Band 5
Module A · first pass ✓ de-identified

Both Shelley and the film interrogate what it means to create life without accepting the duties of a creator. Frankenstein flees the creature he animates, and Tyrell builds replicants to serve and then expire, so both stage abandonment as the true monstrosity. This shows the composers warn us about ambition.

StrengthYou track the effect on meaning, not just the device.
Run-onOne idea per sentence — split where Tyrell enters.
NextTie “warn” to the exact wording of the question.
Why Band 5: sustained, well-supported analysis across both texts; tighten expression and anchor each point to the question to reach Band 6.

The week, marked.

Real first passes on the work that eats your week — shown in full, nothing cropped. You read, adjust, and hand back.

Marking a student draft: an annotated essay beside a feedback panel with overview, strengths and next steps. The marked draft showing in-text notes, each linked to a highlighted phrase in the student's writing. A parent email drafted in three tones side by side: restorative, firm and clear, and information-only. A student report comment generated three ways: achievement-first, character-first and trajectory-first. One task differentiated into three columns — Support, Standard and Extension — on the same topic. The worksheet builder options: style, page orientation, response area, tiers and sections. A printable Support worksheet: a modelled close-reading table, sentence stems, success criteria and key terms. A printable Standard worksheet: a comparative PETAL paragraph task with quote bank and self-check. A printable Extension worksheet: an evaluative task on form with critical lenses and a Band 6 self-audit.

Calibrated to you

Calibrated to you. And we show our working.

Upload work you have already graded, and the first pass calibrates to the standard you actually apply, module by module. Not a faceless average. Your standard, in your voice.

No tool can legally calibrate to NESA's marked sample answers, so anyone claiming it is guessing. We do the honest thing instead: we calibrate to the published standard and to your own marking, and we publish how often we agree rather than asking you to take our word.

Every teacher who marks with it sharpens the calibration. That shared record is the one thing a competitor cannot copy.

About the maker

Built by a teacher who did the marking maths.

I am an English teacher in training, finishing my degree at ACU. I built Open Period because I watched the maths up close. The pile that never shrinks. The evenings that do. And the feedback, the part that actually moves a student's writing, cut first every single time.

I did not want a tool that marked for teachers. I wanted one that gave the boring half of the work back and left the judgement exactly where it belongs: with you.

Fair questions

Asked by teachers. Answered straight.

Is everything really free to try?
Yes. Every tool, marking, feedback, differentiation, emails, reports, slideshows, syllabus check, is open during your fourteen day trial, with fifty AI actions, no card and nothing recurring. At the limit it simply stops, and everything you made stays in your browser.
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.
Is student work safe?
Names and identifiers are stripped before anything reaches the AI, once in the app, again on the server, with the count shown on every output. We do not store drafts, feedback, or prompt content. Your work lives in your own browser. De-identified text is processed by Anthropic under commercial API terms and is not used to train AI models. Always follow your school system's AI policy as well.
How do I know the band is not just made up?
The logic is anchored to the published NSW standards module by module, in our own words, and re-tested against a band tagged exemplar set before every release. No tool can legally calibrate to NESA's own sample answers, so anyone claiming that is guessing; we calibrate to the standard and to your own marking, then show our agreement instead of claiming it. After each mark you record the band you would give, and we publish how often the first pass lands within one band of your judgement, sample size shown. Even two human markers rarely agree on the exact band, so within one band is the honest measure. Any band it gives is an estimate for drafting and practice, never an official mark.
Why pay when ChatGPT is free?
A general chatbot is not calibrated to NSW standards, can give a different answer each time, can invent quotations, and pasting student work into it sits badly with most school policies. Open Period is the narrow opposite: module aware calibration that is regression tested, quotation checking against the actual set text, feedback in your own voice, and de-identification you can see.
