Download

Download, drag, done.

blogwriter runs on your own Mac, through the Claude subscription you already have. No account to make here, no terminal, nothing sent to a server.

Download for macOS blogwriter 0.1.0 · 1.3 MB · macOS 11 or later · Apple Silicon and Intel

The first time you open it, macOS will stop you.

Here is exactly what it says and exactly what to press. It happens once.

  1. Open the downloaded file and drag blogwriter onto the Applications folder beside it.
  2. Open your Applications folder and double-click blogwriter.
  3. macOS shows a warning. Press Done — not the blue button. The blue button says Move to Bin and deletes the download. macOS makes it the default, so pressing Return throws the app away. The macOS dialog: blogwriter Not Opened, with Done and a blue Move to Bin button. Nothing was scanned. macOS says this about any app whose maker has not paid Apple’s yearly fee. We have not, yet.
  4. Open System Settings → Privacy & Security and scroll down to Security. Press Open Anyway, then confirm with Touch ID or your password. The Security section of Privacy & Security: blogwriter was blocked to protect your Mac, with an Open Anyway button. Open that settings page — works if you are reading this on the Mac you are installing on.
  5. Double-click blogwriter once more and press Open Anyway.

That is all of it, and never again. From then on blogwriter opens like anything else and starts by itself when you log in.

What happens when it opens

A blogwriter window opens with the writing page in it — no browser, no address bar. First launch takes about a minute while it fetches what it needs, and the window says where it has got to. No admin password, nothing installed system-wide.

It does not sign you in to Claude. You do that yourself, in your browser, through Anthropic’s own program — blogwriter never sees the token. You need a Claude subscription: it does the writing, on your machine, so your drafts never reach a server.

To remove it: in Finder press ⇧⌘G, type ~/.blogwriter, and double-click uninstall.command. It keeps your settings and keys. Opening a newer download is how you update.

I would rather use the command line

Then skip the download and the five steps — a script from a terminal is not quarantined, so macOS does not ask. It installs the same files in the same places, and the two are interchangeable afterwards.

curl -fsSL https://blogwriter.pro/install.sh | bash

To remove it that way: curl -fsSL https://blogwriter.pro/install.sh | bash -s -- --uninstall.

Show me the script before I run it

Fair. Piping a script from the internet into a shell is a matter of trusting whoever serves it, so here it is in full, and it is the same file that line downloads. The blogwriter download it fetches is checked against a hash built into the script; if the bytes do not match, it installs nothing.
