The Claude desktop app is fine for a quick question. The moment you work across many files it slows down, and everything you did is buried in a chat thread. So I run Claude Code inside VS Code, a free editor, even though almost none of my work is coding. Your files sit down the left, Claude works beside them, and you approve every change.
In the desktop app, everything you do lives in one long conversation. You cannot see your files, and last week's work is somewhere up the scroll.
VS Code is a free editor. You open a folder, see every file down the left, and open any one in the middle. Claude Code sits in a panel beside them, reading and editing the files while you watch.
A free editor from Microsoft. Your files line up down the left, and any document opens in the middle, the way notes open in a Notion page. You never have to write code to use it.
The Claude panel sits beside your files. You type in one window while it reads and edits the files in the next, and it shows a before-and-after on every change before it saves. You can even run more than one at a time.
Everything stays as real files in a folder on your computer. Nothing is trapped in a chat thread. Next week you open the same folder and it is all still there, exactly as you left it.
In the app your work lives in a conversation. Here it lives in files you can see, open, and keep.
Anyone who runs real work across a lot of documents, in property or any business. Almost none of what I do in here is coding. If you keep deals, numbers, and reports in scattered files and chats, this pulls them into one place you control.
You do this once. After that, starting work is just opening a folder, and Claude is already sitting beside your files.
code.visualstudio.com. It is built for code, but you never have to write any to use it as a workspace.Ctrl+Shift+X on Windows or Cmd+Shift+X on Mac, search Claude Code, and click Install. You need VS Code version 1.98 or later.Open Folder..md file and press Ctrl+Shift+V, or Cmd+Shift+V on Mac, for a clean side-by-side preview.You need a paid Claude plan, from twenty dollars a month on Pro, but no API key and no coding. Claude shows a before-and-after diff and asks permission before it changes any file, so nothing is edited without your say-so. Menu names shift a little between versions, so if a label does not match exactly, look for the nearest equivalent.
The point of a folder is that your work compounds. You set this up once, and every month after that is two prompts.
You will build three files in one folder and let Claude keep them current: a tracker of what you own, a log of what came in, and a report for your partners.
portfolio.md is your holdings, one row per property. You build it with Prompt 01.
income-log.md is a month-by-month log of rent received and expenses. You build it with Prompt 02.
CLAUDE.md is a short standing note that tells Claude who you are and what to do with new figures. Claude reads it automatically every time you open the folder. It is the plain-file version of the instructions you would set on a Project in the app. One line is enough to start: "I am a property investor. This folder is my portfolio. When I paste bank figures, update income-log.md and flag any rent that did not land."
No portfolio details ready? Download these sample files, drop them into your folder, and edit the rows. They are filled with obvious placeholder data, so you can run the whole workflow today and swap in your real numbers later. The update file shows what Prompt 03 gives you back.

I am setting up a folder to track my property portfolio. Create a file called portfolio.md with a clean table, one row per property. Columns: property name, price paid, current value, mortgage outstanding, monthly rent, lease end date. Here are my properties, one per line: [property name, price paid, current value, mortgage, monthly rent, lease end] [add one line per property] Show me the file before you save it.
Update my income log for [month]. Here is what came in and went out: - rent received: [paste each property and the amount] - expenses: [paste each item and the amount] Add this to income-log.md as a new [month] section. Then compare the rent received against the monthly rent in portfolio.md, and tell me which properties are short or missing, and by how much.
Using portfolio.md and income-log.md, draft a one-page update for my partners for [month]. Save it as [month]-update.md. Cover: - rent collected versus expected, with the shortfall - anyone in arrears - the total cash position for the month - one line on anything worth flagging Keep it factual and short. Pull every number from the two files, and note anything you had to assume.
Save the folder and you are done. Next month you only run Prompt 02 and Prompt 03. Because CLAUDE.md sits in the folder, Claude already knows this is your portfolio and what to do with new figures. Every edit shows as a diff you approve first, so you stay in control of every file.
Message me directly if you get stuck installing the extension, or you want a second pair of eyes on your first workflow. If property is part of your plan, I can also walk you through the opportunities I am tracking right now.
Message me on WhatsAppOne folder holds your tracker, your logs, and your reports. You open it and everything is there, current and in order, instead of scattered across chats and spreadsheets.
It is faster than the app, it breaks less often, and nothing you do is trapped in a conversation. Run more than one at a time, so one file updates while another is being written.
