Modly 3D is a local-first AI application that generates 3D models from images using open-source reconstruction models running entirely on the user’s GPU. It is designed as a privacy-focused alternative to cloud-based 3D generation tools, with all processing happening offline and no data uploaded to external servers.

The core workflow is simple: users import a photo, the app automatically removes the background, and a neural reconstruction model generates a 3D mesh directly on-device. The resulting model can be previewed and exported in common formats such as GLB, OBJ, STL, and PLY for use in game engines, 3D printing, and design tools.

Modly is built around local execution on GPU hardware, meaning it does not rely on cloud APIs, credits, or accounts. This makes it fully offline-capable once installed and emphasizes privacy, speed, and unlimited usage.

The system supports multiple open-source AI models for 3D generation, including fast lightweight models for prototyping and higher-quality research-grade models for more detailed geometry. It is designed to be extensible, allowing new models to be integrated over time.

Modly is aimed at creators across different domains including game developers, 3D artists, product designers, and 3D printing enthusiasts. It allows rapid conversion of real-world or concept images into editable 3D assets, reducing dependency on manual modeling or paid cloud services.

The project is open source and developed by Lightning Pixel, with a focus on making advanced 3D reconstruction accessible locally without subscription-based constraints.

Key features include:

• Image-to-3D model generation running locally on GPU
• Fully offline processing (no cloud uploads or accounts)
• Export formats: GLB, OBJ, STL, PLY
• Open-source and extensible architecture
• Multiple AI reconstruction models (fast + high-quality options)
• Automatic background removal and preprocessing
• Built-in 3D model viewer
• Optimized for creators, game devs, and 3D printing workflows

Common use cases include:

• Creating game-ready 3D assets from images
• Generating STL models for 3D printing
• Rapid prototyping for product and industrial design
• Producing base meshes for Blender or sculpting workflows
• Offline AI experimentation with 3D reconstruction models

Modly 3D is developed by Lightning Pixel, focusing on local-first AI tooling for 3D generation and open-source creative infrastructure.
