against the January cohort
Slide 4 still says 2.4×. Use the September sheet.

Slide 4 says 3× now, from the sheet. I looked at the slide and it fits.

The better AI gets, the more you carry.
You ask in a chat, and the answer stays in the chat. Your deck is still in PowerPoint. So you copy, paste, and fix what broke.
The AI got faster. You became the slow part.
“I'm the human clipboard between my AI and my actual work.”
If that's you, this is the fix.
Send the AI to the work. Not the work to the AI.
yarnnn changes the real thing, on your computer. Nothing is pasted or carried back.

It's in your real files now.
So it shows its work.
Three things a chat never had to do.
Every change has a name on it.
You. Your agent, on Claude. ChatGPT, from its own app. Each change says who made it, and when.
Nothing it does is hidden.
It acts as you, where you allowed, sending and posting included, and lists every step in History. It never takes your pointer.
Needs you
Now
Next
Done
When it can't, it tells you.
It stops and says what's in the way. It never hands you something else and calls it done.

I stopped before changing anything. budget.xlsx is open in Excel with work you haven’t saved, and I won’t write over it.

The AI will change. Your record shouldn't.
Every AI company's agent can tell you what its own models did. None can tell you what all of them did.
yarnnn sells no model. Claude today, GPT tomorrow, ChatGPT from its own app. One record, and it's yours to keep.
Every version has an author.
Every change is signed and dated. Hover a line to see who changed what, and when — you, an AI you connected, or your agent.
a single AI company's record can't show this
Not a black box.
We never train on your files, and by default neither do the AI providers we call. What your agent reads goes to the provider doing that work, and we name every one.
Files on your computer stay on your computer. A Word, Excel or PowerPoint file passes through yarnnn only while it's read or changed, and isn't kept.
Stop being the clipboard.
