MarkMate is an AI-powered tool that helps teachers provide fast, tailored and detailed essay feedback to their students. The feedback includes numerical grades as a helpful guide, and suggested edits - with reasons - directly into the body of the text. MarkMate also collates all the grades into a single spreadsheet, so teachers can see how the class performed overall.

We have put together a little example where this essay is marked against this rubric, to produce some sample feedback.

MarkMate is here for teachers and students, at upper-primary schools, high schools and universities.

For teachers, MarkMate helps them provide the type of detailed feedback for their students they wish they had the time to give.

For students, MarkMate helps to guide them on how well their essays meet the teacher's rubric before they submit, increasing the quality of their work. The feedback is detailed, and the edits all come with clear reasoning.

For the moment MarkMate is free for everyone while we get your feedback. In time we'll set up subscription plans with special deals for schools and universities.

MarkMate will always be free for our mates in low-income countries, where we think it'll be transformative.

MarkMate is built on Microsoft's Azure OpenAI platform, which doesn't use any user data to train or retrain any of their models. Any files you upload to MarkMate are not available to other customers, or to OpenAI. For more details please visit Microsoft's Azure OpenAI Service privacy policy.

Essays should be submitted as a Microsoft Word document (.docx), which lets us provide detailed inline suggestions and comments. Please keep each essay under 1 MB, and include the student's name or student ID in the name of each essay file, so you can keep track of who's who.

You can upload multiple essays by saving them all in the same folder, and then during the upload process either (i) holding SHIFT to select a group of files or (ii) holding CTRL to select multiple files one-by-one.

The rubric should break the total marks for the essay down into different criteria. The Total Mark will then be the sum of the marks for each criterion. Include as much detail as you can - this is where the teacher can really tailor the feedback that MarkMate provides. See here for a sample rubric to get you started.

We prefer to think of MarkMate as a tool that provides "formative assessment" - feedback that helps students learn without counting towards their final grade. Students may find some bits of the feedback helpful, others less so. Importantly, they have the opportunity to decide how they take the feedback on board before submitting their final products.

We think that "summative assessment" - final grades - can have a huge impact on people's lives, and so are still best left to humans.
