Perplexity
Japanese Perplexity（パープレキシティ）
An AI search service that looks things up on the web, writes the answer in plain sentences, and lists the source pages as numbered citations. Because answers and sources sit side by side, you can open the originals and check.
Perplexity is an AI search service made by a company called Perplexity AI. You ask a question in everyday words, and it searches the web, reads pages, and writes the answer as sentences. Small numbers in the answer link to the pages it relied on. Think of a librarian who finds material, summarizes it, and hands it to you with footnotes. According to its app listing, it runs on AI models from several companies, including OpenAI and Anthropic.
Watch out A numbered citation does not guarantee the page was summarized correctly. Before putting numbers or dates on your website or in a notice, open the source page and check them yourself, and rewrite the answer in your own words instead of pasting it. Before typing internal company material into a question, read the terms of use and privacy settings first.
