Your next deal is sitting in a thread. We make sure you don't forget.
MYNC turns your years of iMessage, email, and calendar into a living map of who you owe, who's cooling, and who to call — computed privately on your Mac. It only has to save one relationship to pay for itself for a decade.

Searching your history
Andrei Petrov — investor at Avra. You've spoken 23 times since February, last on Saturday, when he asked about Q3 burn iMSG·14203. Three open threads worth bringing up:
the onboarding budget iMSG·14180, the Marina intro you owe him iMSG·13977, and the NYC dinner he proposed for April 10 iMSG·14102. He mentioned getting a new puppy two weeks ago VOICE·0419.

PNL·02Pipeline / Capture → Organize → AskOnline3 stages
Three stages. Then it disappears into your day.
Every fact MYNC holds cites the message it came from. No hallucinated memories — you can click through to the receipt.
01Capture & CustodyEncrypted
What goes in — and who holds it
MYNC reads a copy of your history — never your live files — and locks it in an encrypted vault on your Mac. The key stays in your Keychain. Nothing leaves unless you say so.
▸ Messages · Voice · Calendar · ContactsHeld by you · encrypted
02OrganizeStructured
A private map of who knows whom
MYNC organizes your history at four levels — your circles, your people, the facts about them, and the messages themselves — so questions route to the right level instead of keyword-matching everything.
Structured▸ Raw
03Ask & WriteCited
Ask anywhere. Answers come with receipts.
Ask from the MYNC app, from Claude, or from your phone. Every claim links back to the message it came from. Tell it to remember something — it will, and you approve what it writes.
▸ AskEvery answer cites its source
PNL·03Posture / Pick One — It Is the PlanSwitchable4 postures = plans
Pick the privacy posture you're comfortable with. That's the plan.
Where your data flows is what you're paying for — posture and price are one choice, not two pages. Move up for power, down for privacy. Switch anytime, for any reason.

Nothing leaves. Everything runs on your Mac with the AI built into the app — and every other plan can always fall back here.
Pick this ifYou want the strongest privacy guarantee, even at some quality cost.
Hard questions get help from AI models we run — we publish who runs them, nothing is used for training, nothing is kept long. We only see the few messages a question needs — never your history.
Pick this ifYou want better answers than your Mac alone can give, from infrastructure we name in public.
Questions go to Claude, the best model available. No training on your data, nothing kept long — and Anthropic only sees the few messages each question needs, never your history.
Pick this ifYou want the best answers and the smoothest experience.
Bring your own AI accounts — Anthropic, OpenAI, Voyage, Cohere — and your Mac talks to them directly. Your keys stay in your Keychain; we never see them.
Pick this ifYou want to pick the models and hold the vendor relationships.
Keeping your data on your Mac doesn't make every question private — and we won't pretend it does. On hosted plans, answering a question means sending the few messages it needs to the AI provider. They can't train on them, they don't keep them long, and they never see the rest of your history. MYNC always shows you exactly where your data is going. Want nothing in the cloud, ever? Strict is a real plan.
Switch anytime, prorated. The free trial runs at Standard limits. Your limits are always visible in the app, and falling back to Local is always free. Prices come at launch — we'd rather show no number than a fake one.
PNL·04Assurance / Enforced, Not Promised6 guaranteesVerifiable
If we can't enforce it, we don't promise it.
Each guarantee maps to a component, not a policy paragraph.
A·01At restEnforced
Encrypted on your Mac.
The key never leaves your Mac's Keychain. We can't read your data — neither can anyone who steals the file.
ADR-002 · Storage
A·02Your memoryEnforced
You control the map.
Forget anyone or anything, permanently. Every AI-proposed edit waits for your approval, and every change keeps its receipt.
ADR-009 · Write tools
A·03TelemetryOff-default
Off. Actually off.
Diagnostics are opt-in and carry counts — never messages, names, or queries. You see the exact payload before you turn it on.
ADR-010 · Telemetry
A·04InjectionEnforced
A text can't talk MYNC into anything.
A malicious instruction arriving in a text is just text. Incoming messages can never trigger changes to your graph.
ADR-009 · ADR-012 · Caller context
A·05VectorsEnforced
Vectors are as sensitive as the text.
Search vectors can be reversed back into text — so they live inside the encrypted vault too, never beside it.

Your history is already written. Make it useful.
Installs in a minute. Loading a large history takes about 10–15 minutes, and the one-time indexing runs in the background while you use your Mac normally.
