Post to 6 social platforms in one click — fully automated, AI-generated content, live run included.
In this video I walk through and run the w57th Social Posting Engine: an n8n workflow that takes a topic brief (via Web Form or WhatsApp) and automatically researches, writes, images, videos, and posts to Instagram, Facebook, LinkedIn, YouTube, TikTok, and X — all for under a cent per run (plus ~$0.26 if you want the AI video, $0.13 for 540p). WHAT’S COVERED━▸ Dual triggers — WhatsApp intake agent + Web Form▸ Content Factory — Grok 4 Fast researches topic via Serper, outputs platform-native copy for all 6 socials as structured JSON
▸ fal.ai FLUX image generation + Kling i2v 6s vertical video (optional)▸ Native n8n nodes for Instagram, Facebook, LinkedIn, YouTube▸ TikTok via Playwright browser automation (API headaches— this is the workaround)
▸ X / Twitter via GetXapi (low rate limit — explained) ▸ Cost breakdown: ~$0.006 per run without video / ~$0.21 with.
