Get space from your texts.

Decaf is a Mac app that relays important iMessages to you, and organizes the rest.

Decaf is a Mac app that helps you unplug from the compulsive stream of checking and replying to iMessages all day.

Designed for artists, writers and anyone who wants the headspace and clarity of a flip phone lifestyle — without disconnecting from the modern world.

Stay in your group chats and never miss an important iMessagedjulesnowcan you meet at 4:30 instead? or 2FA.

Two paths to regain headspace.

Simple Setup: Decaf Desktop

A calm, monochrome minimalist iMessage app that organizes your texts by importance, and gives you a push notification when something time-sensitive comes through.

  • no unread counts
  • no message previews

  1. Run Decaf on your laptop/desktop.

  2. Decaf intelligently organizes your messages by judged urgency, and groups you create.

  3. Use it to reply to iMessages intentionally, at the cadence of email, when you have the space.

  4. Decaf is intentionally stripped of all addictive UX/UI — so you can simply focus on replying to each message.

Full Setup: Decaf Desktop + Light Phone

A system that allows you to switch to a minimalist phone, and still stay connected for logistics, work, and loved ones — on your terms.

  1. Keep your current iPhone docked at home.

  2. Get a second line (Light/minimalist phone or iPhone) with only the apps you need.

  3. Decaf relays important texts to your second line in real-time, ensuring you're always in the loop on time-sensitive texts. Reply to these messages by texting Decaf directly.

This is the first approach we've found that makes having a minimalist phone realistic.

Why we built it

Why we built it

The sea at dusk, one swimmer far out

  1. Compulsive phone checking is partly caused by the fear of missing an important message.

  2. Checking for something important becomes a neurochemical slot machine — ninety-six checks a day, each one a bet that something important came through.

  3. Each check lowers your baseline dopamine and derails your attention for twenty-three minutes¹ — diminishing clarity of thought, presence, and creative momentum.

  4. Decaf calms this fear by notifying you only if something time-sensitive or important arises to reply to.

  5. Peace of mind means less phone checking. And subsequently, less interruptions from creativity, presence, and focus throughout the day.

Plugged in, on Wi‑Fi: your laptop relays while it's awake. Always on: run Decaf on an old laptop or Mac Mini (~$300) for always-on text-relaying when your laptop is offline.

The model

The model

Run Decaf on a free local source model, or have it utilize Claude for better functionality (recommended).

The model

A small open-source model, running on your Mac. It can sort texts and relay time-sensitive messages, and understand specific commands. More mechanical than natural at understanding context.

What leaves your Mac

Nothing.

Cost

Included.

The model

Claude API judges and sorts texts. Better judgment and understanding of context.

What leaves your Mac

A redacted copy of each message goes to the cloud, and is deleted in 30 days. If you ask Claude to pull up a thread from your light phone, that thread temporarily goes to the cloud as a raw stream of text — no names or where the messages came from.

FAQ

Questions.

What's the smallest way to try it?

The desktop app alone. Run Decaf on your Mac, turn on notifications, and keep your iPhone exactly as it is. Nothing moves, and you can stop any time.

What if the group chat is planning something tonight?

Decaf relays time-sensitive group chat logistics, like when your name comes up or plans are being made, so you're never out of the loop.

What about 2FA codes?

Codes texted to your number land in Decaf's codes group and relay to your second line, so banking, work, and tickets keep working.

Does it work with a flip phone?

Yes. From a Light Phone or flip phone, replies and commands work over SMS, and Decaf asks before anything sends as you. With Claude turned on, you can text it in natural language.

Do I need to be technical?

No. You download the Mac app and follow the setup. If you want the always-on option, an old laptop or Mac Mini does the job.

What leaves my Mac?

With Decaf Local, nothing. With Claude, a redacted copy of each message for sorting, and the full thread only when you ask Claude something from your phone. Never used to train.
