Abstract

Social media marketing requires timely, consistent content that is aware of the platform and this is labour intensive and hard to automate without sacrificing authenticity. In this paper we present an agentic web service that automates the end-to-end pipeline of social media content generation, analytics and insight reporting for small and medium enterprises, startups, creators and agencies. The system is a LangGraph state-machine orchestrator written in TypeScript, with supporting Express REST API and React dashboard. All content generation is powered by Qwen3-4B, a large language model with open weights, which runs locally on an OpenAI-compatible llamafile endpoint (i.e., no cloud inference). For LinkedIn, Twitter, Instagram and Facebook we distilll different tone, length, structure, hashtag, call-to-action and audience constraints into a platform-strategy service and gather them in system prompts. Supervised curation graph process, validates and clusters content from Twitter, Reddit, GitHub and general sources. Analytics are computed from CSV datasets normalized into a SQLite schema and provide reach, engagement and sentiment metrics through REST endpoints and visual dashboards. A local Qwen instance is fed a structured summary of computed metrics and outputs findings, issues, and recommendations. It supports two modes of authentication to automate posting to Twitter and LinkedIn.

Full Article/Conclusion

In this project we designed and implemented a local-first, agentic social media content generation and analytics system. The platform includes a LangGraph orchestration layer, a locally hosted Qwen large language model, per-platform and per-business content strategies, a supervised multi-source curation graph, SQLite-based analytics computation, an Express REST API and a React dashboard, as well as authenticated posting to Twitter and LinkedIn. The system successfully demonstrates the feasibility of an end-to-end marketing workflow driven by open-weights inference, from ingesting raw datasets to data-grounded, model-generated insights. Future work includes completing the post-generation graph and its prompt engineering, expanding automated unit coverage to all graph nodes, collecting quantitative generation and insight-quality benchmarks, containerizing the deployment, fixing version-manager inconsistencies in the repo, and hardening the platform clients and authentication flows for production use.
