昨天又熬到凌晨三点，就为了赶一篇公众号推文。脑子里空得像被洗过一样，对着闪烁的光标发呆。最后实在没辙，打开某个据说"免费"的AI写作网站，输 入关键词，生成了一篇。结果呢？文章是出来了，可读着就像隔夜的馒头，又干又硬，还没法直接发bu到后台，得我一个一个平台去粘贴。 关键是，第二天我就发现，另一家同行的号上，出现了几乎一模一样的文案。 就这，还叫"免费"？我花的时间、掉的头发，哪样不是成本？所谓的免费，很多时候给你的是最基础、最同质化的东西，把你框在一个小格子里。真正的免 费，应该让你摆脱重复劳动，把时间用在更有价值的地方，对吧？ AI写作工具真的完全免费吗 市面上很多工具确实挂着"免费"的牌子。比如一些轻量级的，帮你润色几个句子，或者给点写作灵感。还有些大厂的入门API，每月送你一定额度。但当你 真想靠它吃饭，给网站、给一堆自媒体账号持续供血的时候，瓶颈马上就来了。 要么是生成次数用完了，要么是功能被阉割得只剩基础款。你想批量处理？想自动发bu？想确保内容不重复？对不起，请升级高级会员。这感觉就像给你一 辆自行车，却让你去跑货运。 所以你看，单纯比较"要不要钱"挺没劲的。得看它到底替你省下了什么，又创造了什 ...

Core Viewpoint - The article discusses the rapid advancement of AI-generated content across various forms such as text, images, and videos, emphasizing the need for individuals to develop skills to discern between human-created and AI-generated content [5][24]. Group 1: Identifying AI-Generated Text - AI-generated text often exhibits a distinct "flavor," characterized by overly precise language and emotional dilution, making it easier to identify [8][10]. - Common traits of AI writing include excessive use of complex vocabulary, a barrage of examples and metaphors, and a lack of personal experience or unique insights [9][10]. - AI text tends to be overly polished and consistent, lacking the natural rhythm and emotional fluctuations typical of human writing [9][10]. Group 2: Identifying AI-Generated Images - AI-generated images can be scrutinized for key details such as hands, teeth, and eyes, which are common areas where AI makes mistakes [12][13]. - Consistency and logic in lighting, shadows, and background elements are crucial for identifying AI images; discrepancies can indicate AI generation [15][17]. - Observing texture and symmetry can also reveal AI-generated images, as they may appear unnaturally smooth or overly perfect [17]. Group 3: Identifying AI-Generated Videos - AI-generated videos often struggle with replicating human facial expressions and may exhibit unnatural eye movements or facial symmetry [19][20]. - Illogical actions in videos, such as the absence of typical human habits, can signal AI involvement [20][21]. - Trusting one's intuition about the overall feel of a video can be a valuable tool in identifying AI-generated content [21]. Group 4: Tools for Detection - Various AI detection tools are available to analyze text, images, and videos for signs of AI generation, including Grammarly, ZeroGPT, and deepfakedetector.ai [23][24]. - No single detection tool is 100% accurate; combining multiple methods and tools is recommended for better reliability [24]. - The ongoing evolution of AI technology presents a continuous challenge in distinguishing between human and AI-generated content, necessitating critical thinking and media literacy [24].
