I attended Craig's Prompt Engineering course which was spread over 3 days and was everything I had hoped it would be and much more.

Craig took the time to explain everything clearly and in bite size portions so you did not have the feeling of being overwhelmed.

For me the actual thought of AI is a scary one and thankfully I knew who to turn to. Craig has some excellent knowledge and insight into how it works and how to use it to help.

Great courses and detailed insight into harnessing AI for businesses. Recommended.

Really great course delivered by Hartz AI. Can't wait to put everything I've learnt into practice.

Craig's Prompt Engineering course was nothing short of transformative. The 3 days were full of lightbulb moments and clarity in a way that you can only experience when sitting in the training room. What stood out was the trainer's ability to break down complex concepts into simple, practical steps that I could immediately apply to a number of areas across my organisation.

An excellent course on generate fantastic images with Midjourney AI app. The course was well paced and full of useful examples that took us from zero knowledge to enthusiastic users within 3 hours. It was also tremendously fun! I strongly recommend Harzt AI. Our trainer was excellent. To anyone running a business, large or small, you need to get your staff on this course and on the Chat GPT course.

Craig (at Hartz AI) is an excellent coach on anything and everything to do with AI. I found him to be engaging, a real expert on the topic. His courses are hands on and fun. I would highly recommend him.

We invited Craig to speak on our peopleHUB webinar last week to discuss AI and ways we can embrace it in the workplace. He provided a fantastic session which was both insightful and interesting. AI can be overwhelming, yet Craig explained it in a way that made perfect sense. Craig shared many tips and tricks for using AI, particularly ChatGPT, and how to get the best out of it.

Was a good course.

I really got a lot from the 3 day course that was run by Craig and Hartz AI, as it gave me a comprehensive explanation for how to use AI in a variety of personal and business use cases. The course taught me how to use generative AI to craft advanced prompts so that I can utilise tools such as ChatGPT in a much more effective way. I would highly recommend Craig and Hartz AI to others!
