GauGAN

GauGAN is an NVIDIA tool that converts simple sketches and text descriptions into photorealistic images, primarily focused on landscapes. It’s based on GAN technology and is designed to help quickly prototype scenes from rough layouts.

Key capabilities

• Turn rough sketches into realistic landscape scenes
• Generate images from text prompts (GauGAN2)
• Work with 15 segmented object types (e.g., grass, mountains, water)
• Output images up to 512×512 px
• Export results as PNG and in a ZIP archive
• Support multi-layer sketches and real-time generation
• Integrates with NVIDIA Canvas

How to use

GauGAN is available as a web app at gaugan.org and as NVIDIA Canvas for Windows 10 on systems with RTX GPUs.

• Open the GauGAN site and accept the terms
• Choose a drawing tool (brush/pencil) and sketch the scene layout
• Assign object types (such as sky, grass, water)
• Add an optional text prompt
• Run generation and save the result

Web access is free. Using NVIDIA Canvas requires an NVIDIA RTX graphics card.
