Ask it anything

Subtext knows the whole story.

Should I double text my first date from tonight?
How do I tell my boss I need Friday off?
What's unresolved between me and my sister?
Am I the dry texter? Be honest.
Draft a no that doesn't sound cold.
Who am I neglecting lately?

Tap-to-send drafts, written in your voice.

What it learns

Your texting, decoded.

Every relationship, measured

Reply speed, yours and theirs. Who texts first, who double-texts, who's up at 2am.

One person, read closely

Deep Dive is an honest read of one relationship: the dynamic, the conflict, where it's heading.

Made to be shared

Your archetype, the laugh audit, the clingy award. Cards you send to the person they're about.

Zero stored. All local.

Runs on your Mac

Subtext reads your Messages locally and computes everything on your laptop. Nothing is uploaded, synced, or copied. There is nothing to breach.

The only exception

Ask the coach about someone and that one conversation goes to Anthropic's Claude, the only AI we use. Only after you approve. We never store or log a word of it, and it's never used to train models.

You're in control

Every AI call is opt-in, with the exact scope shown first. Stats and cards never leave the device. Delete the app and nothing remains.

Your move.
