Powered by the NGT Model

The AI engine that renders documents
inside pixel-perfect boundaries

Describe a document. NGT Studio generates the spec. The NGT model renders each section as SVG within its exact bounding box — no layout drift, no overflow, no guessing.

How it works

Prompt → Spec → Render

Describe your document
Write a plain-English prompt. Mention format, audience, content, style. Reference any uploaded images by name.
NGT generates the spec
Claude Sonnet produces a structured JSON spec — palette, typography, section order, all content. Real copy, never placeholder.
Layout engine computes bounds
The local layout engine calculates exact pixel coordinates for every section. No AI involved at this stage — instant.
NGT renders each element
In AI Elements mode, Claude Haiku generates raw SVG for each section within its computed bounding box. Sections stream in as they complete.
Iterate element by element
Hover any section → click ↻ Regenerate → type an instruction. Only that element is redrawn. Everything else stays untouched.
Export in any format
Download as SVG (pixel-perfect), PNG 2×, HTML (selectable text), or PDF (per-page, proper page breaks).
NGT Studio

Every format. Every section type.

A complete design environment in the browser. No installation. No subscription to a separate design tool.

📐
50+ document formats
A4/A3/A5, US Letter, all social media sizes, 16:9 presentations, business cards, email templates, posters and more.
🎨
Live palette editor
8 colour roles. 8 preset palettes. Hex pickers sync across the entire document in real time.
🔤
Typography system
6 type roles — Display through Label. Any Google Font. Canvas-measured baselines eliminate all text overflow.
🖼️
Image upload
Drop JPG/PNG/SVG images. Reference them by name in your prompt — Claude assigns them to the right sections automatically.
✦
AI Elements mode
The NGT model renders each section as raw SVG inside its bounding box. Sections appear progressively as they complete.

🔬
Research node editor
Visual API composer. Build document workflows with drag-and-drop nodes. Connect prompt, style, format, and section nodes.
↻
Per-element regeneration
Click any section → type an instruction → NGT redraws just that element. 25-level undo stack.
📄
Proper page breaks
Widow/orphan protection. Keep-with-next for headings. Table row splitting. Running title and page numbers on every page.

Prompt → complete document spec (JSON)
POST /api/ngt/edit
Spec + instruction → mutation commands
POST /api/ngt/element
Section + bounds → SVG fragment
POST /api/ngt/validate
Spec → warnings (font size, overflow, contrast)
