Daily manual effort to source images, write captions, stay on top of trending topics, and coordinate social media approvals — pulling the team away from core work.

Result

Zero manual effort.
Daily fresh content.

The 24-Hour Automation Cycle

Six coordinated n8n workflows handle every stage — from AI content creation and real-time event detection through Telegram approval to auto-publishing and overnight cleanup.

AI Social Media Content Engine — 24-Hour Automation Cycle

What Makes It Different

Generic scheduling tools post content — they don't create it, react to real-world events, sync your product catalogue, or intelligently expire stale approvals. This system does all of that, autonomously, every single day.

AI-Generated Content

GPT-4o writes on-brand captions using rotating themes while Flux 2 Pro renders matching HD imagery — no designers, no copywriters, no briefs required.

Real-Time Event Intelligence

Monitors external APIs for relevant events and automatically triggers contextual bonus posts — keeping your feed timely and reactive without lifting a finger.

Telegram Approval Loop

Brand owners receive a Telegram preview and a link to the approval dashboard — approve or reject in seconds from any device, without logging into any platform.

Smart Cleanup & Sync

Unapproved posts auto-expire before the next cycle. Product catalogues and hashtag sets refresh on a schedule to stay commercially relevant and algorithmically current.

System Architecture

Six n8n workflows, each handling a distinct concern, composing into one cohesive daily pipeline.

1. Daily Content Generation

GPT-4o selects a rotating theme and drafts a caption. Flux 2 Pro renders a matching HD image. Both are staged in PostgreSQL and a Telegram preview is dispatched for approval.

2. Real-Time Event Detection

A parallel workflow monitors relevant external APIs for upcoming events. When detected, a contextual bonus post is automatically generated and queued alongside the standard daily content.

3. Human Approval via Dashboard

A Next.js dashboard shows the generated image and caption side-by-side. Approve or reject in one click — the system handles publishing or discarding automatically.

4. Auto-Expiry & Cleanup

Before each new cycle, any pending unapproved posts are automatically removed from the queue — keeping the dashboard clean and preventing outdated content from ever going live.

5. Weekly Product & Hashtag Refresh

A weekly workflow syncs the latest product catalogue from your e-commerce platform and rotates active hashtag sets — ensuring every post stays commercially relevant and discoverable.
