Pi

Pi is a personal AI assistant from Inflection AI built around conversation quality rather than task throughput. It is tuned to be patient, curious, and emotionally literate, which makes it a different proposition from productivity chatbots: people use it to think out loud, rehearse difficult conversations, talk through decisions, or simply unwind.

It supports natural voice conversations alongside text, remembers context across sessions, and offers a gentler, more opinionated tone than typical assistants. Pi runs free on the web and on iOS and Android apps. It suits individuals who want a low-pressure sounding board and reflective dialogue; it is explicitly not the tool for spreadsheet work, cited research, or file handling, and users looking for the fastest factual answers are better served by search-grounded engines.
