## What is Napkin AI Visual Gen Lab?

Napkin AI Visual Gen Lab helps business users turn written prompts into professional visuals for charts, diagrams, infographics, illustrations, org charts, and auto-selected formats.

VISUAL TYPES
Choose the format that fits the message, then refine the result with style presets and output controls.
• Chart, Diagram, Infographic, Illustration, Org Chart, and Auto modes
• Style presets: Minimal, Corporate, Bold, Outlined, and Pastel
• Output formats: Square, Portrait, Landscape, or Auto
• Background options: transparent or opaque

GENERATION SPACE
Build each visual from a prompt, watch generation progress, and keep working from the same result screen.
• Enter a prompt up to 1000 characters
• Generate a visual from the selected type and settings
• Stay on the generation screen until the result appears or fails
• Open a result, regenerate, enhance, share, or download from one place

HISTORY AND REVISITS
Past visuals stay in History with previews and truncated prompts, so earlier work is easy to find and revisit.
• Review previous generations with preview thumbnails
• Read the saved prompt snippet beside each result
• Open older outputs for another pass or a new version

PROMPT ENHANCER
A separate premium feature rewrites prompt copy before generation, giving you a stronger starting point for business visuals.
