ChatGPT usage rules
Before you get started, here's what you need to know to use ChatGPT safely.
🚫 What ChatGPT refuses to do
ChatGPT is not an “all-terrain” tool. Here are its main limitations:
Prohibited content:
- Hate or discriminatory language
- Harassment or threats
- Explicit sexual content involving minors
- Instructions for illegal activities
- Creation of malware or viruses
Good to know: If you're testing these limits out of curiosity, ChatGPT will politely explain why it can't respond, without blocking your account.
🔒 Protect your personal data
| 🔒 Personal Data | ✅ OK to Share | ❌ To Avoid |
|---|---|---|
| Industry Sector | I work in retail | — |
| Employer (General) | I work at Carrefour Roissy | — |
| Project Budget | I have a budget of X€ for this project | — |
| Geographic Location | I live in the Paris region | — |
| Business Type | My company operates B2B | — |
| Salary | — | My salary is X€ |
| Exact Address | — | My address is 15 rue... |
| Client List | — | Our clients are: [full list] |
Practical tip: Replace real names with codes. Instead of “My colleague Pierre”, say “My colleague P.” or “a marketing colleague.”
Optimize your questions for better answers
❌ Vague question:“How do I do marketing?”
✅ Specific question:“How do I create a Facebook Ads campaign for my hair salon in Lyon with a budget of 300€/month, targeting women aged 25-45?”
ChatGPT
ChatGPT understands ENglish perfectly, but some specificities to know:
- Sometimes “translated” answers: Some expressions may sound English
- Cultural references: Mostly American, adapt your examples
- You can ask for: “Answer in fluent ENglish” or “Use French expressions”
Difficulties with using ChatGPT
The main challenge: to distinguish what is true from what is false
ChatGPT may be lying to you... without knowing it!
AI sometimes generates “hallucinations” - information that seems correct but is invented.
Concrete examples of common mistakes:
| ❌ Information Type | ⚠️ Example of Error |
|---|---|
| Exact Dates | “The GDPR came into effect on May 15, 2018” (actual date: May 25, 2018) |
| Statistics | “73% of French people use Instagram” (actual figure: 52.8% in 2026) |
| Attributed Quotes | Attributing “Creativity is intelligence having fun” to Albert Einstein — a widely circulated apocryphal quote |
| Recent Events | “Euro 2022 took place from June 10 to July 10 in Germany” (in reality, Euro 2024 was held from June 14 to July 14, 2024) |
How to verify information
Simple 3-step method:
- Quick Google search for important facts
- Crossing with 2-3 reliable sources (official sites, recognized press)
- Common sense: does the information seem coherent to you?
Golden rule: The more important the information is to you (work, health, finances), the more you need to verify it.

⚠️ The hidden biases of AI
ChatGPT is not neutral. Her answers may reflect:
- Geographic biases : Mainstream Western/American perspective
- Time biases : Information dated according to his training period
- Professional biases : Advice oriented to “white collar” or “tertiary sector”
How to protect yourself from it? Add in your prompts: “Adapt your response to the French context” or “Give various examples according to different profiles”
The permanent evolution of the tool
👍 Positive points
- Steady improvements in accuracy
- New features added frequently
- Correction of identified bugs
👎 Points of attention
- Your experience may change from week to week
- Some answers may become out of date
- Need to adapt to updates
Practical advice: If a feature doesn't work as it used to, it may be due to an update. Check out OpenAI news to stay up to date.
Use cases to avoid absolutely
For professionals:
- Drafting contracts without legal validation
- Medical diagnoses or health advice

For individuals:
- Personalized legal advice
