My Dream for AI

I am thrilled about the endless opportunities that AI brings. But, at the same time, I can’t help but hope for a world where AI is used for good, and not just to dominate the web with generated content. My dream is to see AI being utilized to enhance our productivity, empower new voices to be heard (because let’s be real, not everyone is a native speaker or may have challenges when it comes to writing), and help us save time on tedious tasks so we can spend more precious moments with our loved ones and the world around us.

I will always advocate this, and I hope you do too 💕

I do not code enough to make Generative AI work in Wordpress without AI plugins. This one works wonders for me as I now can focus on running my business instead of burying myself in coding.

I came across AI Engine as part of my initial research into LLM and AI Engine not only make the learning curve less steep, it also delivers amazing value and save me hours of creating my own interface. Within a week I deploy a number of useful chatbots both for my experiments and real client use case.
