Why I made this

Write the day down. Then live it like it's your last.

“If today were the last day of my life, would I want to do what I am about to do today?”
Steve Jobs, Stanford, 2005

That question never left me.

If any day could be the last, I want to know what I did with it. So for years I've written down every day: what I planned, and what I actually did.

A day isn't just work. It's what you eat and how you move. So they all went on the same page.

Now I talk to AI all day. So my agents write the page, and I read it on my phone.

Real progress is slow, and the world rarely notices.

Chasing approval you can't control is a modern sickness.

You can control one thing: being a little better than yesterday.

Games show you every step. Life doesn't. So keep your own score.

No audience. Just you, getting better.

That list became Yoshi. I built it because I live this way. I think it's a good way to live. So I'm sharing it.

My daily ritual, now with AI. Start the day with what you want to do. End it with what you did that never made the list.

Why Yoshi

A place to keep it.
A nice place to look at it.

One memory, every agent.

ChatGPT doesn't know what you told Claude, and your coding agent doesn't know either. Yoshi is one journal they all read and write. Switch assistants whenever you like; your history stays put.

Native, and nice to look at.

Not a chat transcript, not a spreadsheet. A real app on iPhone, Android and Mac, plus today's to-dos in the menu bar. Open it and your week is just there.

Why not just chat

Chat history is where things go to get lost.

You already tell your AI what you ate and how the gym went. It just ends up scattered through months of conversations, next to recipes and code and everything else. Yoshi keeps it in one place you can add up.

In your chats

One meal, somewhere in thousands of chats.

Every day is an entry. You can add it up, and so can your AI.

The idea

Your bathroom scale is off by a kilo. You still use it.

It doesn't matter, because you step on it every morning and the trend is still true. Yoshi works the same way for food, training and work.

1Guess, don't weigh. "A bowl of noodles" is enough. The calories are an estimate you can fix if you care.

2Write it the way you'd text it. "Pull-ups 10 8 6 5" is a full log.

3Watch the line, not the dot. Weeks of rough logs show you what one perfect day can't.

What goes in

Three things. One week on a page.

Each day holds what you got done, how you trained and what you ate. That's it, on purpose. These are the three choices you make every single day, and the three that add up: what you build, the body you build it with, and the fuel for both. Track more than that and you stop tracking.

Work

To-dos under topics, like a Notion outline. An empty day offers to carry over what's left from yesterday.

Eat

One line per meal. Your AI guesses the calories, protein, carbs and fat. Change any number you like.

Lunch: a bowl of beef noodle soup

Train

Sets the way you'd jot them in your phone's notes: reps, weights, how long it took.
