Substack is adding an AI detection feature

AI 中文解读

Substack最近联手AI检测公司Pangram，推出了一项新功能——让读者轻松识别平台上哪些文章是AI写的。核心亮点：以后刷Substack文章，系统会直接告诉你这到底是不是AI生成的，创作者还得老实交代自己用了多少AI。通俗解读就是，Substack给每篇超过100个单词的文章装了个“测谎仪”，读者一点就能看到AI写作成分的评估结果。创作者那边也多了个声明栏，得自己说清楚有没有用AI、怎么用的。这个功能今天开始对网页版和iOS用户开放，安卓版还得等等。不过Substack在公告里嘴挺狠，吐槽了LinkedIn上AI垃圾内容泛滥，还发明了个新词“Claudefishing”，指那些用AI伪装真诚糊弄人的行为。但话说回来，再牛的AI检测工具也做不到百分百准确，连他们合作的Pangram也不例外。Substack自己也承认检测有局限性，强调这些新措施主要是为了给读者一个心理预期，让大家“知道自己读到的是什么”。对普通人来说，以后刷文章能多份参考，至少能判断对方是不是在用AI水内容，省得被“假深情”忽悠了。

News AI Substack is adding an AI detection feature The company has partnered with Pangram for the new tools. By Anna Washenko July 21, 2026 2:54 pm EST Substack Substack has launched a new AI detection tool in partnership with Pangram. This will allow readers to scan Substack content for an assessment of how much of the material was written by AI. The tool can be used on text longer than 100 words that was published beginning today. Substack is also adding a new statement space for creators to explicitly share if and how they used AI for their content. The AI detection capabilities are available starting today on web and iOS, with Android support to come. The blog post announcing the feature is surprisingly spicy. There's a dig at LinkedIn about the presence of AI-generated content on that service and it dubs attempting to create feigned human connection with AI slop "Claudefishing." Throwing shade is a risky maneuver here, because even the best tools for identifying gen-AI can't guarantee a correct assessment. The Atlantic dug deeper into just how accurate AI detection tools, Pangram in particular, can be. Spoiler: they're far from perfect. Substack did acknowledge in the post that there are limits to what Pangram can detect and hinted at some other features it is considering around AI content and preferences. It emphasized that these new measures are aimed at setting expectations for readers, summing up its stance as "people should know what they're getting."
