AI-Native Animation Engine • Freeware • Browser-Based

The Programmable Engine for Micro-Interactions

A lightweight tool for creating animated SVG micro-interactions—designed for AI agents and humans alike. Built on Paper.js, exposing a declarative API for understanding and manipulating vector space.

Research shows LLMs can reason about vector graphics through their textual representation. PinePaper provides the interface for agents to see, create, and transform objects in that space.

01. THE REALITY CHECK

Control Over Fidelity

Models like Veo, Sora, and Kling have achieved remarkable visual fidelity. They can render almost anything as pixels. But pixels are static data—you cannot easily modify a single element, interrupt a sequence mid-animation, or attach logic handlers to specific shapes after generation.

PinePaper bets on Visual Control. By exposing the vector DOM (Document Object Model), we allow AI agents to not just "dream" an image, but to structure it. This enables interruptibility, programmatic modification, and precise component reuse.

This isn't about replacing video generation—it's about filling the gap for functional micro-graphics: status indicators, data visualizations, UI components, and interactive diagrams.

The Vector Advantage

  • 1
    Readable Vector Space Agents can query positions, bounds, and relationships. The DOM is inspectable—enabling understanding, not just output.
  • 2
    Interruptibility Modify scenes mid-animation based on events. Essential for interactive dashboards and live data.
  • 3
    Micro-Signals Generate functional, lightweight components (spinners, badges, progress bars) rather than full-frame art.

02. RESEARCH CONTEXT

Following the Science

PinePaper's approach is informed by emerging academic research on LLM capabilities with vector graphics. These papers demonstrate that text-based vector formats provide a natural interface for language models.

These papers inform our design decisions but PinePaper is an independent project, not affiliated with any research institution.

03. USE CASES

From "Scenes" to "Signals"

PinePaper isn't trying to replace Hollywood VFX tools. We optimize for the high-utility layer that LLMs can master today: Functional Micro-Interactions.

Live Status Signals

"Recording" indicators, "Live" badges, or "Processing" spinners. Simple, code-defined animations that communicate system state without video file overhead.

PinePaper.create('circle', {animate: 'pulse'})

Data Accents

Context-aware overlays for charts. Use an Agent to analyze data and programmatically place animated arrows, highlighters, or callouts exactly where they matter.

PinePaper.annotate(chart, {highlight: 'Q3'})

UI Prototyping

Rapidly generate interactive UI mockups. Because output is DOM-based, these components can often port directly to production code.

PinePaper.exportSVG() → React component

04. ARCHITECTURE

The "Agent Hand-off"

Browser security sandboxes prevent external AI agents (like Claude) from directly executing code inside a running tab. We solve this with a transparent Human-in-the-Loop workflow, or via the Model Context Protocol (MCP).

1

Agent Reasons About Vector Space

The agent interprets your prompt, reasons about positions, shapes, and animations, then expresses that as code.

2

Execution Layer

You run the code (paste into console or via MCP tool) to render vector graphics locally. This keeps the tool free, secure, and client-side.

3

Iterate & Export

Refine with natural language feedback, then export as animated SVG, video (WebM), or static image.

Agent Output
// Agent creates animated status indicator
const dot = PinePaper.create('circle', {
x: 200, y: 150,
radius: 12,
fill: '#22c55e'
});

PinePaper.animate(dot, {
animationType: 'pulse',
animationSpeed: 1.5
});

05. FOUNDATION

Standing on the Shoulders of Giants

PinePaper is built on Paper.js—a mature vector graphics framework. Together, they provide the abstraction layer that lets agents understand and operate in vector space.

Paper.js

The Swiss Army Knife of Vector Graphics Scripting

Paper.js is a mature vector graphics scripting framework that evolved from Scriptographer—a scripting environment for Adobe Illustrator. It provides:

  • Vector-First Mathematics — Points, Sizes, and Rectangles as first-class citizens with operator overloading
  • Scene Graph / DOM — Nested layers, groups, paths, symbols—all inspectable and modifiable
  • Bidirectional SVG — Import, transform, animate, and export vector graphics seamlessly
  • Boolean Operations — Unite, intersect, subtract, divide shapes programmatically

Why Paper.js is AI-Friendly
// Vector math reads like math
const midpoint = (pointA + pointB) / 2;
const distance = (end - start).length;

// Scene graph is inspectable
project.activeLayer.children.forEach(item => {
console.log(item.bounds);
item.position.x += 10;
});

// Boolean operations
const union = shapeA.unite(shapeB);
const cut = shapeA.subtract(shapeB);

Code that reads like geometry — agents can reason about vector space through this syntax

We're Testing a Hypothesis

Can AI agents understand vector space and operate within it? The abstractions—PinePaper, Paper.js—are just the interface. The real question is whether agents can reason about positions, shapes, transformations, and timing to create meaningful visual output.

What we're validating:

  • ? Can agents reason about spatial relationships and coordinates?
  • ? Can they compose shapes, layers, and animations coherently?
  • ? Does the scene graph help them self-correct visual errors?

What works today:

  • Manual editor for text, shapes, and SVG import
  • 8 animation presets (pulse, rotate, bounce, typewriter, etc.)
  • Timeline editor with keyframe animations ✨ NEW
  • Export to animated SVG and WebM video
  • Global window.PinePaper API for programmatic control

Help us validate this — try the editor and share your experience via our feedback board.
