Hey Product Hunt 👋 I'm the dev, and I'll be honest — I built Specter for myself first and only later figured other people probably hit the same wall. I run a Ghost blog, and Ghost is lovely for writing one post and hitting publish. But the moment you want to do anything across the whole blog it falls apart: no find-and-replace, no AI, no editing in your own tools. The thing that actually broke me was SEO — I wanted to mass-update meta descriptions, fix alt text, repair internal links, and refresh a few hundred old posts. In Ghost that's opening every post one at a time. So I started duct-taping scripts against the Admin API. The real unlock was getting my posts out of Ghost and onto disk as plain markdown. Once they're just files, everything works — I write in Obsidian, and for the big jobs I point Claude at the folder and let it work the whole archive at once, then it syncs back to Ghost. Specter is that two-way sync, cleaned up into a little Mac menu-bar app. The piece I lean on most is the dry-run: it shows you exactly what's about to change before it touches anything, which is the only reason I trust letting AI loose on my entire blog. What surprised me is how much else opens up once your blog is markdown on disk: version history + undo (drop the folder in git — Ghost has neither), real backups you actually own, and translation. That last one's where I'm headed next — I'm using Specter right now to build a full multilingual version of my blog. One thing I'm upfront about: Ghost stores posts as Lexical, so card-heavy posts (callouts, buttons, etc.) don't always survive an HTML round-trip perfectly. Plain prose is rock solid, and the dry-run catches surprises before they ship. It's a one-time purchase (no subscription) with a free tier, so you can pull your whole blog down and poke at it before paying anything. I'll be around all day — would genuinely love feedback, and especially curious how the rest of you are managing Ghost at scale today.
