WHAT IS K2F
K2F is an open document file format — like PDF or DOCX — that AI can easily design and edit, and that can be exported to different formats like Word, PowerPoint, Fillable PDF, and IDML.

Clean text exports and high-fidelity renders
Available in Playground, Desktop Reader, and CLI.
EFFORTLESS AI EDITING
Why Agents Love K2F
Restyle with a sentence. Fix without breaking layouts.
- 01
Zero-Friction Agent Editing
DOCX and PDF are hard for AI to manipulate safely. K2F separates content from styles, so agents like Claude or Cursor can rewrite content or restyle documents without breaking the layout.
- 02
Semantic-First Restyling
Want new colors, fonts, or denser text? Just tell your agent:
“Switch to a dark corporate palette and make headings bolder.”
K2F recompiles the theme without shifting the layout.
- 03
Design without the complexity.
AI can create sophisticated, modern layouts and visual effects without dealing with the complexity of Word or PowerPoint internals. K2F handles the hard formatting.
- 04
Deterministic Rollback
Every document is a semantic tree. Roll back changes, compare edits, and fix individual sections without affecting the rest.
WHY K2F IS DIFFERENT
| Feature | Traditional PDF | Word / DOCX | PowerPoint / PPTX | IDML | Native K2F Engine |
|---|---|---|---|---|---|
| AI Read & Write | Opaque & fragile | Complex OOXML | Complex shapes | Complex XML | Native semantic JSON |
| Document Export | Native | Native | Native | Native | Direct PDF, DOCX, PPTX, IDML |
| Fillable Forms | Manual setup | Limited | Not native | Not native | Native AcroForm generation |
| Layout Determinism | Fixed | Reflow-prone | Rendering-dependent | InDesign-dependent | Deterministic lockfile |
| Content / Style Split | Flattened | Complex | Complex | Complex | Clean content + JSON theme |
Traditional PDF
Opaque Black Box
Meaning trapped in static pixels
Text and layout are frozen into absolute coordinates. AI systems cannot reliably extract hierarchy or modify contents without breaking canonical geometry.
K2F Format
Semantic + Deterministic
Living semantic intent with pixel certainty
Content is expressed as a clean, AI-writable JSON tree. Appearance is governed by controlled primitives, guaranteeing 100% deterministic cross-device rendering.
Consistent like PDF. Editable like code.
HOW IT WORKS
Content in. Document out.
Your agent works with raw content.
K2F turns that into a finished document.

THE ADVANTAGE
Core advantages
Built from the ground up for AI-native document workflows.
AI-Native Read & Write
Structured semantic content lets agents edit with precision — zero layout drift.
Deterministic rendering
Same document = pixel-identical output every time, on every device. No drift, ever.
Semantically editable
AI edits meaning, not coordinates and colors. Precise node-level edits.
Precise rollback
Content is a tree. AI can revert to any historical node without touching the rest.
Self-contained file
Fonts, images, data all packaged into one .k2f file. Send it and it's complete.
Restyle the whole document at once.
K2F can apply the design system consistently across the entire document.

DESIGN PHILOSOPHY
Minimal Structure, Semantic-First Design
At its core, just two parts: content and theme. The engine handles all layout automatically for consistent output everywhere.
The content describes what the document means.
The theme describes how it looks.
The engine determines how it is laid out.
