Edexia
Free AI essay grading calibrated to IB English and Australian senior English rubrics, with teacher-controlled feedback release
If you teach IB English or a senior Australian English course, Edexia is the most targeted AI grader in this category — it grades against your rubric rather than assigning a generic prose score, and the 81.2% exact / 98.3% within-one-band result from 579 St Bernard's College essays is evidence rather than marketing. The teacher review gate, editable comments and voice notes mean final judgment stays with you. The catch is scope: this is an English tool for IB, VCE, HSC, QCE and WACE, not a general assessment platform, so a maths or science department gets nothing from it. Compare against general-purpose writing assistants, which don't carry your rubric or the IB study list; here that

Skip Edexia if you need an assessment tool that marks outside English — it grades IB, VCE, HSC, QCE and WACE English only, so maths, science, humanities and language faculties get nothing from it.
Feedback release is gated behind teacher review mode, so someone has to sit and approve every script — the time saving arrives only if you build that review step into your week.
Edexia is positioned as free for teachers and students, which puts it in a different bracket from paid marking and assessment platforms — you are not trading budget for access here. The relevant comparison is scope rather than price: a general-purpose AI writing assistant costs money and still doesn't carry your rubric or the IB study list, while subject-specific assessment suites charge per seat and cover far more subjects than Edexia does. School leaders get a private walkthrough rather than

About Edexia
Edexia is a free AI essay grading and feedback tool built specifically for IB English and the Australian senior English curricula — VCE, HSC, QCE and WACE. Rather than scoring essays on generic prose quality, it grades against rubrics already loaded into the system: every criterion, grade descriptor and study design requirement is in place before you mark a single script. A team of experienced IB English educators develops the assessment context and validates the grading against real marking standards. The number the team leads with is accuracy: across 579 essays at St Bernard's College, Edexia matched teacher judgment exactly 81.2% of the time and landed within one grade band 98.3% of the time. A first step in the workflow lets teachers upload typed essays or scan handwritten work — Edexia transcribes handwriting automatically, then generates a grade plus paragraph-level feedback that references specific parts of the student's writing. You keep the last word: every AI comment can be rewritten, deleted or built on, you can record a voice note on any piece of feedback, and in teacher review mode nothing reaches students until you hit release. Around the grading itself sit cross-submission reports summarising each student's strengths, weaknesses and next steps, a prompt and stimulus library filtered by text, theme, command term and difficulty, blind grading with de-identified and randomly assorted scripts, benchmarking and calibration graphs, and moderation reports with visualisations of the judgement spread. AI detection is deliberately tuned toward false negatives — the team would rather miss some AI use than wrongly accuse a student — and writing replay shows an essay being written keystroke-by-keystroke, including pastes and tab-offs. School data is siloed per school, de-identified before AI processing, stored on Australian servers, never used to train models, and Edexia holds ISO 27001, SOC 2 Type II and ST4S accreditation. More than 50 schools use it, including Kolbe Catholic College, Marcellin College and Cranbrook School. It is a narrow, curriculum-specific tool, and that narrowness is why the rubric alignment holds up.
Behind the Verdict
Edexia's strongest asset is not the model underneath — it is the assessment context wrapped around it. Every criterion and grade descriptor for IB English, VCE, HSC, QCE and WACE is pre-loaded, and the team builds a text-specific knowledge base of themes, authorial intent and key quotes for each text on the IB study list, so a script on Things Fall Apart or The Handmaid's Tale is read against the right context rather than generic expectations. That is a real data moat and it is why the accuracy figures hold: 81.2% exact match and 98.3% within one grade band across 579 St Bernard's College essays. The workflow respects teacher authority rather than routing around it. Comments are editable, deletable or extendable; you can record a voice note on any piece of feedback; and teacher review mode blocks release to students until you approve. On the integrity side, AI detection is pitched toward avoiding false positives, and writing replay traces the essay keystroke by keystroke — pastes and tab-offs included — which supports investigation without presenting an AI-likelihood score as proof. The surrounding toolkit is deeper than most marking tools bother with: cross-submission reports of strengths, weaknesses and next steps; a prompt and stimulus library filtered by text, theme, command term and difficulty; blind grading with de-identified, randomly assorted scripts; benchmarking with graphs of marking tendencies; and moderation reports with visualisations. Data handling is sane for Australian schools — per-school silos, de-identification before AI processing, Australian servers, no training on your data, ISO 27001, SOC 2 Type II and ST4S. Where it falls down is breadth. There is no maths, science, humanities or language grading, no university-level English, and no documented LMS or API integration, so schools that require a marking tool to plug into Canvas, Moodle or an SIS will hit a wall. The rubric and knowledge-base work is also concentrated on a specific set of curricula, which is exactly why the alignment holds but also why it will be useless to a department outside that scope. If you are an IB or Australian senior English teacher marking at volume — especially with handwritten scripts — this is the most directly aimed tool available to you.

Real-world workflow fit
Concrete scenarios for the personas Edexia actually fits — and what changes day-one when you adopt it.
Upload 28 typed essays, let Edexia grade each against the IB Paper 1 rubric and draft paragraph-level feedback, then work through the drafts rewriting or deleting comments that don't match your read of the script.
Outcome: Students receive criterion-level grades and inline annotations days sooner than a manual marking cycle, and you have kept authorship of every comment released.
Scan the handwritten scripts alongside the typed ones, let Edexia transcribe the handwriting so all submissions are graded the same way, then run cross-submission reports to see which students keep missing the same criterion.
Outcome: Handwritten work stops being the awkward exception in your workflow, and the cross-submission view tells you what to reteach next lesson.
Put the same de-identified scripts in front of four teachers in blind grading mode, have each enter their grade before the AI's is revealed, then use the benchmarking graphs and moderation visualisations to talk through where judgements spread.
Outcome: The moderation meeting runs on evidence about the department's marking tendencies instead of anecdote, and the spread of judgements is visible to everyone.
Use Cases
- Grade a batch of IB Paper 1 essays against the IB rubric and review every AI comment before students see it
- Run blind grading so scripts are de-identified and randomly assorted, then compare your grade with the AI's
- Generate cross-submission reports to spot class-wide strengths and weaknesses in literary analysis
- Calibrate a department by having teachers blind-grade the same scripts and reviewing AI consensus advice
- Transcribe handwritten or scanned responses so they can be reviewed and annotated digitally
- Investigate academic integrity questions with writing replay, watching pastes and tab-offs in the essay history
- Find or build stimulus material quickly with the prompt library filtered by text, theme, command term and difficulty
Limitations
- Edexia grades English essays against IB, VCE, HSC, QCE and WACE rubrics specifically — there is no maths, science, humanities or language marking, and no university-level English.
- It works through a web browser, and no LMS, SIS or API integration is documented, so schools that need Edexia wired into an existing platform should verify that before committing.
- The accuracy figures (81.2% exact, 98.3% within one band across 579 essays) come from trials at St Bernard's College, so results elsewhere may differ.
- AI detection is deliberately tuned to avoid false positives, which means it will miss some AI use — treat the likelihood score as a signal to investigate, not as evidence.
- Handwriting transcription is offered for scanned responses but, as with any transcription, accuracy on poor-quality scans will vary.

Setup time & first value
How long it actually takes to get something useful out of Edexia — broken out by persona, not the marketing-page minute.
Teachers: you can be grading your first essay the same session you sign up — upload typed work or scan handwritten scripts, and Edexia transcribes and grades without a rubric-setup step because the IB, VCE, HSC, QCE and WACE rubrics are pre-loaded. Budget an extra cycle before you roll it out class-wide, though: the first marking run is where you learn how much editing the AI drafts need before
Switching to or from Edexia
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual marking in Word or Google Docs: upload the same scripts you'd mark by hand and use teacher review mode to keep your existing comment style while Edexia drafts the first pass.
- →From a generic AI writing assistant: switch because Edexia grades against your loaded IB or VCE rubric and uses text-specific knowledge bases rather than scoring generic prose quality.
- →From spreadsheet-based moderation: move the same de-identified scripts into blind grading and use the moderation reports to replace manual spread-of-judgement tallies.
- ↗To a generic writing assistant: export released feedback and rework comments yourself, since no other tool carries your IB or VCE rubric context.
- ↗To a full assessment suite: expect to rebuild rubric and criterion structures outside Edexia, and to lose keystroke-level writing replay in the process.
