Process history
Every edit, every source.
On the record.
MATCHA can track all reading done in its built-in browser and all editing done in its built-in text editor. This creates a comprehensive, locally stored record of work that can be used to prove authorship. The complete record does not need to be shared to prove authorship, as MATCHA can produce certified .docx files (compatible with all major word processors) that summarize the work done.

In practice
How it works for student essays
For an at-home essay, enable Complete Work History before students begin and ensure your students do all their work in MATCHA, including reading. Use MATCHA Reading Packs to facilitate this. When submissions arrive, check the Writing and Reading Analysis for writing time, character churn, and how much of each cited source was read. Take a look at the replay and transcription analysis when an essay deserves a closer look.
-
Choose what gets recorded
Every project records its text edits. Add Complete Work History to record reading as well; it requires a browser allowlist, which minimizes the risk of recording private browsing.
-
Assess submissions at a glance
Each submission comes with work metrics that reliably indicate whether the student did the work themselves: writing time, character and word churn, time fragmentation, and AI transcription detection results will settle the matter in 95% or more of cases. Learn more about work metrics.
-
Dig deeper when in need
If need be, all the work can be replayed in a convenient viewer with variable speed, gap skip, and a timeline. The replay shows everything the student did, including scrolling through documents.
In detail
How each feature works.
What each feature does, its options, and what it requires.
Certified Edit History
- Every MATCHA project records the sequence of text edits used to produce the document.
- Edits can be replayed in the built-in player with a timeline view, gap skip, and variable speed.
- Edits are summarized in a Writing Analysis that can be added to MATCHA outputs.
Complete Work History
- Complete Work History adds recording capabilities to the built-in browser, including page loads, scrolls, and clicks. Reading patterns are recorded and reported as part of the Reading Analysis Report attached to MATCHA submissions, which shows how much of each cited work, other academic work, or other browsed page was read.
- Work history is stored locally in the project file using a tamper-proof format.
- Reading history can be aggregated between projects. For independent projects, select the projects to aggregate manually from Project Settings. For instructor-led projects, all submissions in the same course are automatically aggregated when Reading History Aggregation is enabled. This requires MATCHA Cloud submissions. Aggregated history is visible in the built-in grading tool only.
- While meant to be used as an assessment tool rather than a detection tool, this feature provides telling statistics that can be used to investigate AI misuse after the fact, such as character churn, writing time, and time fragmentation. It also has an experimental algorithm that detects AI transcriptions using 400+ attributes of the text editing history.
- To minimize the risk of inadvertently recording private browsing activity, this feature can only be enabled if browsing activity is restricted by an allowlist. History can be deleted by students.
Certified .docx
-
MATCHA outputs signed
.docxfiles that can be read by all major word processors and verified as having been produced by MATCHA with specific settings. - The .docx files produced for instructor-managed activities contain a cover page showing which integrity settings were enabled for the project, extensive editing statistics with a time/location graph, and, when Complete Work History is enabled, a reading analysis showing how much of cited and other works was read.
- A .docx file's authenticity can be checked using the verification tool in the MATCHA instructor menu.
