The Pipeline Builder
A visual canvas for building AI workflows. Drag, connect, and run — right in your browser.
Block-Based
Snap together prompt, model, response, and vision blocks to create multi-step AI pipelines.
Any Model
Works with Ollama, OpenAI, Anthropic, Groq, and any OpenAI-compatible endpoint.
Browser-Based
No installation needed. Open the web app and start building immediately.
ToolPiper for macOS
A menu bar companion that bundles local AI inference. One click to download models, run them on-device, and read unified logs.
Curated Model Library
Browse and install models with one click. LLMs, vision models, and TTS engines — all pre-configured.
Bundled Inference
llama.cpp, Apple Intelligence, speech-to-text, and text-to-speech — all running on your hardware.
Unified Logs
Every HTTP request, response, and error from all backends in one searchable stream.
Zero Config
Download a model, launch, and go. ToolPiper handles inference, model management, and server lifecycle.
Requires macOS 26 or later

How It Works
Three steps to your first AI pipeline.
Install ToolPiper
Download the macOS menu bar app. Pick a model and it downloads — ready to run on your hardware.
Open the Web App
Launch the pipeline builder in your browser. Add blocks, pick a model, and wire them together.
Run Your Pipeline
Hit run. Your prompts flow through connected models — streaming responses in real time.
Your Data Stays on Your Mac
ModelPiper runs entirely on your machine. Your prompts, responses, and workflows never leave your device — unless you choose a cloud provider.
