Platformized Purpose Nudging

AI social apps that ingest calendars, photos and messages to auto‑generate 'life purposes' and then nudge users toward intentions create a new category of platform: an ambient moral coach. These services turn existential guidance into product flows (prompts, reminders, peer encouragement) and thus centralize authority over what counts as a 'meaningful life' while capturing highly sensitive behavioral data. — If scaled, purpose‑discovery platforms raise major public‑interest issues—privacy, behavioral manipulation, commercialized morality, and who sets normative standards—so regulators, ethicists and mental‑health professionals must confront how to audit provenance, consent, and monetization before such apps become mainstream.
