Why Not Just Use AI?

It's not another AI chatbot. It's a marking tool, built by a teacher.

Expect zero generic AI mush. You get a first pass in your own hand, calibrated to how you actually mark, that you read, change, and approve.

Your integrity stays intact.

You stay the assessor. It drafts, you decide, you approve every word. AI assists, a human decides, the way the national framework requires.

Individual to every student.

Each comment is built from that student's own writing and their real next step. Never one template stamped across the whole class.

Authentic, never generic.

Calibrated to your voice and your own marking, so it reads as genuinely yours. None of the AI mush a parent or colleague spots in a second.

Safe to bring to school.

Names are stripped before anything leaves your browser, with the count shown. An approval pack is ready for your Head of Department.

FAQ

Asked by teachers. Answered straight.

Is this cheating? Am I still the one marking?
You are the assessing teacher, full stop. Open Period produces a first pass, a draft judgement with its reasoning shown, for you to review, change, and approve. That teacher-in-the-loop design aligns with the Australian Framework for Generative AI in Schools: AI assists, a human decides.
Will it sound like me, or like a robot?
It calibrates to work you have already marked, so the first pass uses your voice and your standard. You read and adjust before anything counts. The point is to sound like you on your best day, not like a chatbot.
Is student work safe?
Names and identifiers are stripped before anything reaches the AI, once in the app and again on the server, with the count shown on every output. We do not store drafts, feedback, or prompts. Your work lives in your own browser. De-identified text is processed under commercial API terms and is not used to train models. Get the privacy and approval pack for your school →
Is it really free to try?
Yes. The free tools above need no sign-up at all. When the full app opens, founding teachers get every tool free for fourteen days, fifty AI actions, no card, nothing recurring. At the limit it simply stops, and everything you made stays in your browser.
How do I know the feedback is not made up?
Every first pass shows its working: the criteria it used and the evidence from the student's own writing. It is built on a verified evidence base and regression tested before every release. You are never asked to take its word, or ours.
What It Does

The whole week, drafted.

One tool for the jobs that eat your evenings. Every output is a first pass you finish, not a final answer it sends.

Marking

A first pass on every draft

Feedback grounded in the student's own writing, with the reasoning shown. Feedback only for Years 7 to 11, bands for Year 12.

Reports

A whole class of comments

Draft the full set in your register, calibrated to comments you have already written. Export when you are happy.

Parent Emails

The hard messages, handled

Warm, firm or brief. The tone you choose, the words you approve, sent from you.

Differentiation

One task, three levels

Adjust any worksheet or text for the range in your room, in minutes instead of a free period.

Slideshows

A lesson deck, started

A teaching sequence and slides from your text and outcome, ready for you to shape.

Your Students

It remembers the class

Student profiles tie marking, reports and emails together, so the picture builds across the year.
