Edexia is an AI essay grading and feedback tool designed specifically for teachers, primarily serving the assessment work of VCE, HSC, QCE, WACE, and IB English courses.
Purpose: Edexia is designed to help teachers automate the grading and feedback process, save time, and improve assessment consistency. It is officially claimed to save 80% of grading time.
Main capabilities:
- Calibrated against official rubrics, supporting multiple curriculum frameworks (IB English, VCE, HSC, QCE, WACE).
- It is claimed to have an 81.2% exact agreement rate with teacher grading; in a test of 579 essays at St Bernard's College, it achieved "high-range consistency" with teacher judgments, and when not in exact agreement, it was usually only one band apart.
- Every criterion, level descriptor, and learning design requirement is preloaded, and a team of experienced IB English educators continuously develops the assessment context and validates the system against real rubrics.
- Teachers retain control: they can rewrite, delete, or supplement any AI-generated comment; record personal voice notes for feedback; and set "teacher review mode," where feedback must be reviewed and released by the teacher before students receive it.
- Provides playback of students' writing process, allowing review of pasting, tab switching, and AI likelihood scores.
- Generates an AI summary of all submissions for each student, covering strengths, weaknesses, and next-step suggestions.
- Provides hundreds of prompts filtered by text, topic, command term, and difficulty, and users can also paste their own prompts.
- Supports teachers in blind-marking the same script, aligning in calibration meetings, and then receiving charts and AI suggestions about grading tendencies.
- De-identified scripts are randomly assigned to teachers, who first enter their own grades before viewing the AI grade.
- Cross-checks scripts, views grade distributions, and generates visual review reports.
- Scans and transcribes handwritten answers, and is claimed to read better than most people.
How to use: Teachers can bring Edexia into the classroom. A waitlist is officially available, teachers and students can use it for free, and school leaders can request a private demo.
