🎬 Generate AI avatar videos with GPT-5 & publish to social media platforms

⚡ 3,571 views · 🎬 Content Creation & Video

💡 Pro Tip — Since TikTok doesn’t have a public API, getting data usually means fragile HTTP scraping. ScraperNode is a community node that gives you clean JSON for TikTok profiles, videos, and comments — drop it into your workflow and skip the parsing.

Description

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.
