AI never gets tired. You do.

Mindful Agent is for people who run AI all day. It waits for the pause between runs and offers one short reset.

noun

AI brain fry

The foggy, wired feeling after hours of prompting, checking, reviewing, and starting one more run. The work is still moving, but your attention is no longer getting better.

The stopping point disappeared.

Claude or Codex finishes, so you inspect the result and start another run. While it works, you open the browser, answer something, or queue the next task. There is always a useful reason to stay.

A few hours later, the tools may still be improving the work. You may not be. Mindful Agent is built for that exact loop—not for every minute you spend on a screen.

What it does

  1. 1

    It notices how long the loop has been going.

    With your permission, it can see run starts and finishes, time at the computer, browser rhythm, calendar gaps, and movement.

  2. 2

    It finds a seam, not a timer.

    It does not interrupt because sixty minutes passed. It waits until the work pauses or an agent can continue without you.

  3. 3

    It offers one small way back.

    Take the break, dismiss it, or turn the stone off. It does not follow up, reward you, or keep score.

Codex has finished. You have been here for two hours and have not moved since lunch. Go outside for five minutes.
The kind of thing it might say.

You choose what it can notice

The stone can stay simple or understand more of your day. Each source is added separately and can be removed later.

Claude Code and Codex
How long sessions run, when they repeat, and when an agent can carry on alone.
Browser
Active time and tab changes. It does not need to read page titles or contents.
Calendar
How full the day is and where there is a useful gap.
Location and weather
Whether stepping outside makes sense where you are.
Apple Health and Watch
Movement, standing, sleep, and workouts through a planned iPhone and Watch companion.

Claude, Codex, browser rhythm, calendar, and rough location are in the current Mac work. Apple Health requires the companion app and is not available yet.

It should be easy to trust

Mindful Agent starts with the shape of your day rather than the contents of your work. If you choose to give it more context, it should tell you what that access changes and show what it recently noticed.

Your choices outrank the stone. You can make it quieter, remove a source, erase what it remembers, or turn it off.

The terminal stone works in Claude Code now. The Mac app is out and keeps itself current.

It reads the timestamps of your own prompts, never the words. Nothing leaves your machine. Silence it any time: npx @rewyld/stone off

a note

I am one of you. I run a software company that helps people slow down, and yes, I use AI agents to build the thing that tells you to step away from AI agents. I see the irony.

I left big tech to become a guide, but I didn’t leave this struggle behind. Five minutes of mindfulness still helps me come back to myself. I built this to put those five minutes inside the loop.

Johan, founder of Rewyld

Four families. Many individuals.

No two stones are quite the same.

Each seed changes the body, lean, size, and gaze. The stone does not regenerate when you return. You keep the one you recognised.

pebble

Low, rounded, and softened by time.

Steady. Gentle and plain.

flint

A knapped wedge with broken outward points.

Direct. Says the useful thing plainly.

obsidian

A compact dark shard with a heavier silhouette.

Reserved. Waits longer and speaks sparsely.

quartz

Clouded rose crystals that gather upward.

Observant. Notices small changes early.

Find your stone

See which one notices you.

They are all awake. Choose the one you recognise.
