## Pricing Philosophy

Greneta operates a freemium model:
- Free tier is permanently available — no credit card required for basic use
- Paid tiers unlock higher usage, batch features, and API access
- No per-model download fees for subscribers (unlimited within plan limits)
- One-time purchases available for non-subscribers on select premium models

## Use Case Examples

### Game Development
A mobile game studio can browse the Collection for optimized character and prop assets, download in glTF format, and import directly into Unity or Unreal. The pre-optimized polygon counts and PBR textures reduce asset integration time from days to minutes.

### XR / AR Development
An AR app developer building for Apple Vision Pro can use the Workspace-3D to upload existing 3D assets, apply compression targeting under 1MB per model, and download optimized GLB files ready for visionOS spatial computing environments.

### Web 3D Experiences
A web developer building a product configurator can use Collection models or optimize their own assets via the API, then embed them using Three.js or React Three Fiber with fast load times thanks to compressed file sizes.

### 3D Asset Pipeline Automation
An enterprise with a large 3D asset library can integrate the Greneta API into their CI/CD pipeline to automatically compress and validate 3D assets before deployment.

## Competitive Differentiation

- **AI-native compression**: Unlike manual LOD tools, Greneta's AI preserves semantic features (face geometry, distinctive silhouettes) during polygon reduction
- **End-to-end platform**: Marketplace + Generator + Optimizer in one platform
- **Web-first**: No desktop software installation required; everything runs in the browser
- **Format-agnostic**: Accepts all major 3D formats, outputs universally compatible glTF
- **Real-time preview**: Evaluate model quality before downloading with an interactive 3D viewer

## Glossary

- **glTF / GLB**: GL Transmission Format — the "JPEG of 3D" — an open standard for 3D assets optimized for web delivery
- **PBR**: Physically-Based Rendering — a shading model that simulates real-world light interaction for photorealistic appearance
- **LOD**: Level of Detail — technique of using lower-polygon versions of models at greater viewing distances to save GPU resources
- **Polygon**: The basic unit of 3D geometry; lower polygon counts = smaller files and faster rendering
- **XR**: Extended Reality — umbrella term for AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality)

A: Greneta uses proprietary AI-powered algorithms to reduce 3D model file sizes by up to 95% while maintaining visual quality, enabling smooth real-time rendering in web browsers, mobile apps, and XR devices. The AI identifies semantically important geometry to preserve while aggressively simplifying less critical areas.

**Q: Which 3D file formats does Greneta support?**
A: Greneta supports glTF/GLB, FBX, OBJ, STL, COLLADA, and other major 3D formats as input. Output files are in glTF 2.0/GLB format, optimized for Unreal Engine, Unity, WebGL, Three.js, and XR platforms.

**Q: Is Greneta free to use?**
A: Yes, Greneta offers a permanently free tier with no credit card required. Paid subscription plans are available for professionals and enterprises that need higher usage limits, batch processing, and API access.

**Q: Can I generate 3D models from text with Greneta?**
A: Yes. Greneta's AI 3D Generator creates 3D models from text prompts or reference images, making it possible to quickly prototype 3D assets without manual modeling skills or software.

**Q: What game engines are supported?**
A: Greneta's optimized models work seamlessly with Unreal Engine 5, Unity, Godot, and web-based engines using WebGL, Three.js, React Three Fiber, and Babylon.js. Models are delivered in glTF 2.0 format for maximum compatibility.

**Q: Can Greneta handle batch processing?**
A: Yes. The 3D Workspace supports batch upload and compression, allowing studios to process large asset libraries efficiently. Enterprise plans include API access for automated batch workflows.

**Q: Is there an API available?**
A: Yes. Enterprise plans include REST API access for integrating Greneta's optimization pipeline into custom workflows, CI/CD pipelines, and production asset management systems.

**Q: How does Greneta compare to Sketchfab?**
A: Sketchfab is primarily a 3D model viewer and marketplace. Greneta additionally provides AI-powered compression and optimization tools, an AI model generator, and a workspace for processing your own assets — making it a more complete production pipeline rather than just a marketplace.

**Q: Does Greneta work for Apple Vision Pro?**
A: Yes. Greneta's optimized GLB models are compatible with visionOS and can be used in RealityKit or via WebXR in Safari on Vision Pro.

**Q: What is the maximum compression ratio?**
A: Greneta has demonstrated up to 95% file size reduction on complex models while maintaining commercially acceptable visual quality. Actual compression depends on model complexity, texture density, and target platform requirements.
