Why Syntrofos

Built to be the AI you actually want to talk to.

Long-term memory, smart reminders, personalities you choose — all designed to feel calm and personal.

Long-term memory

Syntrofos automatically remembers the important things you share — preferences, names, context — so every conversation feels more personal.

Smart reminders

Set reminders naturally in conversation, or let Syntrofos pick up important dates on its own — birthdays, meetings, anniversaries.

Choose your personality

Friend, partner, motivator, listener, or something in between. Tune traits, tone and humour so the conversation feels right for you.

Personal AI profile

Give your companion a name, age, education and conversation style. Your AI becomes truly yours — not a one-size-fits-all assistant.

Privacy first

Your conversations and memories stay under your control. No ad tracking, no data resale — built around your data from day one.

Native on iPhone

Built for iOS first, optimised end to end. Pin to Lock Screen, Action Button and home-screen widgets — it's right where you need it.
