- Download NodeTool — install for macOS, Windows, or Linux.
- Choose your AI models — install local models like Flux/SDXL, or use cloud services.
- Try a template workflow — explore examples, press Run, watch results stream.
- Experiment and customize — change inputs, connect nodes differently, make it yours.
- Share your workflow — turn it into a simple app others can use.

Local-first or cloud-augmented
Local-only mode
All workflows, assets, and models run on your machine for maximum privacy and control.
- Use MLX, llama.cpp, Whisper, and Flux locally
- Store assets on disk or your own storage
- Work offline once models are downloaded
Cloud-augmented mode
Mix local AI with cloud services for flexibility. Use the best tool for each task.
- Add API keys for OpenAI, Anthropic, Replicate
- Access cutting-edge models on demand
- Deploy workflows to cloud infrastructure
📱 Personal AI Stack
Access self-hosted AI infrastructure from mobile devices.
NodeTool's mobile app connects to your own NodeTool server. Run workflows remotely, accessing models and data on hardware you control.

Deployment Options
🏠 Local Stack
Connect via VPN to a home server. All processing on your hardware. Data stays on your network.
[Mobile] → [VPN] → [Home Server] → [Local LLMs + Data]
☁️ NodeTool Cloud
Managed infrastructure. No hardware setup. Workflows sync across devices.
[Mobile] → [NodeTool Cloud] → [Managed LLMs + Storage]
🏢 Private Cloud
Deploy to your organization's VPC. Supports compliance requirements and multi-user access.
[Mobile] → [VPN] → [VPC] → [Self-Hosted NodeTool]
🌐 Hybrid Stack
Local processing for sensitive data, cloud APIs for additional models.
[Mobile] → [Local Server] → [Local LLMs + Cloud APIs]
Capabilities
- Personal AI Assistant — Chat with an AI that accesses your documents and knowledge base.
- Mobile AI Workspace — Generate images, audio, and video from your phone using local models.
- Private Knowledge Base — Index and query your documents with RAG.
