LISTED PROFILE
SELF
SELF is a Japanese conversational AI for daily self-care, built around dialogue with a cast of robot companions that become available as a sync level rises. It learns preferences and routines from ongoing conversation, keeps diary entries, and offers everyday reflections alongside weather, schedule, and fortune suggestions. The app is distributed on iPhone in Japanese, with optional subscriptions that extend memory for certain characters.

01 — OUR TAKE
Who and what it suits
SELF sits at the intersection of self-care and companionship, marketed on the App Store as 'AI self-care' built around seven progressively available robot characters. Its main trade-off is a light free tier with a strict memory boundary: per the official listing, humanoid companions forget after about three days unless a subscription is purchased. Some App Store reviews report short conversation windows and dismissive or hurtful outputs, especially from personality and fortune features, so emotional-support copy must stay non-clinical. The privacy policy lists conversation history, location, and calendar data.
Best for
- Japanese-speaking users who want a daily AI conversation companion that remembers preferences and routines
- People who enjoy meeting new robot companions over time through conversation

Not ideal for
- People seeking diagnosis, therapy, emergency help, or clinical mental-health support
- Users who need Android, English, or Spanish product support
- People who want persistent companion memory without paying a character subscription
- Anyone expecting long, uninterrupted conversations rather than brief check-ins
What stands out
- A long-running Japanese conversational product with an active update history
