| Description | Pi (short for 'personal intelligence') is a conversational AI companion from Inflection AI designed for empathetic, natural back-and-forth rather than productivity or search. It's aimed at everyday individuals who want a kind, supportive presence to talk through decisions, vent, learn topics, or practice conversation, and it differentiates itself with human-sounding voice options and a distinctly warm, non-transactional tone. It runs free across web, iOS, Android, and messaging apps. | Perplexity AI is a conversational answer engine that searches the web in real-time and provides cited, accurate answers. Used by 10+ million users who need research-grade answers without the noise of a traditional search engine. |
