Early access · being built with educators
PaprGrid is building a visual workspace that turns rough worksheets, notes, diagrams, and teaching material into structured documents teachers can review and refine.

What we’re building
Four planned chapters for a teacher-led workflow. These interface previews show the product direction while early access is still in development.
Bring in the way your work already exists: a phone photo, PDF, scanned worksheet, pasted question, or a page of handwritten notes.

Lesson preparation
We’re exploring a teacher-led path from rough lesson planning to a clearer resource that can be reviewed and refined.
lesson: quadratic transformations
y = (x − 2)² − 3
vertex (2, −3), axis x = 2
• compare with y = x²
• ask pupils to predict roots first
misconception: signs inside bracket!
