NGT Studio

NGT Studio — User Guide

Everything you need to create, edit, and export documents with NGT Studio.

Contents

What is NGT Studio

NGT Studio is a browser-based AI document engine built for social posts, posters, flyers, brochures, and other designed documents. You describe what you want — an Instagram post, an A4 brochure, a presentation slide — and NGT generates a fully structured, styled document ready to export.

Unlike generative image tools, NGT produces a real document: every section is a separate, editable element with consistent typography and precise layout. The output is SVG — resolution-independent and print-ready. You can edit any section directly, refine the whole document with a follow-up instruction, and export to SVG, PNG, HTML, or PDF.

No design skills required. NGT handles layout, typography, and visual structure. You provide the content and intent.

Creating an account

Go to nextgentext.online/register to create an account. The 7-day free trial gives you full access to NGT Studio with no credit card required.

  1. RegisterEnter your email and a password and accept the terms. You are taken straight to your dashboard.
  2. Add your AI keyGo to Settings and add an API key for your chosen AI provider (Claude, GPT-4o, or Gemini). NGT Studio cannot generate documents without one.
  3. Open the studioClick Open NGT Studio on your dashboard. The studio runs in the browser — no download required.

Setting up your AI key

NGT Studio uses your own AI API key to generate documents. In Settings → AI Provider, choose a provider and paste its key. Keys are stored encrypted; only the key for your selected provider is injected into your studio session. Leave a key field blank when saving to keep the key that is already stored.

Recommendation

Claude (Anthropic) is the default and recommended provider for the most accurate layout and content generation. The active provider is shown as a badge in the studio header; switch any time in Settings without affecting your subscription.

NGT API keys are different: they authenticate your own applications against the NGT API. Create and revoke them on your dashboard or in Settings → NGT API Keys. A new key is shown only once — copy it immediately. Each key shows when it was last used and how many calls it made today.

Writing your prompt

The prompt is the only required input. Describe what you want in plain English. NGT figures out the structure, sections, content, and layout from your description. Press Ctrl+Enter (⌘+Enter on Mac) or click Generate.

What to include in your prompt

Prompt examples

Good promptInstagram square post announcing a summer sale. Bold headline, short body copy, and a discount code. Brand: Nova Skincare. Clean and minimal.
Good promptA4 brochure for Birchwood Coffee. Opening hero, three impact sections (carbon, water, sourcing), a stat row with key figures, and a closing call to action. Professional tone, earthy colour palette. Use the uploaded hero photo.
Too vague — add more detailMake a post about coffee.
Tip

Keep social posts and posters short: a headline, one supporting line, a few figures, and a call to action. Everything must fit on one canvas — NGT warns you when it does not (see Layout warnings).

Choosing a format

Pick a format in the format picker next to Generate, or name it in your prompt ("A4 portrait", "Instagram story", "16:9 presentation"). If you do not specify one, NGT infers it from your prompt. You can change the format later through Refine, for example "switch to Instagram story"; the document is re-laid out for the new size.

Formats fall into two kinds:

See the complete format list.

Brand and visual style

The prompt centre has two optional panels that are remembered between documents:

Palette and typography

The Style tab shows the design spec of the current document. Changes apply immediately to every section.

Colour palette

Eight colour roles: background, surface, surface alt, accent, accent light, text, text muted, and border. Edit a role with the colour picker, choose a preset palette, or ask in Refine ("dark mode with an orange accent").

Typography

Six type roles — Display, Heading, Subheading, Body, Caption, and Label — each with font family, size, weight, and line height. Any Google Font is supported. Display text can also have letter spacing, and OpenType features (ligatures, stylistic sets, figure styles) are applied where the font supports them.

Tip

If you leave the style blank, NGT chooses colours and typography from your prompt. Save a Visual style when you need brand consistency across many documents.

Font sizes and units

Font sizes follow the kind of format you are designing for:

Format kindSize unitWhat it means
Social, screen, digitalpx (plain numbers)Pixels on the canvas. A 1080 px Instagram post with a 120 px headline looks the same on every device.
Print (A-series, Letter, brochures, business cards)pt (e.g. 10pt)Physical points on paper, converted at the format's print resolution (150 dpi for paper sizes, 300 dpi for business cards). 10pt body text prints at 10 pt.

You can also use mm, in, and em in the size and letter-spacing fields.

On social formats NGT enforces readable minimum sizes, scaled to the canvas: at 1080 px, display text is at least 100 px, headings 60 px, body 28 px, and captions and labels 18 px. Wide banners scale these by their short side so the text still fits.

The canvas

After generation the document appears on the canvas. Use the preview toolbar to zoom (buttons, slider, or type a percentage), Fit the document to the window, and see the page count. Guides shows bleed and safe-zone guides for formats that define them. The prompt bar can be hidden to give the canvas more room.

Multi-page documents are shown as one continuous canvas; a dashed line marks each page edge. The dashed guides are never exported.

Editing sections

Click any section on the canvas to open the inline editor directly on top of it:

The Sections list in the Compose tab shows every section with its type, role, and heading. Click an entry to edit it in the full editor, or drag entries to reorder them.

Refining with AI

The Refine box (Compose tab) changes the existing document with a plain-language instruction instead of generating a new one. Press Enter to apply.

Refine instructionsMake the accent colour darker Use Playfair Display for headings Switch to Instagram story format Add a quote section after the stats Replace the stat values with: Revenue $4.2M, Growth 22%, Markets 14 Increase the side margins

Refine can change the palette, typography (family, size, weight, line height, letter spacing), layout margins and spacing, the format, the title, brand settings, and any section — update, add, remove, move, or change its background.

AI Elements and per-element regeneration

The header switch chooses how sections are drawn:

In AI Elements mode, click a section and choose ↺ Regenerate AI art to redraw only that element. You can add an optional instruction:

Regeneration instructionsMake it more colourful Add a gradient background More whitespace

Only that section is redrawn — the rest of the document stays exactly as it was.

Images

Upload JPG, PNG, GIF, WebP, or SVG files in the Images tab (drop them on the upload area or click to browse). Uploaded images appear in the gallery. Mention them in your prompt or a Refine instruction and NGT places them in an image section; image sections without an uploaded image show a placeholder you can fill later.

Prompt reference exampleUse the uploaded hero photo in the opening section. Add the product photo to the image section below the stats.

Layout warnings

After every render NGT checks the document and lists problems in the warnings panel (Compose tab). Errors should be fixed before exporting; warnings are advice.

CheckWhat it means
Content taller than the canvasOn single-canvas formats (posts, posters, flyers, banners) the content does not fit. Shorten text or remove a section — exports are cropped to the canvas size.
Text too smallPrint: below 7 pt is flagged, below 6 pt is an error. Screen: below 10 px is flagged, below 8 px is an error.
Line heightBody text below 1.2 and display text below 0.95 are flagged as tight; values that make lines collide are errors.
Brand violationA forbidden term from your Brand settings appears in the document text.
Contrast and structureLow text/background contrast, empty headings, and margin problems are reported with the affected section.

Research mode

The Research tab is a node editor for building a document visually. Drag nodes from the palette onto the canvas, connect their ports, and click ▶ Run graph:

Select a node to edit its settings in the Inspector. Select a node and press Delete to remove it; Clear empties the graph.

Saving and loading projects

Save in the header downloads the complete document specification as a .json file — content, sections, palette, typography, layout, and format. Load opens a saved file and renders it exactly as it was, so you can keep templates or continue work later.

Undo and redo

Every generation, refinement, and edit is saved to a 25-step history. Each step restores the complete document state — sections, specs, and layout.

Export formats

Export from the download bar under the canvas. What you see on the canvas is what you get: exports are made from the rendered preview, including AI Elements artwork.

FormatPlanNotes
SVGAll plansResolution-independent vector file. The document's fonts are embedded, so it looks identical on computers without them. Opens in Figma, Illustrator, and Inkscape.
PNG 2×All plansRendered at twice the canvas size (an Instagram post exports at 2160 × 2160 px) with embedded fonts. Single-canvas formats export at exactly the canvas size.
HTMLAll plansA standalone web page with real, selectable HTML text and your fonts — useful for web or email embedding.
PDFPaid plansOpens your browser's print dialog with correctly sized pages (A4, Letter, etc.) — choose Save as PDF. Fonts are embedded. Single-canvas formats produce one page; page formats produce one page per page on the canvas.
Tips

For social media use PNG; for print use PDF or SVG. PDF export opens a new window — allow pop-ups for the studio if nothing appears. If your connection blocks Google Fonts during export, the studio shows a notice and the file uses fallback fonts.

Section types

Every document is a sequence of sections. NGT picks the types from your prompt; you can change a section's type in the full section editor or ask for a specific type in Refine.

TypeUse it for
heroThe opening statement: large headline, optional subheading, left or centred.
headingA section title (levels 1–3).
bodyParagraph text, in one or two balanced columns.
featureA highlighted card with an icon, heading, and short text.
stat_row2–4 key figures with labels. Values share one size that fits every column.
quoteA pull quote with attribution.
listBulleted items.
columnsSide-by-side items, each with a heading and text.
image_blockAn uploaded image (or placeholder) with an optional caption.
tableHeaders and rows. Column widths follow the content; long cells wrap; numbers are right-aligned.
calloutA boxed note with an optional label, a bold heading, and text — ideal for a call to action.
timelineDated steps or milestones.
dividerA horizontal rule between sections.
captionSmall supporting text.
footerClosing line, contact details, or legal text.

Advanced settings

The Model panel in the prompt centre lets you override which models your provider uses: the full model for generating and refining documents, and the fast model for AI Elements artwork. Leave both empty to use the recommended defaults.

Collect training data stores your prompts and the resulting document specs in your browser (never on our servers). Export .jsonl downloads them, for example to evaluate or fine-tune your own models.

FAQ

Do I need design experience to use NGT Studio?
No. NGT handles all layout, typography, and visual structure from your prompt. You describe what you want in plain English and NGT produces the document.
Why do I need to provide my own AI API key?
NGT Studio uses your own key so you have full control over your AI usage and costs. Your key is encrypted at rest and only injected into your active studio session — it is never exposed or used outside your account.
Which AI provider should I use?
Claude (Anthropic) is recommended as the default. It produces the most accurate layout structure and content. GPT-4o and Gemini are fully supported — switch freely in Settings at any time.
Can I edit the document after it is generated?
Yes. Click any section to edit it inline, use Refine to change the whole document with an instruction, adjust the palette and typography in the Style tab, or regenerate a single section's artwork in AI Elements mode.
My post shows "Content is taller than the canvas". What should I do?
Posts and posters are a single fixed canvas, so everything has to fit. Shorten the text, remove a section, or ask in Refine: "make it fit — shorter body copy, fewer stats". Exports are cropped to the canvas size, so fix the warning first.
Why does my printed text look a different size than on screen?
Print formats measure text in points at the format's print resolution, so 10pt prints at a real 10 pt. On screen the page is scaled to fit the window. Check the size warnings — anything under 7 pt is flagged as too small for print.
What does the API call limit mean?
Each generation or regeneration call to the NGT engine counts as one API call. The daily limit resets at midnight UTC. Trial accounts get 20 calls per day. Paid plans get 500 (monthly) or 2,000 (annual) calls per day.
Can I export to PDF?
PDF export is available on paid plans (Monthly and Annual). It opens the print dialog with correctly sized pages and embedded fonts; choose "Save as PDF". Single-canvas designs produce one page, page formats one page per canvas page.
Can I use NGT Studio on my phone?
The website, your dashboard, settings, and this documentation work on phones and tablets. The studio itself is designed for a desktop or laptop screen.
Can I use NGT Studio for commercial work?
Yes. All output is yours to use commercially without restriction.
