I’m Michael
I’m an entrepreneur who has been deeply involved in the cultural industry for over 10 years. As a small- and medium-sized business owner, I have to carry everything myself—
taking orders, replying to messages, publishing content, organizing data…
I hand repetitive work over to AI, and what I’m sharing today are core AI concepts I only understood after stumbling through a lot of pitfalls.
Do you ever feel like this:
- Others talk about GPT and Claude, and you’re completely confused
- You want AI to help you work, but you don’t even understand the basic concepts
- Online tutorials are either too simple or too technical, and you still don’t know how to use it afterward
- You’re worried about being left behind in the AI era, but don’t know where to start
I really understand this anxiety.
Before 2023, my understanding of AI was basically limited to “robots in sci-fi movies.” It wasn’t until ChatGPT went viral and all my business friends started talking about AI that I realized: not understanding AI might really mean being left behind by the times.
In this article, I’ll use the simplest language to fully explain those confusing AI concepts in one go. After reading it, you’ll know: what AI actually is, what it can do for you, and how to start using it.
What is AI? Explained in one sentence
AI (Artificial Intelligence) = a computer program that can imitate human thinking and learning
Don’t be intimidated by the words “artificial intelligence.” Simply put, AI is a very smart tool that can understand what you say, help you think through problems, and do work that requires “mental effort.”
It’s like how your phone evolved from “only being able to make calls” to “being able to browse the internet, take photos, and navigate,” computers have also evolved from “only being able to calculate” to “being able to chat, write articles, and generate images.”
Why has AI suddenly become so popular now?
Because of a technological breakthrough.
In the past, AI was like a “rote-learning top student” that only followed programmed instructions. Now, AI is like a “gifted thinker” who can learn from massive amounts of data and flexibly handle new problems.
Several core concepts you must know
1. Large Language Model (LLM)
Simple understanding: an AI that has read almost all the world’s books and can chat normally with you
- AI trained on massive text data (books, webpages, academic papers)
- Can understand human language and generate human language
- Like a knowledgeable friend who can talk about almost anything
Representative products:
- GPT (from OpenAI, the technology behind ChatGPT)
- Claude (from Anthropic, especially good at handling long texts)
2. Prompt
Simple understanding: the way you talk to AI
Why it matters:
The same question, phrased differently, can lead to drastically different answer quality from AI
Example:
- Bad prompt: “Write me some copy”
- Good prompt: “I sell handmade soap. My target customers are women aged 25–35 who care about natural skincare. Please write a 150-word WeChat Moments post highlighting natural ingredients, with a warm tone and no overly commercial language.”
3. Training data
Simple understanding: the “textbook” of AI
- Massive text, images, and code used for AI training
- Like humans learning from books, AI learns by “reading” data
- Data quality determines the upper limit of AI capability
Knowledge cutoff time: AI only knows information up to the time it was trained. It does not know what happened afterward. For example, GPT-4’s knowledge cutoff is April 2023. If you ask about events in 2024, it cannot answer.
4. Token
Simple understanding: the smallest unit AI uses to process text, which affects cost
- 1 English word ≈ 1–2 tokens
- More tokens = higher cost (if using paid services)
Why this matters:
Many AI services charge based on tokens. Understanding this helps you control costs.
What can AI do?
Text processing
- Writing copy, emails, summaries
- Translation, polishing, rewriting
- Extracting key points, organizing information
Creative generation
- Naming products, creating headlines, storytelling
- Planning events, designing solutions
- Brainstorming and idea generation
Analysis & decision-making
- Analyzing data and summarizing trends
- Comparing options and giving suggestions
- Risk assessment and problem diagnosis
Learning assistance
- Explaining concepts and answering questions
- Creating study plans
- Practicing conversations (e.g., English speaking practice)
Real examples (things I actually use)
- Too many customer inquiries? Let AI draft reply templates
- Can’t write product descriptions? Let AI turn selling points into engaging copy
- Can’t finish competitor analysis? Let AI summarize competitors’ strengths and weaknesses
- Don’t want to write meeting notes? Let AI extract key points from recordings
Common AI product categories

How beginners should start using AI
Step 1: Choose an entry-level product
Free options:
ChatGPT free version
Step 2: Learn how to ask questions
Formula: Role + Task + Requirements + Example
Example:
You are a senior copywriter (role) Help me write a WeChat Moments post selling handmade soap (task) Target customers are mothers; emphasize natural and additive-free ingredients; 150 words or less; friendly tone (requirements) Reference style: “Since using this handmade soap, my baby’s skin has become so much smoother~” (example)
Step 3: Start with small tasks
- Ask AI to write a thank-you email
- Ask AI to summarize a long article
- Ask AI to suggest product names
- Ask AI to analyze pros and cons of a problem
Step 4: Build your own prompt library
Collect useful prompts so you can reuse them later. Just like collecting writing templates.
Things to keep in mind when using AI
✅ What to trust
- AI is strong at information organization, copywriting, and brainstorming
- AI can greatly improve work efficiency
- AI will continue to evolve and become smarter
❌ What not to trust
- AI is 100% accurate (it may hallucinate or make things up)
- AI can completely replace human thinking
- AI knows the latest events (it has a knowledge cutoff)
🔒 Privacy & security
- Do not share confidential information with AI
- Be careful when using sensitive business data
- Choose trustworthy AI providers
💡 Correct mindset
- AI is a tool, not magic
- You need practice to use it well
- It’s human–AI collaboration, not replacement
Future trends of AI
Increasing capability
- From only chatting → to seeing images, listening to audio, generating video
- From answering questions → to proactively completing tasks
- From single functions → to comprehensive abilities
Becoming easier to use
- No need to learn complex technical skills
- Voice interaction will become more common
- Integrated into various software and devices
Lower costs
- More free products available
- Paid products becoming cheaper
- Higher computing efficiency
Meaning for individuals
- People who can use AI will dramatically improve efficiency
- People who cannot may be replaced or left behind
- This is not exaggeration—it is already happening
Final thoughts
AI is not here to replace you, but to amplify your abilities. Just like the internet didn’t eliminate physical stores—it helped those who used it grow bigger.
AI is the same. The key is to learn and embrace it actively. No need to fear, no need to be anxious.
AI is still relatively “dumb” and far from sci-fi intelligence. But it already saves time and improves efficiency—and that alone is enough.
Starting today, pick an AI tool, ask it one question, and begin your AI journey. Trust me—you’ll thank yourself one month later.
