Vesta: AI Journal & Diary

Your journal with a full AI companion that runs entirely on your iPhone — reflections, mood insight, and chat. Private by design. No account. No cloud.

Vesta is a journal with a full AI companion — one that runs entirely on your iPhone. It reflects on what you write, helps you notice how you feel, and talks things through with you. Nothing leaves your device.

Most journaling apps send your most private words to the cloud. Vesta doesn't. The intelligence is Apple's on-device AI, so your entries, photos, voice notes and health data are processed and stored on your phone — never uploaded, never trained on, never seen.

WHAT VESTA DOES • On-device analysis — every entry is gently read for emotion, themes and a one-line summary, instantly and privately. • Talk it through — a warm, reflective conversation about any entry, by voice or text, in the style that fits your mood. • Ask your journal — “When have I felt most at peace?” Get grounded answers drawn only from your own words. • Weekly & monthly reflections — Vesta notices your patterns over time and writes you a calm recap. • Mood & emotions — one-tap check-ins and a rich emotion vocabulary, charted into insight you can feel. • Health & weather insight — see how sleep, activity and the weather quietly shape your mood. • Capture anything — photos, video, voice notes and scanned pages, with on-device transcription and text recognition. • Apple Watch — catch a mood or a quick note from your wrist; it syncs straight to your journal. • Ten languages, including the one the AI writes back in.

PRIVATE BY ARCHITECTURE • 100% on-device AI — no cloud, no AI servers. • No account, no login — we don’t know who you are. • Optional iCloud sync, end-to-end encrypted through your own iCloud — neither Vesta nor Apple can read it. • No ads, no trackers, no data brokers.

FREE & PLUS Journaling, on-device analysis, mood check-ins, capture and Apple Watch are free. Vesta Plus unlocks the deeper AI: Talk, Ask, weekly/monthly/yearly reflections, Health and weather insights, and export — as a monthly or yearly subscription, or a one-time lifetime purchase, with a free trial.

Vesta is a calm, private place to think — not a medical service.

Note: the on-device AI features require an Apple Intelligence–capable iPhone (iPhone 15 Pro or newer). Journaling, mood check-ins and capture work on all supported devices.
