Do you know an AI firm that can help build a machine learning tool or Photoshop script to automate the graphic design process in my business?

Sure this is easy.

You'll require a massive amount of cash. If you have to ask "how much cash", then you won't explore AI.

Once you've determined your AI tech, then you'll go through a multi-year process of Knowledge Acquisition, where you extract knowledge of your entire manual process from every person engaged in the current manual process.

Begin training your neural nets.

After a few years... to a decade... you'll have a Poe'esque (Ala "Altered Carbon") level AI to do your graphic design for you... auto-magically...

I remember going through this process at MCI Telecommunications years ago.

Fairly straight forward.

Just took $1,000,000s of hard cash over a 10+ year period to convert their switching tech to AI'esque style logic.

For your need, you can use these AI technologies in machine learning:
1. TensorFlow
Initially released in 2015, TensorFlow is an open source machine learning framework that is easy to use and deploy across a variety of platforms. TensorFlow is available in Python, C++, Haskell, Java, Go, Rust, and most recently, JavaScript. The framework allows you to develop neural networks using flowgraphs.

2. Keras
Initially released in 2015, Keras is an open source software library designed to simplify the creation of deep learning models. It is written in Python and can be deployed on top of other AI technologies such as TensorFlow, Microsoft Cognitive Toolkit, and Theano.

3. Programming and development
This traditional framework is written in Python and features several machine learning models including classification, regression, clustering, and dimensionality reduction.

4. Microsoft Cognitive Toolkit
Microsoft says that the open source framework is capable of «training deep learning algorithms to function like the human brain».

5. Caffe
Initially released in 2017, Caffe is a machine learning framework that focuses on expressiveness, speed, and modularity. The open source framework is written in C++ and comes with a Python interface.

6. Torch
Initially released in 2002, Torch is a machine learning library that offers a wide array of algorithms for deep learning. Some of Torch's key features include N-dimensional arrays, linear algebra routines, numeric optimization routines, efficient GPU support, and support for iOS and Android platforms. Initially released in 2010, Accord. NET is a machine learning framework entirely written in C#.

This is an interesting but open ended question. It would depend on what kind of graphic designs the AI has to automate.

I am interested to learn more!
