ARCANE

Understand your life.
Improve your arc.

A private AI brain. It brings together everything already scattered across your apps — your people, your money, your health, your days — and reflects it back so you can live better. Yours alone, never sold.

The problem

Every app knows a slice of you. None of them know you.

Your life is already fully documented — it's just fragmented and dumb. No single app sees the whole picture, so nothing can reason about you as a whole person. Arcane does.

What it does

It connects the dots across your whole life — and reflects them back.

Calm, private, and honest about what it knows. One place that notices what no single app could — and holds every belief about you loosely, for you to correct.

Good morning, Zak.
One thread runs through your week.
On your mind

You and Sarah have drifted a little.

Your chats have thinned since May — and the quiet weeks line up with your busiest ones at work.

What I've noticed

You've gone quiet with Sarah.

Messages have slowed to once a fortnight — down from nearly every day through spring.

The model

Free is a mirror. Paid is a mind.

One app, one subscription switch. The free tier is genuinely useful and fully private — which is what earns the right to offer the paid brain.

Free — the mirror
On-device · £0 · no data ever leaves the phone
  • Import & organise your apps, locally
  • Your data, reorganised by life-domain
  • Statistical teaser insights

Why now: on-device models (Apple's foundation models) make a genuinely private free tier viable for the first time, while frontier models (Claude) make the paid brain possible. The privacy stance isn't a constraint — it's the wedge.
