Good morning, Zak.
One thread runs through your week.
On your mind
Past the pace you set
You've gone quiet with Sarah.
Down from most days to about once a fortnight since May — past the every-two-weeks you set for her.
Fairly sure
What this is based on 1,204 WhatsApp messages with Sarah and the cadence you set on her file — every two weeks. The gap is now six. Worked out on your phone.

Finding is free. Asking needs a mind.
This finds the words. Asking a question about your life — "how have I been with my sister?" — means reasoning across everything at once, and that runs in the cloud.

This searches what's on your phone and nothing else — nothing you type here leaves it, and nothing is stored.

None is a quiz, and none produces a type — they're the instruments researchers use, in the public domain, scored on your phone.

IPIP-NEO-300
The Big Five, placed against a comparison group.
These are bands, not verdicts. Each shows where you sit next to UK adults aged 30 and over — an open research sample, not a census. A high band isn't better, just further from the middle.
The five domains
OpennessHigh
Fairly consistent across its facets.
ConscientiousnessHigh
Orderly and dutiful — self-discipline is the standout.
ExtraversionAverage
The facets underneath disagree — warm one-to-one, quiet in a crowd.
AgreeablenessAverage
Fairly consistent across its facets.
NeuroticismLow
Steady under pressure, on the whole.
You're the authority on you. Traits move slowly, so I won't rewrite this after a hard week — and anything here is yours to correct.
Your people
Relationships are kept by tending, not by feeling. This is where I hold what you know about them.

🔒Kept private — remembered so you can search it, but never read by the model.
Today
Rough one today. I snapped at James in standup and felt off about it for hours after.
That sounds like it's still sitting with you. Was it the moment itself, or what it might mean about how work's been feeling lately?
Honestly the second one. Everything's felt like too much this month.

Your pull, overall
You 56%Everyone else 44%
You carry your conversations a little more than the people in them. Across 34 chats. It's here so you can notice the rhythm, not keep count.
The pull, chat by chat
Arcane reads your messages once to work out who carries each conversation. In a browser, a copy is kept on our servers and we can read it — on iPhone they stay on the device.
You & Sarah
Who's carrying the conversation.
The pull
You 62%Sarah 38%
Lately, you're carrying this one. You start most threads and reply quicker.
What makes it up
MessagesYou 58% · Sarah 42%
You send more of the messages.
Who texts firstYou 63% · Sarah 37%
You restart most conversations after a quiet spell.
Who has the last wordYou 55% · Sarah 45%
You're usually the one to sign off.
Reply speedYou ~40m · Sarah ~2h
You usually reply sooner than Sarah does.
None of this is a scorecard. Balance shifts with life — a busy month, a hard week. It's here so you can notice the rhythm, not keep count.
Fairly sure
How this is worked out From 214 messages, Jan 2024 – Aug 2025 — 118 from you, 96 from Sarah. "Texts first" counts a message after a 6h+ quiet gap; "last word" the final one before the next gap; reply speed compares typical waits. The overall pull weights message share most, then who texts first, the last word, and reply speed.

Skipped — no readable date3
Three lines had no date Arcane could read, so they aren't stored: something has to sit at a point in time to be reasoned about, and a guessed time would move every gap either side of it.
Which one is you?
The export names who sent what, but never says which of them is you.
Nothing about who carries a conversation can be worked out until this is answered, so it's asked once and remembered. Change it later and every chat is re-read.

Keep a file on Sam?
One chat is a snapshot. A file is the thing that keeps being useful.
Dates that matterTheir birthday, their kids', the anniversary of something hard. Arcane reminds you before, never on a lock screen with their name on it.
A pace you chooseSay how often you'd like to be in touch. Drift is measured against your own wish, never against Arcane's opinion.
This chat, folded inThe messages, the pull line and when you last spoke all attach to the file. Nothing is typed twice.
Arcane never files someone on its own — you decide who gets a file, and you can unlink a chat or delete a file whenever you like. What you write about other people never leaves your device, on any client.
Want a fuller picture?
You've seen how you show up in one relationship. There's more, when you want it — and none of it is required.
Offered once, and it stays where you can find it. Arcane doesn't chase you — no streaks, no badges, no reminder emails.
The app after sign-in, mirrored screen for screen. Home leads with one on-device observation, Coming up, and your life by domain.
