What Edexia does

Edexia is an AI essay grading and feedback tool for secondary English assessment, with pages focused on VCE, HSC, QCE, WACE, and IB English. It evaluates essays against official rubrics, produces grades and written feedback, and keeps teachers in control of what students receive.

The workflow shown on the site starts with uploading or scanning an essay, continues with AI grading and paragraph-level comments, and ends with teacher review and release. The product also includes handwriting transcription, AI detection, writing replay, moderation, calibration, and other assessment tools aimed at classroom and school use.

Core capabilities

Typed upload and handwriting transcription

Upload typed essays or scan handwritten work. Edexia transcribes handwriting automatically so teachers can assess both formats in the same workflow.

Rubric-aligned grading and feedback

Grades are generated against official rubrics and descriptors, with criterion-level evaluation and paragraph-level feedback tied to the student's writing.

Teacher-controlled editing

Teachers can rewrite, delete, or extend any AI-generated comment, change grades, and add voice notes before releasing feedback.

Approval-based release

Teacher review mode keeps feedback private until it is explicitly released, so nothing reaches students before approval.

AI detection and writing replay

The system includes AI detection and writing replay so teachers can inspect a student's writing process and view pastes, tab-offs, and AI-likelihood scores.

Assessment support tools

Additional assessment tools on the site include prompt and stimulus libraries, blind grading, benchmarking and calibration, moderation reports, and cross-submission summaries.

Common ways to use Edexia

Teacher essay marking
Use the platform to draft criterion-level feedback for English essays, then edit the comments and grades before releasing them to students.
Handwritten script review
Scan handwritten responses so they can be transcribed and graded alongside typed submissions without a separate manual transcription step.
Department moderation and calibration
Run comparison, calibration, or moderation sessions to align marking across a department and inspect the spread of judgments.
Authenticity checking
Review writing replay and AI-detection signals when you need to check whether a submission may have been generated or assisted by AI.
Feedback for revision cycles
Use prompt libraries, cross-submission summaries, and next-step feedback to support iterative writing improvement across multiple submissions.

FAQ

How accurate is Edexia's grading?

Edexia is built to grade essays against official curriculum rubrics, including VCE English and IB English. Its source pages describe independent trials showing 81.2% exact match with teacher grades and 98.3% within ±1 mark, but it is still designed with teacher review in the loop.

How does Edexia handle essay submissions?

Teachers upload typed essays or scan handwritten responses. Edexia transcribes handwriting automatically, then generates rubric-based grades and paragraph-level feedback that teachers can edit before anything is released to students.

Which curricula does Edexia support?

The source materials say Edexia supports VCE, HSC, QCE, WACE, and IB English. The how-it-works page specifically details VCE English workflows, while the home page also highlights IB English calibration and rubric alignment.

Can teachers review feedback before students see it?

Yes. Teachers can rewrite or delete AI comments, adjust grades, add voice notes, and hold feedback in teacher review mode until they approve release.

What does Edexia say about privacy?

Edexia says student data stays siloed to the school or institutional account, is de-identified before AI processing, and is stored on locally based Australian servers. The site also says it does not train models on customer data.
