increased supervision and community.

We have AI too—Pedagogical AI

MATCHA comes with an optional AI assistant that can be configured to act as a tutor.

Optional AI assistant

AI that helps students learn.

MATCHA's optional, instructor-configured AI assistant can offer help with grammar, style, and, if desired, composition. Best of all, it has a pedagogical mode, in which it guides students to make their own corrections, facilitating learning.

An academic authoring environment that does it all

MATCHA Writer promotes academic integrity and productivity for all, from undergraduate students to professors.
