Is my content private?

Yes — Specter is built local-first, and that shapes everything about how your content is handled. Your posts sync directly between your Mac and your own Ghost blog’s Admin API. There is no Specter server in the middle, no account on our end that your content passes through, and no copy of your blog stored in our cloud. The markdown files live in a folder you pick on your own disk, and the connection runs straight from your machine to your site.

Your Ghost Admin API key is stored locally too, in a config file on your Mac with restrictive permissions, not uploaded anywhere. The only network calls Specter makes for syncing are to your own Ghost blog. (It does check your license with the store when you activate Pro, but that exchange involves your license key, not your posts.)

The practical upshot is that this is the opposite of an AI-writer tool that ingests your content into someone else’s cloud. Specter brings your blog down to files you control so that the tools you choose can work on them. If you want to understand the build-vs-buy reasoning behind that design, see why not just use the Ghost API directly.
