Perplexity AI

Perplexity is Google for the AI era, dressed in researcher-black. Founded in 2022 by Aravind Srinivas and a team of ex-Google and ex-Meta AI researchers in San Francisco, the product pairs a deep blue-black interface with a single electric teal accent, monospace citation markers, and the information density of an academic paper.

The result is a "library at midnight" aesthetic — serious, citation-rich, and deliberately anti-playful. Where traditional search engines scatter color across ads and widgets, Perplexity strips everything back to dark surfaces, off-white text, and teal hyperlinks that say "this fact has a source." It is how serious people search now.

Perplexity 是 AI 时代的 Google，身披研究者的黑色外衣。2022 年由 Aravind Srinivas 和一群前 Google、Meta AI 研究员在旧金山创立，产品以深蓝黑界面搭配唯一的电光青绿色点缀、等宽字体的引用标记，以及学术论文般的信息密度著称。

最终呈现出一种"午夜图书馆"的美学——严肃、引用丰富、刻意反对活泼风格。传统搜索引擎将色彩散落在广告和组件中，Perplexity 则将一切剥离至深色表面、米白文字和青绿色超链接——它在说"这条事实有出处"。这是认真的人现在搜索的方式。
