⚠️ Academic Integrity Warning
🚨 Use AI Responsibly
AI writing tools are powerful study aids, but they are not a replacement for your own work. Before using any AI tool for school assignments, keep these principles in mind:
- Know your school's policy: Most universities have clear rules on AI use. Some ban it entirely; others allow it with disclosure. Check your syllabus and student handbook.
- Never submit AI-generated text as your own: Passing off AI writing as original work is plagiarism and can result in failing grades or expulsion.
- Use AI for learning, not output: Treat AI like a tutor — ask it to explain concepts, critique your drafts, or suggest improvements. Then write the final version yourself.
- Always verify facts: AI can hallucinate sources, dates, and statistics. Every claim must be checked against reliable sources.
- Cite AI use when required: If your instructor allows AI assistance, disclose how you used it (e.g., "AI was used for brainstorming and grammar checking").
- Beware of AI detectors: Many schools use AI detection tools. Even "humanized" AI text can be flagged. The safest approach is to use AI as a learning aid, not a content generator.
Bottom line: AI can make you a better, faster writer — but only if you stay in the driver's seat. Use it to learn, brainstorm, and polish. Don't let it do the thinking for you.
