How it works

Ask once.
The work is done where it lives.

Three places: the conversation where you ask, the run you watch, and the record. The work itself happens on your computer.

  1. 01

    Ask in a conversation

    Say what you need, the way you would to a person. Point at a file, or a page in your browser. Pick the AI behind your agent for each chat: Claude, GPT, Gemini, Grok or DeepSeek.

    Write up this week’s pipeline from the sheet, like last Monday’s note.

    • Read pipeline.xlsx
    • Read last Monday's note
    • Wrote pipeline-note.md

    Done. Three deals moved, and I flagged the one that slipped.

    Do this every Monday at 9.

    It works on your computer's files

    Get the desktop app and switch on This computer. Your agent changes Word, Excel and PowerPoint files where they are, on Mac and Windows. On a Mac it also works in Keynote, Pages, Numbers and your other programs.

    Slide 4 still says 2.4×. Use the September sheet.

    • Read september-numbers.xlsx
    • Changed slide 4 of board-deck.pptx
    • Looked at slide 4

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

    It works on websites, in your browser

    Add yarnnn to Chrome. Your agent works in a tab of its own, with the sign-ins you already have. Close yarnnn and it finishes while Chrome is open.

  4. 04

    You watch, and every step is listed

    Each step is said in plain words as it happens, and listed in History after. It does what you asked, as you. If it can't reach something, it says so.

    Everything is on the record, signed

    Every change says who made it and when. Workspace files keep every version. A file on your computer stays there, and yarnnn keeps the history of who changed it.

    Work that repeats is asked for the same way

    Say when it should happen again. It runs on your schedule, and a run with nothing new to read costs nothing. On a website, it waits for you to start it.

  7. 07

    Reach it from the AI you already use

    Connect ChatGPT, Claude or any AI that speaks MCP. It reads and writes the same workspace under its own name. Export everything as a plain git repo, any time.

Your machine stays yours

It works behind you, as you

It never takes your pointer or keyboard, and every step it takes is listed in History.

Every change signed

A name on every change

Every change carries the name of whoever made it, human or not.
