Claude Code × SyncPen: Give Your AI a Place to Write
Claude Code is good at producing text — summaries, drafts, documentation, research notes. The catch is that the text lives in your terminal and tends to disappear when the session ends. SyncPen gives it somewhere to stay: a markdown workspace you can read from, write to, and come back to later. Connecting the two takes a few minutes. Here is how, and why it is worth doing.
Why I built SyncPen
SyncPen grew out of frustration. I am a writer and an engineer, and I wanted one place to write that was calm and minimal, worked with the people I write with, and kept up with the tools I actually use every day. I could not find it, so I built it.
Connect Claude Cowork to Syncpen: a shared brain for you and your AI
Claude Cowork is good at getting things done — researching a topic, drafting a plan, working through a multi-step task. The catch is the same one every agent has: what it produces lives inside one Cowork session, for one person, and it tends to fade when the session ends. Syncpen gives it somewhere to stay — a markdown workspace your AI can read from and write to, and that you (and the people you work with) can open, edit, and build on later.
Publish Straight to Sanity from SyncPen (No Copy-Paste, No CMS Wrestling)
Write it once, in the calm of your editor. Click once. It's live in Sanity — drafts, slugs, images, code blocks and all. No copy-paste, no format-mangling, no second guessing.
Using SyncPen as Your Knowledge Base
Most knowledge bases fail the same way. Notes go in, and nothing comes out — because finding the right paragraph six months later is harder than writing it again. A knowledge base is only worth keeping if you can get back what you put in. And, increasingly, if your AI can get to it too.
