Practical Usage Tips
1. Ask One Thing at a Time
At first, you might want to ask "Do this, do that" all at once...
One clear question gets much better answers.
Bad example:
I want to study Python, how should I start? Also recommend books. Tell me about online courses too.
Good example:
Organize a learning roadmap for Python beginners in 3 stages.
2. Ask Again If You Don't Like the Answer
AI makes mistakes sometimes! If the response seems off:
- "Explain it again"
- "Say it more simply"
- "Explain with examples"
3. Continue the Conversation
AI remembers previous conversations!
Question 1: "Tell me how to make a calculator in Python"
Question 2: "Add subtraction functionality here too"
Question 3: "Add code comments too"
Continuing the conversation like this gets you closer to what you want.
4. Be Specific in Your Requests
Specific questions are much better than vague ones.
Vague question:
Write a resume
Specific question:
I'm writing a resume for a junior marketing position. Experience is 6 months as an intern, and I've run SNS marketing campaigns. Write a cover letter draft.
Free vs PaidโWhat's the Difference?
All three AI can be used plenty for free!
What the Free Versions Can Do
- โ Unlimited text conversations (some have usage limits)
- โ Basic writing, translation, summarization
- โ Simple code writing
- โ Learning help
Additional Features in Paid Versions (Just for reference)
- Faster response speed
- Access to latest AI models (GPT-4, Claude 3 Opus, etc.)
- Plugins and extensions
- Priority support
Conclusion: Free versions are sufficient for regular users! Paid is needed for heavy work users.
Important Warnings
1. Never Enter Personal Information
Never input sensitive information like social security numbers, account numbers, or passwords into AI chats!
Conversation content may be used for AI training.
2. Don't Trust It 100%
AI sometimes makes plausible lies (hallucination phenomenon).
Especially for medical, legal, financial questions, consult with professionals.
3. Watch Out for Copyright
When using AI-generated text or images commercially, check each service's terms of use!
