Design beautiful textbooks.
Export straight to Adobe InDesign.
Paperflo is a professional block-based visual editor built for educational publishers. Draft outline structures with Gemini, inject custom pedagogy rules, design rich callout components, and export clean, production-ready .idml files for print.
Pedagogical Framework: Constructivist Outline
Gemini has loaded prompt constraints: inquiry-based headers, visual callouts, and active learning check-points are enabled.
Force and its Effects
We experience forces in almost every action we perform in daily life, such as pulling a cart, opening a door, or hitting a ball. A force can set a stationary body in motion, or change the velocity of a moving object. Let us look at force from a fundamental perspective.
A block of mass 5 kg is pushed with a net force of 15 N on a frictionless surface. What is its acceleration?
a = 15 N / 5 kg = 3 m/s² (towards the direction of force)
A force does not just move things; it can also distort their shapes. For example, squeezing an orange, or compressing a spring. In the next section, we study Newton\'s three laws of motion.

Mathematics Preset
1.2 Gravitational Fields
A gravitational field is the model used to explain the influence that a massive body extends into the space around itself, producing a force of attraction on other massive bodies. Thus, it is a vector field representing the gravitational force per unit mass.
If f is continuous on [a, b], then the function g defined by g(x) = ∫ f(t) dt is continuous on [a, b] and differentiable on (a, b), and g'(x) = f(x).
By understanding how field values diminish according to the inverse-square law, students can construct accurate gravitational maps. In InDesign export, this frame maps directly to ObjectStyle: Callout_Frame.

Pedagogical Guidelines
Set book-wide teaching rules (e.g. Constructivist, Gamified, Inquiry-based) that prompt-inject when using AI writing drafts.
Safeguarded Deletion
Smart editor warnings protect manual block edits and customized outlines from being overwritten or lost.
Zero-loss XML IDML mapping engine
Paperflo doesn\'t just output styled HTML. It translates the visual canvas block-hierarchy into an Adobe InDesign XML story catalog. Paragraph Styles, inline fonts, lists, and callout bounding-boxes map to actual Adobe Object Styles.
- Preserves paragraph style linking in InDesign (Primary_Header, Solver_Body).
- Exports image placeholders as linked local image frame coordinates.
- Callouts compile to actual Object Styles inside native text frame threads.
- Outputs valid ZIP packages containing standard XML structures.
