ChatGPT Prompt Templates 100 Collection - Complete Guide by Task

Introduction: The Key to Getting the Most Out of ChatGPT Lies in Prompts

Since its launch in late 2022, ChatGPT has attracted explosive interest worldwide and has established itself as a core productivity tool by 2026. Yet while using the same ChatGPT, some people get amazing results while others are disappointed by underwhelming responses. The difference comes down to the prompt -- the quality of the questions and instructions you give the AI.

The term "prompt engineering" has emerged to describe a specialized skill of asking AI the right questions. A single well-designed prompt can reduce hours of work to minutes and produce expert-level results. Conversely, vague and unstructured prompts will only generate vague and useless answers.

In this article, we have compiled 100 ChatGPT prompts across 5 fields -- Work, Marketing, Development, Learning, and Creativity -- that you can copy and use immediately in practice. Each prompt is provided with specific context, so you can use them right away by simply modifying the content within the brackets ([]). At the end, we also introduce 5 key principles for effective prompt writing, so use this guide to take your ChatGPT skills to the next level.

Conclusion: 5 Key Principles of Effective Prompt Writing

We have explored 100 prompts across the fields of work, marketing, development, learning, and creativity. Analyzing the commonalities among these prompts reveals that 5 key principles underpin effective prompt writing.

First, assign a Role. By giving ChatGPT a clear role such as "You are a marketing expert with 10 years of experience," you can elicit responses from a domain expert's perspective. Role assignment is the simplest yet most powerful technique for dramatically improving the depth and expertise of responses.

Second, provide sufficient Context. AI doesn't know your situation. The more specific context you provide -- background information, target audience, purpose, constraints -- the higher the probability of getting results that meet your expectations. "Write a good blog post" will never produce results as good as "Write a 2000-word SEO-optimized blog post targeting office workers in their 30s."

Third, specify the output Format. By concretely specifying the desired output format -- tables, lists, paragraphs, etc. -- you can obtain results that can be used immediately without post-processing. This is especially effective when there's a predetermined template for reports or proposals: include that structure directly in your prompt.

Fourth, include Examples. By saying "Write it in this style" along with a reference example, AI can accurately grasp the desired tone and style. This technique, called few-shot prompting, is particularly useful when you need to repeatedly generate consistent-quality outputs.

Fifth, Iterate and improve. Rather than expecting perfect results on the first try, it's more realistic to refine based on initial results with follow-up prompts like "Make it more concise," "Add specific numbers," or "Make the tone more casual." Since ChatGPT remembers the conversation context, the most efficient strategy is to continue the conversation and gradually increase quality.

These 100 prompts are just a starting point. Modify and combine them to suit your work and situation, and build your own prompt library. The key to using ChatGPT not just as a simple question-and-answer tool but as a true work partner ultimately depends on how specific and structured your prompts are.
