Your life,
connected.

LSTN is the local-first relational intelligence layer that reads what you already see — email, iMessage, Calendar, Contacts — and synthesizes the ongoing situations across them into a small, opinionated Brief.

It's not another inbox. It's the layer above the inbox that tells you what's actually happening.

Your inbox is loud.
Your judgment is quiet.

Email gets you the message.
It doesn't get you the meaning.

Watch it work

What lands across your channels
becomes one read.

Three real shapes of cross-channel synthesis. The inbound rows are what your tools show you, one channel at a time. LSTN's read is what you'd have to figure out yourself, in your head, every morning.

LSTN's read

The "small thing" is the thing. The meeting moved up because they want to settle the cap before you do. Don't walk in expecting a confirmation call.

A two-week pattern
"Excited to keep moving this along — talk soon!"

"Will circle back when I have bandwidth."

LSTN's read

The tone has cooled. "Bandwidth" is a soft no, and two reschedules without a new commit means they're not coming back. Decide whether to push or move on — but stop assuming this is alive.

Cross-channel identity

LSTN's read

The follow-up is the same person, twice. Across email and texts. The reason they're texting you about the email is that you've ghosted them for 10 days. Reply now, before this becomes a story they tell.

It listens to all of it

Everything that touches you,
in one place that thinks.

Email
Gmail and Apple Mail. Every account, in one read.
iMessage
Where the real talking happens — and where the real signal hides.
Calendar
Who's on your day. Who keeps moving the meeting. What got rescheduled and why.
Contacts
One person across every handle they own. The identity backbone.

The Brief

It tells you what to think about,
not what landed in your inbox.

Opinionated statements drawn from across every channel and every month. Some mornings, three. Some, twelve. Some, none.

Sign the LOI before today's meeting.

v2 has been sitting since Tuesday; it's being framed as the deadline. The structure is in your range — but the number's still blank. Don't sign around it.

The acquisition forecast changed overnight.

Texted to you this morning, attached. One target is the live one this month; the rest are stretch fits. Worth ten minutes before the call.

cross-channel tone warmed

Address the silence before today's 1:1.

Eight weeks since you replied to the last note. The meeting was self-booked from their end — that's a tell. Walk in with a posture, not a question.

today's meeting

The honest part

Wait — AI is going to read all my texts?
Fair question. Here's exactly what happens.

LSTN is the only AI tool we know of that's been built privacy-first from line one. Your messages live on your Mac. They don't leave it for storage, ever. Here's the four-boundary truth — no marketing, just the architecture.

Stays on your Mac
Your email, iMessage, Calendar, and Contacts.
All of it. AES-GCM encrypted at rest in your local Application Support folder. No cloud upload. No "we'll just store a summary." Your data lives where it's always lived.
Briefly crosses to AI
Excerpts go to Claude when LSTN writes your Brief.
Anthropic holds them 30 days for safety review, then deletes them. They don't train on your data. Same posture every other AI tool runs on. If that's still a no, flip Local-Only Mode in Settings — synthesis falls back to a deterministic version that never leaves your Mac.
What we see
Nothing.
There's no LSTN server reading your data. No analytics dashboard at HQ. No "we noticed you got 47 emails." We literally cannot read your data because we never get it. The architecture makes it impossible, not policy.
What you control
Three switches, always available.
Local-Only Mode blocks every outbound call. Wipe Everything deletes every store, cache, log, and token in one click. "What we sent Claude" is a line-by-line audit log of every byte that's ever crossed the boundary.

Privacy isn't a feature for us. It's the reason this product can exist.

Why we're capped at twenty

We want twenty loyal users.

Not subscribers. Not free trialists. Not "we'll see how it goes." People who'll open LSTN every morning, tell us what's broken, and stay through the rough early versions.

The Brief gets sharper with use. The cross-channel reads get smarter as we watch what you correct. We need users who'll see that arc — not who'll churn after a bad week.

If that's you, $14.99/month covers what we'll spend running yours. There's no margin. We're building this with you, not for you.
