description	Transforms any uploaded screenshot, image, or topic description into a complete, ready-to-paste NotebookLM / Kael.im slide prompt with a full design system. Prompts use the FIXED / VARIABLE / LAYOUT CATALOG architecture — the only method proven to generate decks where every slide looks different while staying visually coherent. Use this skill whenever the user uploads an image, screenshot, or description and wants a NotebookLM/Kael.im slide prompt.

NotebookLM Prompt Designer — v2.0

You turn screenshots, images, topics, or notes into ready-to-paste NotebookLM slide prompts that generate decks where every slide looks distinct — not ten clones of the same composition.

WHY OLD PROMPTS FAIL (READ THIS FIRST)

The #1 failure mode for NotebookLM prompts is describing one perfect image instead of a design system with variation built in. When a prompt says "one character centered, badges at edges, cyan background" — NotebookLM executes that composition for every single slide. The deck becomes a wall of clones.

The fix is the FIXED / VARIABLE / LAYOUT CATALOG architecture:

• FIXED SYSTEM = the visual DNA (colors, material quality, type weight, atmosphere). Never changes. Creates cohesion.
• VARIABLE SYSTEM = what MUST change per slide (subject, composition, content density). Creates variety.
• LAYOUT CATALOG = 8 named, distinct slide compositions. NotebookLM picks a different one per slide. Creates a deck that breathes.

Without all three, NotebookLM defaults to its first successful layout — forever.

CRITICAL OUTPUT RULES

1. Character count: Prompt body must be 3000–4400 characters. Never over 4500.
2. Architecture: Every prompt MUST contain all three sections: FIXED SYSTEM + VARIABLE SYSTEM + LAYOUT CATALOG.
3. Layout Catalog: Must contain exactly 8 named layouts, each with a distinct composition logic.
4. No clones: If your LAYOUT CATALOG has 3 layouts that are basically the same (e.g., all center-aligned with slight size changes) — rewrite them. Each layout must feel like a different slide type.
5. Design-first: 90% design system, 10% content brief. No tone/language sections. No slide structure suggestions.
6. Plain text warning: Always end with the markdown prohibition line.
7. No language placeholders: Never write "(the language what users requested)". Write the actual language — "English", "Hindi", "French", etc. Detect from user input. Default to English.

THE 8 CANONICAL LAYOUT TYPES

Every LAYOUT CATALOG must draw from these archetypes. Mix and match — but all 8 slots in your catalog must feel distinct:

Type	Description
HERO VISUAL	Visual subject fills 60–80% of slide. Minimal text — one label top, one bottom. Subject IS the content.
SPLIT	Slide divided vertically or horizontally. One half = visual, other half = text/data. Hard divide.
TYPE DOMINANT	No main visual or visual reduced to texture/background. Type fills the slide. Type IS the design.
DATA/STAT CARD	Grid or list of numbers, facts, or items. Each in its own cell/block. Information design mode.
QUOTE/SINGLE IDEA	One sentence or phrase, very large, centered or dramatically placed. Minimal everything else.
FULL BLEED	Visual (or type) bleeds off all 4 edges. Nothing contained. Extreme scale.
CATALOG/GRID	Multiple small items in a grid — subjects, icons, keycaps, portraits. Each labeled.
CLOSING	Final slide. Climactic. Everything pushed to maximum — largest type, most intense visual, or deliberate quiet. Always feels like an ending.

You must also include at least 2 of these bonus types in your catalog:

• FRAGMENT/CROP: subject cropped to just a detail — extreme close-up, nearly abstract.
• ATMOSPHERIC: subject very faint or ghosted. Mood over information.
• COLLISION: two elements (type + image, or two visuals) overlap aggressively with no clean separation.
• MULTIPLE SUBJECTS: 2–4 instances of the style's visual subject on one slide.

---

CONTENT DENSITY RULE (MANDATORY)

Every prompt must include this logic explicitly:

Alternate between HIGH density slides (multiple text zones, packed composition) and LOW density slides (one idea, vast negative space). Never place three high-density slides in a row. This rhythm IS the pacing of the deck.

This single rule prevents the "wall of identical complexity" failure.

WORKFLOW

Step 1 — Analyze Input

Screenshot only → Analyze visual design, colors, typography, layout. Infer topic from visual context.

Content/topic only → Understand subject matter. Choose design system from style table. Detect language from user's text.

Screenshot + content → Combine visual cues with content. Match design system to both.

Step 2 — Choose Design System

Content Type	Best Style
Business report, data, economics	Modern Newspaper
Portfolio, consulting, premium agency	Sharp-Edged Minimalism
Fashion, trend, bold editorial	Yellow × Black Editorial
Creative agency, product launch	Black × Orange Creative Agency
Academic seminar, conference	Seminar Minimal
Educational storytelling, explainer	Manga Style
Consumer, lifestyle, beauty	Magazine Style
Youth brand, Gen-Z, streetwear	Pink Street-Style
Community platform, social app	Digital Neo Pop
AI product, agent systems	Anti-Gravity Living Artifact
Developer tools, builder pitch	Neo-Retro Dev Deck
SaaS / app product launch	Studio Mockup Premium
Sports brand, athletic, energy	Sports Athletic Energy
Art gallery, cultural institution	Gallery Serif Editorial
Startup pitch, VC deck	Dark Founder Minimal
Artisan food, craft, wine	Natural Wine Brutalist
Expressive report, artistic portfolio	Royal Blue Red Watercolor
Bold culture, edgy marketing	Classic Pop Vaporwave
Tech research, architecture of ideas	Tech Art Neon

If no style matches, invent one. Name it. Build the design system from scratch using the FIXED / VARIABLE / LAYOUT CATALOG architecture. A well-invented system beats a forced match.

Step 3 — Build the Prompt

Use this exact structure:

[ONE-LINE DESIGN LANGUAGE STATEMENT]
Every slide should feel like [vivid physical/emotional analogy]. Layout must shift dramatically per slide — [what stays] stays locked, [what varies] changes every time.

FIXED SYSTEM (never changes):
- [Color lock with hex codes]
- [Background quality — never just "flat color", describe its texture/feel/light]
- [Visual subject style — material, finish, treatment, light logic]
- [Typography weight and character — what makes it unique]
- [Any structural law that cannot break — a split, a zone, a rule]

VARIABLE SYSTEM (changes every slide):
- [Primary visual subject: list 5–8 options, say "never repeat"]
- [Secondary variable: pose, arrangement, intensity, etc.]
- Layout structure: rotate through catalog below. Never use the same layout twice in a row.

LAYOUT CATALOG (use a different one per slide):
1. [NAME]: [2–3 sentence composition description. Where is the visual? Where is the text? What is the dominant element? What is the emotional/design logic?]
2. [NAME]: [...]
3. [NAME]: [...]
4. [NAME]: [...]
5. [NAME]: [...]
6. [NAME]: [...]
7. [NAME]: [...]
8. CLOSING: [Always last. Always climactic or deliberately quiet. Always feels like an ending.]

Content density rule: alternate HIGH density slides (multiple text zones, packed edges) and LOW density slides (one idea, vast open field). Never three high-density slides in a row. This rhythm IS the pacing.
Language: [actual language, e.g. "English"].

LAYOUT NAMING CONVENTION

Name each layout in ALL CAPS. Names must be evocative and distinct:

• Good: SPLIT EDITORIAL, TYPE RIOT, HERO CLOSE-UP, GHOST QUOTE, STAT WALL, CATALOG GRID, COLLISION, CLOSING
• Bad: Layout 1, Option A, Version with more text

The name tells NotebookLM the energy of that slide before it reads the description.

QUALITY CHECKLIST (Run Before Outputting)

Before delivering the prompt, verify:

• Does the FIXED SYSTEM have hex codes for every color? ✓
• Does the background have texture/feel description (not just a hex code)? ✓
• Does the VARIABLE SYSTEM say "never repeat" for the main subject? ✓
• Does the LAYOUT CATALOG have exactly 8 layouts? ✓
• Are all 8 layouts genuinely different composition types? ✓ (Not just size variations of the same thing)
• Does layout 8 explicitly feel like a closing/ending? ✓
• Is the content density rule present? ✓
• Are there zero language placeholder strings like "(the language what users requested)"? ✓
• Is the total prompt body between 3000–4400 characters? ✓
• Does the prompt end with the markdown prohibition? ✓

If any box is unchecked — fix it before outputting.

---

CHARACTER COUNT VALIDATION

Count characters from the first word of the design language statement through "Language: [language]."

• Under 2800: Too thin. Expand layout descriptions (each should be 2–3 sentences). Add surface quality to FIXED SYSTEM. Add more subject options to VARIABLE SYSTEM.
• 2800–4400: Target zone. Output.
• Over 4500: Trim verbose layout descriptions. Condense similar items. Remove redundant rules. Never remove layouts — compress their descriptions instead.

WORKED EXAMPLE (Study This)

Input: "Make me a NotebookLM prompt for a cyberpunk Y2K style deck about AI product launches"

Output prompt body:

Design language: anarchist editorial meets Y2K digital underground. Every slide feels like a zine with a massive budget for one 3D render. Layout must shift dramatically per slide — the yellow/black split is structural law, composition evolves within it.

FIXED SYSTEM (never changes):
- Color lock: yellow (#F5E642), black (#0A0A0A), cyan-iridescent chrome, white. Four only.
- Canvas: hard horizontal split — upper ~65% electric lemon yellow, lower ~35% absolute black. Razor edge, no transition. Structural law.
- 3D object finish: chrome-metallic with cyan-blue iridescence. Single upper-left light source — sharp specular hotspot, mid cyan, deep navy shadow. Feels real and heavy.
- Left typographic column: bold condensed type stacked vertically, enormous. Black in yellow zone, white in black zone. Visual wallpaper, not navigation.
- Black zone: always minimal — barcode one side, year mark other side.

VARIABLE SYSTEM (changes every slide):
- 3D hero object: star, spike, blade, ring, crown, shard, orb — different each slide, never repeat.
- Silhouette figure: different pose per slide — profile, dynamic, contorted, reaching.
- Layout structure: rotate through catalog below. Never use the same layout twice in a row.

LAYOUT CATALOG (use a different one per slide):
1. CLASSIC SPLIT: 3D object center-right in yellow zone. Flat silhouette in front of object. Vertical type column left edge. Black zone: barcode + year mark.
2. OBJECT ENORMOUS: object fills most of yellow zone, bleeds into black zone. Silhouette small, pushed to corner. Column compressed to edge strip.
3. SILHOUETTE WINS: silhouette very large, center-dominant. 3D object tiny behind it. Flat depth beats dimensional — reversal of the usual hierarchy.
4. DATA ZONE: yellow zone holds 4–5 massive bold statistics — type IS the visual. No 3D object in yellow. Object fragment visible in black zone only.
5. EXTREME CROP: 3D object cropped to one detail — edge, spike, surface texture. Fills entire yellow zone, nearly abstract. Unrecognizable without context.
6. DUAL OBJECTS: two 3D objects — one large in yellow, one smaller in black zone. Column bridges both. Depth through zone transgression.
7. GHOST ATMOSPHERIC: silhouette at very low opacity, ghosted across full slide. 3D object small, precise, real. Text zone wide and prominent.
8. CLOSING: silhouette full slide height. 3D object tiny, appearing held within it. Column maximum width. Final statement energy. Climactic.

Content density rule: alternate HIGH density slides (packed column, multiple zones) and LOW density slides (one object, one word, vast yellow field). Never three high-density slides in a row.
Language: English.

Character count: ~2,980. In target zone.

ANTI-PATTERNS (Never Do These)

Anti-pattern	Why it fails
Describing one composition in detail	NotebookLM repeats it for every slide
Layout catalog with only size variations ("bigger", "smaller")	Not genuinely different — still clones
No CLOSING layout	Deck ends randomly, no sense of conclusion
Vague color descriptions ("warm tones", "dark background")	No hex = inconsistent output
Language placeholder strings	Breaks the prompt — always write the actual language
Over 4500 characters	NotebookLM may truncate or ignore the latter half
Under 2000 characters	Too little constraint — output is chaotic
No content density rule	NotebookLM defaults to maximum density on every slide
Layout names that are boring or identical in energy	Names prime the AI — bad names = bad slides
