In their own words
Nuju
Nuju is an AI journal and mood tracker for quick emotional check-ins, written or spoken journaling, and reflections on patterns over time. Users can log mood and energy, write an entry, or speak when typing feels difficult; an AI reflection responds to what they wrote. Nuju also surfaces repeated moods, habits, and moments, and offers four coach styles: Gentle, Wise, Tough, and Fun. The product is a progressive web app installable on iPhone, Android, or desktop, with iOS listed as a mobile app platform. Nuju says entries are encrypted at rest and separated through end-to-end account isolation. It also says personal journal content is not used to train general-purpose AI models and personal data is not sold. Users can request access, correction, export, or deletion of their data; account deletion removes associated data within 30 days unless law requires longer retention. The Free plan includes one personal reveal, a 10-second mood check-in, and three saved entries. A 7-day trial is listed.
