Overview

Nodetool is a no-code development environment for Artificial Intelligence, enabling the simple and intuitive creation of powerful AI workflows and their integration into existing applications. Utilizing a node-based user interface, users can construct complex, multimodal applications without any programming knowledge. Nodetool facilitates the seamless integration of state-of-the-art AI models, allowing the generation and editing of multimedia content such as images, texts, audio, and video within a single workflow.

Nodetool opens up a creative and playful access to current technologies, supporting both beginners and experienced developers in the fields of content creation, data analysis, and automation. It enables a broad audience to benefit from the advantages of artificial intelligence by visualizing workflows and simplifying complex installation requirements, making AI application development accessible to novices and seasoned users alike.

Key Features

• No-Code AI Development: Create AI workflows without deep programming knowledge.
• Model Agnostic: Easily integrate new nodes and state-of-the-art AI models from OpenAI, Anthropic, Replicate, HuggingFace, ComfyUI, Llama, Mistral, and more.
• Multimedia Content Handling: Generate and edit images, texts, audio, and video in one workflow.
• Open and Transparent: Aims to make the execution and training of AI models more transparent and accessible.
• Asset management: Manage and organize your assets (images, videos, audio files) within the application

Installation

pip install nodetool

Usage

To get started with Nodetool:

nodetool setup

Execution

• Nodetool Editor: Install the Nodetool Editor for an intuitive, graphical interface to design and manage workflows.
• Command Line Execution: Alternatively, execute workflows directly from the command line for automation and scripting purposes.

Implementing Nodes

New nodes can be added by subclassing BaseNode.

Node properties are defined using class fields with type annotations.

The node operation is defined in the process method, which takes a context object, allowing I/O amongst other operations.

class MyNode(BaseNode):
    a: str = ""
    b: str = ""

    async def process(self, context: ProcessingContext) -> str:
      return self.a + self.b

Setup Files

The following files are used for storing settings and secrets:

• settings.yaml: Stores general settings
• secrets.yaml: Stores secret values (API keys, tokens, etc.)

The location of these files depends on the operating system:

• Linux/macOS: ~/.config/nodetool/
• Windows: %APPDATA%\nodetool\

If the files don't exist, default values will be used.
