About Blogwriter
blogwriter is a Mac app that reads your site once, learns what you sell, how you sound and what you can't claim, then writes researched, interlinked blog posts from a topic and a target keyword. It runs on your own Claude subscription, so no API key is needed for writing, and drafts never leave your machine.
Each run follows a fixed pipeline: the reader's question, research, draft, AI-tell lint, figure checks, diagrams, interlinking and publish. Only the judgment steps use the model; the rest is plain code. Every figure is traced to a source, and the run stops rather than ship a number it can't trace.
It is built for site owners and content marketers who want a steady blog that stays on-brand. Posts arrive as drafts, previewed on localhost, and publishing is a separate step, including into your own CMS through a simple blog API. Plans start at $19 a month, with five posts free.
What Blogwriter does that nothing else does
It reads your site first to build a brief, holds every post to it, and stops the run rather than ship a number it can't trace. It runs locally on your own Claude subscription.
Who Blogwriter is for
Site owners and content marketers who want researched, on-brand blog posts without writing each one by hand.

How does Blogwriter use my Claude subscription without an API key, and what data is sent during writing?
