Let me reveal the secret of Polichinelle.

There is NO real and true AI in the human world, yet. AI must be proactive and interactive and exhibit causal (common sense) knowledge and reasoning, as well as the world/data machine understanding, at least.
But there are fake AIs and false ML, like Google’s Bard vs. ChatGPT.

ChatGPT uses NLP to create humanlike conversational dialogue trained with RL via human feedback and reward models ranking the best responses, responding to questions and compose various written content, including articles, social media posts, essays, code, emails, product descriptions, summaries of transcripts, meetings and podcasts, simple explanations of complex topics, law briefs, translations, jokes or memes, blog posts.
Bard simulates human conversations with NLP and ML by drawing responses from the internet using the LLMs, LaMDA and PaLM.
Here are some best fake AI/ML tools for generating text, speech, video, image, notes, apps, etc.
1. Adobe Firefly: Image and text effect generation
2. NVIDIA Broadcast: AI-enhanced voice and video
3. Notion AI: More efficient notes and docs
4. Canva AI: Image Generator, Text Generator, Magic Design, and Photo Editor
5. GPT-4 (Plugins)
6. Eleven Labs: AI Text to Speech
7. D-ID: AI Generated Video Creation animates images from text or audio
8. Midjourney/Leonardo AI: Image generation
9. AutoGPT / AgentGPT
10. GPT
