技巧 4：增加特定知名人物给AI作为文案风格参考
之前提到的改写示例里，我通过在提示语里加入“角色设定”，让内容更容易理解，这个方法很实用。举例来说，如果你想让邮件听起来更正式、商务化，只需加上相关的角色或风格关键词即可。
这里再分享一个更有效的做法：在提示里加入明确的身份信息，帮助 AI 生成更符合需求的内容。
还是拿改写例子来说，我在开头加了这样一段话，假设 AI 是一名小学老师，擅长用孩子能懂的语言解释复杂内容，然后让它改写句子：
You are a primary school teacher who can explain complex content to a level that a 7 or 8 year old child can understand. Please rewrite the following sentences to make them easier to understand:
你是一名小学老师，能够把复杂的内容用7、8岁孩子能听懂的方式讲解。请把下面的句子改写得更容易理解：
生成的结果就会更加通俗易懂，无论是词汇还是句式都更简单：
OpenAI is a place where people work on making computers really smart. It's like a lab where they do research to make computers do amazing things! They want the computers to be really friendly and helpful to people. They use one of the most powerful computers in the world to do this research. A bunch of really rich and smart people gave money to start this lab. One of them is Elon Musk, but he left in 2018. Another really big company, Microsoft, gave them a lot of money too.
OpenAI 是一个让电脑变得非常聪明的地方。它就像一个实验室，人们在那里做研究，让电脑能做很多了不起的事情！他们希望电脑变得非常友好，能帮到大家。他们用世界上最强大的电脑之一来做这些研究。一些非常有钱又聪明的人出钱成立了这个实验室。其中一个是埃隆·马斯克，但他在2018年离开了。还有一个很大的公司微软，也给了他们很多钱。
除了角色设定，你还可以让 AI 模拟某个具体人物，比如让它用著名作家大卫·福斯特·华莱士的风格改写相同的句子：
Imagine you are the famous writer David Foster Wallace, please rewrite this sentences.
假设你是著名作家大卫·福斯特·华莱士，请改写以下句子：
这样输出会带有该作家的写作风格，内容更具文学色彩：
As David Foster Wallace, I might rewrite these sentences to sound more like this:
OpenAI is a lab that studies something called artificial intelligence, which is like when computers can do things that normally only humans can do. They have a big computer that's one of the most powerful in the world, and they're trying to make sure the AI they create is friendly and helpful. The lab was started in 2015 in a city called San Francisco, and a bunch of important people gave them a lot of money to do their research. One of those people was Elon Musk, who stopped working there but still gives them money, and Microsoft also gave them a lot of money recently.
作为大卫·福斯特·华莱士，我可能会这样改写这些句子：
OpenAI 是一个研究“人工智能”的实验室，人工智能指的是让电脑能够做通常只有人类才能完成的事情。他们拥有一台世界上最强大的超级计算机之一，致力于确保他们创造的人工智能既友好又有用。这个实验室成立于2015年，位于旧金山，一群重要的人士为他们的研究投入了大量资金。其中一位是埃隆·马斯克，他后来离开了实验室，但仍然在资助他们，微软最近也给了他们不少资金。
关于如何运用这个技巧，以及利用 AI 提升写作水平，可以参考 Nat Eliason 的文章《Using ChatGPT as a Writing Coach》，他在写作过程中就大量使用了类似的方法。
