PAPRGrid · From rough source to editable document
PAPRGrid transforms worksheets, handwriting, equations, tables, and diagrams into structured, editable teaching materials you can review, refine, save, reopen, and export.
JPG · PNG · PDF · scan · handwriting · file-only or file + prompt
Four planned chapters for a teacher-led workflow. These interface previews show the product direction while early access is still in development.
Open a .papr project, or bring in PNG, JPG/JPEG, or PDF source material—including scans or handwriting—with an optional prompt to guide the result.

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!

Read vertex form, sketch the transformation, then verify intercepts.
y = (x − h)² + k → vertex (h, k)
Worksheet rebuilding
The product direction keeps source material visible while educators shape editable questions, equations, and diagrams.

REVIEW STAYS HONEST
PAPRGrid keeps the original beside the edited version. If a formula, label, or region needs attention, Review shows it instead of quietly guessing.
Each state stays linked to the original source.
Early-access interface concepts for proofs, investigations, worked solutions, and scientific figures—shown to invite educator feedback.
