Lives inside Claude
Any source in. On-brand posts out.
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.
Features
Everything you need to ship four posts a week
From newsletter to published — without writing the same idea four different ways.
Plug in any source
A newsletter, your product's API, a listings feed, a CRM. SocialBoy pulls one item at a time and turns it into a post. Your data stays where it lives.
Voice per account
Your brand voice isn't your founder voice. Tune one per account, refine over time, store them once.
Brand-aware AI visuals
Per-post images in your brand colors and logo, sized for each platform — powered by ProductAI's image engine.
Lives inside Claude
One click installs SocialBoy as an MCP connector. Set up sources, voice, and cadence — and publish — without leaving chat.
Set a cadence, walk away
