Stylus was founded by former teachers and education technologists with a clear mission: to make reliable, teacher-quality AI marking accessible to every school — no matter its level of technology. Unlike most AI tools, stylus works seamlessly with paper as the primary interface. Teachers simply print resources, students complete their work, and stylus handles the rest — delivering accurate, curriculum-aligned marking and actionable feedback without requiring 1:1 device access.
At the heart of stylus is rigour. Student work is transcribed through a multi-layered AI process that captures handwriting with better-than-human accuracy. Each response is assessed against nearly 100 teacher-authored criteria, rigorously validated to match or exceed human marker consistency. This ensures reliable, objective results at scale — without teacher oversight.
Data privacy is built in. All student work is anonymised before processing, and no student content is ever used to train AI models. Teachers receive class-level reports, confidence scores, and suggested interventions, while students get targeted, teacher-quality feedback and clear next steps.
Endorsed by the UK Department for Education and already transforming marking in schools nationwide, stylus combines innovative AI, deep classroom expertise, and robust quality assurance to save teachers time, protect student data, and raise educational standards everywhere.
