8 Practical AI Scenarios for Everyday Use: Tools, Tutorials, and Prompts

The most common and widely used AI application is its ability to function as an encyclopedia. Gone are the days of searching through multiple sources for answers; now, AI can provide immediate responses to virtually any query. Most conversational AI models, including DeepSeek, Kimi, Doubao, and ChatGPT, excel at this. For instance, when faced with a complex Excel problem involving multi-point time card data aggregation and conditional filtering—a task that would typically require extensive Excel expertise or extensive online searching—AI provided a direct solution. This capability extends to follow-up questions, allowing users to iterate with the AI until the correct answer is obtained. This makes AI an invaluable tool for quick information retrieval and problem-solving in everyday situations.

Article polishing is a highly utilized AI application, particularly for those who prefer to create content themselves rather than relying on AI for initial generation. AI-generated articles often fall short of personal standards, sometimes containing factual errors (AI hallucinations) that require time-consuming corrections. Furthermore, over-reliance on AI for writing can potentially lead to a decline in one's own cognitive abilities, akin to neglecting physical exercise. Therefore, the preferred approach is to draft content first and then leverage AI for refinement. A suggested prompt for article polishing includes: 'Please polish the following text, ensuring the core meaning and style are preserved. Correct all grammatical errors and typos, optimize sentence structure for fluency, enhance word choice for accuracy and vividness, and appropriately incorporate metaphors or rhetorical devices for clearer descriptions. Do not add new content or viewpoints, and maintain the original tone and emotional color. Preserve professional terminology and the paragraph structure. Provide the complete polished text without explanation of changes.'

Code programming is a transformative AI application, acting as a powerful tool for both seasoned programmers and individuals with no coding background. For non-programmers, AI can demystify coding challenges. For example, when needing to process Excel files with Python's pandas library for data analysis, AI can generate complete code snippets, including data reading, monthly aggregation, and visualization with charts, even accounting for details like Chinese font display and data formatting. For simpler programming tasks, AI can also assist. A friend's mother, a primary school teacher, used AI to generate a batch script for renaming hundreds of student assignment files, significantly simplifying her workload. Tools like Trae, developed by ByteDance and powered by DeepSeek, are readily available for addressing straightforward coding requirements.

Learning assistance is an invaluable AI application for students and lifelong learners. For a high school student struggling with a geometry proof, AI tools like Claude provided not only the complete proof process but also detailed explanations of each step, the underlying principles, and even comparative analyses of different solutions. Students can ask follow-up questions, and the AI patiently explains concepts in simpler terms until understanding is achieved. For personal learning, AI can design customized study plans. For example, when exploring quantum computing, a complex field, ChatGPT helped create a structured learning path, starting from basic quantum mechanics and progressing to quantum algorithms. AI can also be used to test comprehension by posing questions and identifying areas of misunderstanding. Effective prompt techniques include clearly stating your knowledge level, requesting multi-angle explanations, designing learning paths, and using AI for knowledge verification.

While AI offers immense benefits, certain scenarios demand caution and should not be solely reliant on AI. Firstly, **Medical Consultation** is a critical area. AI can offer basic health information, but for diagnosis and treatment, consulting a professional doctor is paramount. AI may provide inaccurate information or cause undue anxiety by listing multiple potential conditions. Secondly, **Emotional Companionship** is another area where AI falls short. While AI chatbots can offer temporary comfort, they lack genuine empathy and cannot replace professional psychological counseling. Over-reliance can hinder real-world social interaction skills. Lastly, **Financial Advice** requires careful consideration. AI can provide market data and basic financial knowledge, but investment decisions should not be based solely on AI recommendations. AI analyses may not account for individual risk tolerance, investment horizons, or overall financial situations, potentially leading to significant losses. For these sensitive areas, AI should be viewed as a supplementary tool, with professional human judgment and expertise remaining indispensable.
