Loopcast - Sell Project

A social media drafting tool with a human approval step. A LangGraph agent writes posts for Twitter/X and LinkedIn in a chosen brand voice, and nothing is published until you approve it. What’s included: four built-in voice personas plus a custom persona builder, banned-buzzword filtering and voice scoring, tweet thread and LinkedIn carousel generation, an approval queue with a copy-editing drawer (Sharpen Hook, Condense, Add CTA, diff view), a best-time heatmap, an A/B hook simulator, and a scheduler. Built with FastAPI, LangGraph, React 18, TypeScript, Vite and Tailwind. 55 passing automated tests. Please note: The heatmap, hook simulator and copy tools are rule-based estimates, not trained on real engagement data. AI drafting uses OpenAI (gpt-4o-mini by default) and falls back to a built-in mock generator when no key is set. Twitter/X and LinkedIn adapters make real API calls when given valid access tokens, but the in-app “Connect account” flow is simulated: a buyer must add a real OAuth login flow, or supply tokens, to publish live. Status: Not yet launched. It has no users and no revenue, so you’re buying the code and a head start. What you get: full source code, setup documentation, and 2 weeks of handover support.
