Private Long-term Memory for Your AI Coach
Your coach remembers your goals, patterns, and growth over weeks and months — not just today's conversation. All stored privately on your device, never in the cloud.
Private · On-Device · Yours Alone
An AI coach that remembers your story and guides your daily reflection — built entirely on your device. No cloud. No tracking. No compromise.

Every journal entry you write online is stored on someone else's server — forever.
AI coaches promise transformation, then harvest your habits, moods, and vulnerabilities.
Productivity apps demand accounts, subscriptions, and constant connectivity just to think clearly.
You shouldn't have to trade privacy for progress.
Sanctum reimagines personal growth as something sacred — private, intentional, and entirely yours. A calm space where AI listens, reflects, and guides without ever sending a byte beyond your device.
A coach that builds long-term memory of your journey, surfaces thoughtful daily reflection prompts, and grows with you — because it only knows what you choose to share, locally, in your own sanctuary.
"The most powerful companion is one that belongs to you alone."
We're shipping the features people want most — starting with a coach that truly remembers you.
Your coach remembers your goals, patterns, and growth over weeks and months — not just today's conversation. All stored privately on your device, never in the cloud.
Thoughtful, personalized prompts every day — drawn from your own journal and journey. No generic templates. Just the right question at the right moment.

Sanctum was built on a single conviction: your inner life is not a product.
Be first in line for long-term AI memory and daily reflection prompts — plus early access to every feature we ship next. Lock in lifetime founder pricing before spots run out.
You're on the list. We'll be in touch soon.
Sanctum runs optimized language models directly on your phone's processor. Your journals and conversations never leave your device — the AI reads and responds locally, with no internet connection required for core features.
No. Sanctum's core experience — journaling, voice capture, habits, and AI coaching — works without any account or email. An account is only needed if you choose optional features like cross-device sync in the future.
We're launching first on iOS, with Android to follow. Founding members will receive early access on their platform of choice.
Founding members pay once for lifetime access to Sanctum — no recurring subscription. This exclusive rate is limited to our first cohort and will never be offered again.
Absolutely. Your data belongs to you. Export your journals and notes at any time in standard formats — because a sanctuary should never feel like a cage.
We're in active development and targeting a founding member release later this year. Waitlist members will be the first to know.
