Plug any data source into Claude — a newsletter, your product's API, a listings feed. SocialBoy turns it into on-brand, on-voice posts with AI visuals across X, LinkedIn, Instagram & Threads. On autopilot.
Built by Shape — makers of ProductAI. Free while in beta.
SocialBoy is an MCP connector. Point it at any source — a newsletter, your API, a listings feed — and get posts across every platform, in your voice.
From newsletter to published — without writing the same idea four different ways.
Four steps. Sixty seconds for the first three. Two clicks for the fourth.
Create your account in a minute — you get your own private workspace. No credit card.
One click installs the MCP connector. No JSON, no terminal. Web, mobile, or desktop.
Point it at your data — a newsletter or your product's API — and OAuth the accounts you post from.
On-brand posts with visuals, in your voice, on schedule. Review in Slack or let them fly.

“Every new castle that hits our site now posts itself — a branded Instagram carousel and an X thread, in our voice, the morning it goes live. We went from no social cadence to daily without hiring anyone.”
“We pointed SocialBoy at our own release feed and it turned launches into posts across every platform — with brand-aware visuals from our own image engine, so they actually look like us.”
Brand-aware visuals, sized per platform — these are actual outputs for Castle Collector and ProductAI, not stock samples.
