Always Verify and Cite: It is critical to check AI-generated summaries against the original source for accuracy and nuance. AI can make mistakes or miss context. Tools like Liminary make this easier by including source citations automatically.
Synthesize in Your Own Words: To ensure genuine learning, summaries and insights should be rewritten in one's own voice. This act of processing information is where true understanding occurs.
Check Academic Integrity Policies: Students should always be aware of their institution's rules on using artificial intelligence tools for student study and disclose AI assistance when required.
