Your AI-powered partner for assessing English Writing
Super-granular diagnosis & more time to act on it.

We’ve developed an AI feedback system for KS2-3 writing that thinks like a teacher. It reliably captures the detail, not just the summary, so teachers and leaders can make informed decisions about what to teach next, and to whom.

The thinking of expert English teachers plus continuing teacher moderation equals reliable insight any teacher can action without the time your teachers spend now.
Human-centric workflow
On paper
Too often, implementing AI means more time in front of screens. Our process is optimised for paper — students write by hand, teachers scan their work via the document tray of the photocopier, and you get back paper-based feedback reports

Teacher-improved accuracy
With rigour
We mapped every micro-decision in the assessment of English writing, so teachers can see exactly where successes and errors are occurring. Our team of markers continuously improve our AI output — nothing is deployed until it is being marked as accurately as a human.

Unlimited marking
More practice
Even the most accurate and efficient teacher is a blocker to students receiving marked writing practice. Instead, unlimited student writing can contribute cumulatively to understanding their strengths & weaknesses.

Traditional workflow, modernised: AI support with a paper interface
How students learn hasn’t changed — so why change the way students learn? Our approach keeps students using a pen and paper — here's how it works.
1
Students work on paper
No change to existing lesson flows — students still work by hand
We'll send you a class PDF of lined sheets, each with a unique code at the bottom to help match students to their work.
Print the PDF before your lesson, then hand it out for students to write on.
They can cross things out, edit, and correct their work as usual.
