Private AI therapist & life coach · macOS

A coach that truly knows you — and never leaves your device.

SelfOS is a calm, deeply personal AI companion for reflection and self-coaching. It gets to know you, remembers across time, and keeps everything in encrypted files that live on your computer — powered by your own Claude API key.

No account. No servers. No tracking. Your data never touches us.

Encrypted & private Plain files you own Powered by Claude

Everything in one calm place

Not a chatbot. A companion that grows with you.

Most AI tools forget you the moment you close the tab. SelfOS is built to remember, connect the dots, and gently move you forward — across sessions, dreams, relationships, and time.

Coaching sessions

A streaming, judgment-free AI coach grounded in who you are — to think out loud, untangle a feeling, or work a problem.

Gets to know you

A warm, guided onboarding builds a rich personal portrait — and quietly keeps it up to date as life changes.

Living memory

Confidence-rated insights, organized by life-area, that reconcile themselves over time — and that you can edit, flag, or correct.

Proactive, not passive

It follows up on your goals, spots patterns across sessions and dreams, and nudges next steps — fully tunable, never naggy.

Guided exercises

A library of self-guided exercises informed by CBT, ACT, GROW and more — pick one, or get a smart "suggested for you".

Dreams & AI imagery

Capture dreams in seconds, work through a guided analysis, track recurring patterns — and visualize any dream as AI art.

Built for couples & households

A graph of people and relationships where each person's coaching can draw on shared context — with relationship-scoped privacy.

Questionnaires & compatibility

Send hand-written or AI-drafted questionnaires in-app or via a private link — or run a two-person compatibility check.

Relationship & intimacy tracking

A frictionless intimacy check-in and a partner dashboard — connection, desire, appreciation, conflict — both-consent, never covert.

You hold the keys

Encrypted at rest with a key only your devices hold. Recovery phrase, multi-device join, device revocation and key rotation.

A coach with real memory

It remembers — so you don't have to start over every time.

Every session, dream, and answer becomes a durable insight. SelfOS keeps them organized, rates its own confidence, and reconciles them as it learns more — so the coaching keeps getting sharper.

  • Insights grouped by life-area, with provenance you can trace
  • Tracked goals & commitments it can follow up on
  • Correct it any time — edit, delete, or flag "this isn't right about me"

Dreams, explored

Capture a dream in seconds. Understand it when you're ready.

Brain-dump the dream, then work through a gentle, guided analysis. SelfOS surfaces emotional themes and possible waking-life connections — and can turn the whole thing into a single piece of AI art.

  • Guided analysis: emotions, symbols, and reflective questions
  • Cross-dream patterns & a gentle recurring-nightmare nudge
  • "Visualize this dream" — private AI imagery, stored encrypted

How it works

Set up once. It's yours from there.

1

Choose your vault

Pick a folder for your data — local, or a synced folder like iCloud or Dropbox to use it on more than one device.

2

Add your Claude key

Bring your own Anthropic API key. SelfOS uses it directly — there's no middleman and no subscription to us.

3

Tell it about you

A warm, guided intake builds your portrait, so the very first session already understands your world.

4

Reflect & grow

Talk, journal, dream, set goals. SelfOS remembers, connects the dots, and gently checks back in.

Privacy, by architecture

Your inner life shouldn't live on someone else's server.

SelfOS has no backend and no account. Everything you write stays in encrypted files in a folder you control. The only thing that ever leaves your device is the specific message you send to Claude when you choose to use an AI feature.

Encrypted at rest

Private content is encrypted with a master key only your devices hold — protected by a recovery phrase and an owner PIN.

Plain files you own

No proprietary database. Your data is portable, inspectable, and yours — back it up or move it like any other folder.

Sharing means "informs their AI"

In a household, shared context can help a partner's coach — but it's never shown to them, and you scope it by relationship type.

Good questions

The things people ask first.

Is SelfOS therapy?
No. SelfOS is a wellness and self-help tool — it is not a medical device, not therapy in the clinical sense, and not a substitute for professional care. It draws on therapeutic frameworks to help you reflect, but it doesn't diagnose or treat. If you're in crisis, contact local emergency services or a crisis line.
Is my data really private?
Yes. There's no backend and no account. Your content lives in encrypted files in a folder you choose, on your own machine. The only outbound network calls are the messages you send to the Claude API (with your own key) and a lightweight version check to GitHub — which sends no personal data and can be turned off.
Do I need a Claude API key? What does it cost?
SelfOS itself is free and open. The AI features use your own Anthropic (Claude) API key, billed directly to your Anthropic account — there's no subscription to us. SelfOS includes per-person and household budgets, prompt caching, and a usage view to keep costs visible and in check.
Which platforms are supported?
macOS today (the build is currently unsigned, so first launch needs a one-time Gatekeeper bypass — see the README). An iPhone companion that shares the same vault over iCloud Drive is in the works. Windows and Linux are later phases.
Can my partner or household use it too?
Yes. SelfOS supports multiple people and the relationships between them. Each person gets their own coaching, and you choose exactly what context is shared — scoped by relationship type. "Shared" means it can inform the other person's AI, but is never shown to them directly.
Is it open source?
The source is public on GitHub, built spec-first and slice by slice. You can read every line, build it yourself, and see exactly how your data is handled.
