Edexia

Edexia is an AI essay grading and feedback tool for secondary school English teachers in Australia and for IB English. It supports QCE, VCE, HSC and WACE frameworks, with every criterion and grade descriptor preloaded so that grading matches the official rubric. The home page is currently framed around QCE teachers. Teachers stay in control of the output. They can edit, delete or extend any AI generated comment, add a personal voice note to feedback, and use a teacher review mode in which nothing reaches students until it is released. The vendor reports that across 579 essays at one school its grades matched teacher judgment exactly 81.2 percent of the time and within one band 98.3 percent of the time. Other features include a replay of a student's writing process that shows pastes, tab switches and AI likelihood scores, cross submission reports, a library of prompts and stimulus texts, and benchmarking and calibration for teachers who blind grade the same scripts. On privacy, the vendor says school data is not used to train its models, is de identified and is stored on Australian servers, and that it holds ISO 27001 and SOC 2 Type II certification. Some modules are in private access behind a waitlist. No pricing is published.
