What is Edexia?
Edexia is an AI-powered assessment marking and grading assistant designed specifically for educators, particularly those teaching VCE, HSC, QCE, WACE, and IB English programs. The tool provides automated essay grading and detailed feedback generation that is calibrated to official rubrics from examination boards like VCAA. Edexia achieves 81.2% exact match with teacher grades and 98.3% within one grade band according to independent trials.
Key features include automatic handwriting transcription so typed and handwritten essays are graded consistently, bulk upload capabilities for class assessments, customizable rubrics aligned to specific syllabus requirements, and LMS integration for seamless workflow integration. The platform offers an assessment dashboard for organizing and monitoring classes, detailed paragraph-level feedback that references specific parts of student writing, and the ability for teachers to add voice notes to feedback. Edexia supports both Text Response and Creating Text frameworks for VCE English, with built-in knowledge bases for every text on the VCE study list.
Edexia is designed for teachers, educational institutions, tutoring centers, and school leaders who want to reduce grading time while improving feedback quality. The tool saves educators up to 80% of their time on marking. Teachers stay in control by moderating all AI output - every grade and comment is editable before release to students. The platform learns like a teacher rather than generic AI, meaning it adapts to how individual teachers mark and follows that consistently.
The platform provides educational analytics including tracking how much time teachers spend on assignments and how many moderations are made, which school leaders can review. Edexia was founded in 2023 by Daniel Gibbon and Nathan Wang in Brisbane, Australia, and is backed by Y Combinator (YC W25).

Frequently asked questions about Edexia
What is Edexia and what is it used for?
Edexia is an AI-powered assessment marking and grading assistant designed for educational institutions to enhance learning experiences. It provides automated essay grading and detailed feedback calibrated to official rubrics like VCAA, saving educators up to 80% of their time on marking while improving feedback quality for students.
What about data privacy and security?
Edexia never trains on your data - it learns like a teacher, not an AI. All training data is siloed to individual or institutional accounts and remains their intellectual property. Data is de-identified, securely stored on Australian servers, encrypted in transit, and access is audited. No unsecured third-party access is allowed.
How much time does it take for a teacher to learn?
Effectively zero. Edexia is designed to be as intuitive as possible. Marking with Edexia is like moderating a colleague - you interact with it just as you would with another teacher, so there is effectively nothing new to learn. Most teachers don't even need a demo to understand how to use it, though constant immediate support is provided.
How many assignments before Edexia starts saving me time?
Hopefully zero. Edexia aims to be as accurate as possible right from the start using information provided during upload. Even if initially inaccurate, you only need to press one button and talk to it - it converts your input into perfectly written feedback. Edexia acts as an AI scribe helping you write feedback more efficiently, and progressively becomes more accurate over time.
Does Edexia integrate with existing educational tools like LMS/SIS?
Yes. Edexia works with each school to integrate seamlessly into their existing marking workflow, minimising change management and ensuring a smooth, quick, and painless implementation. It integrates directly into existing workflows and LMS without requiring formal training to set up.
Can Edexia be used in any subject or year level?
Yes. Edexia learns by understanding how you think. As long as the teacher is thinking critically while marking rather than arbitrarily assigning marks, Edexia can learn and follow that thought process. This may take longer in more complex and nuanced cases, but the underlying approach remains the same across any subject or year level.
Can I trust the accuracy of Edexia's grading?
Yes, because the teacher moderates its output and remains ultimately responsible for the accuracy of the mark. Initial accuracy may need improvement, but as you continue using the platform it improves. Since you train Edexia, it simply learns how you want to mark and follows that consistently, potentially becoming more trustworthy than your own judgment at some point.
What if the teacher does not moderate Edexia?
School leaders can track exactly how the platform is being used, including how much time a teacher spends on an assignment and how many moderations are made. This information can be reviewed to ensure proper usage. Teacher moderation is essential since they remain responsible for mark accuracy.
Can I change my plan later?
Yes. You can try Edexia for free for 30 days. If you want, a free personalized 30-minute onboarding call is provided to get you up and running as soon as possible. Plans can be changed after the trial period.
What rubrics and syllabi does Edexia support?
Edexia is calibrated to official rubrics including VCE (VCAA), HSC, QCE (QCAA), WACE, and IB English. Initial focus is on Year 11-12 QCAA syllabus with plans to expand to every year, subject, and syllabus globally. For VCE English, every criterion and grade descriptor from the VCAA rubric is built into the system, with knowledge bases for every text on the VCE study list.
