💥 TikTok Viral Trend Detector → Seedance 2.0 → Auto-Publish with Blotato
💥 TikTok Viral Trend Detector → Seedance 2.0 → Auto-Publish with Blotato 📄 Documentation: Notion Guide Who is this for? This workflow is built for content creators, social media managers, and automation enthusiasts who want to automate the entire TikTok content pipeline — from trend research to video generation to publishing — without filming anything. It's especially powerful for anyone running faceless content channels on TikTok and Instagram, or agencies managing multiple accounts who need to produce trend-driven content at scale with zero manual effort. > ⚠️ Disclaimer: This workflow uses Community Nodes (Blotato). These are only available on self-hosted n8n instances. What problem is this workflow solving? Creating viral TikTok content requires three separate skills: trend research, video production, and publishing strategy. Most creators spend hours doing each manually — scrolling TikTok for inspiration, editing videos in CapCut, then posting with the right hashtags at the right time. This workflow automates the entire pipeline in one shot: It finds what's trending right now on TikTok in your niche Analyzes the viral pattern (hook structure, emotions, visual style) Generates an original concept inspired by that pattern (no copying) Creates a cinematic AI video with Seedance 2.0 Publishes automatically to TikTok and Instagram via Blotato What this workflow does This automation runs in two parts: Part 1 — Claude Cowork (Trend Intelligence) You prompt Claude Cowork with your niche (e.g., "weird productivity hacks"). It uses Apify to scrape the top viral TikTok videos on that topic, then performs a cross-video analysis to extract the viral recipe: Hook pattern (the first 3 seconds) Narrative structure (list format, before/after, tutorial…) Dominant emotion (curiosity, recognition, surprise) Recurring visual elements Claude then generates 3 original video concepts that apply this viral recipe — not copies, but fresh ideas built on proven patterns. The best concept is sent to the n8n webhook as a structured JSON payload. Part 2 — n8n Automation Pipeline Once the webhook receives the payload, n8n takes over: Webhook receives the trend analysis + selected concept from Claude Cowork Normalize Payload handles both Postman (array format) and direct Cowork formats Google Sheets archives the full trend report (analyzed videos, viral pattern, all 3 concepts) Claude (Anthropic node) generates a Seedance-optimized video prompt: one continuous cinematic scene, no human faces, 9:16 vertical, plus a TikTok caption with hashtags AtlasCloud / Seedance 2.0 generates the AI video from the text prompt (720p, native audio) Polling loop checks every 5 seconds until the video is ready Google Sheets logs the production (video URL, prompt, caption, prediction ID) Respond Success immediately confirms to the webhook caller (before publishing, to avoid timeouts) Blotato publishes in parallel to TikTok and Instagram simultaneously Google Sheets updates the row with publication status and post URLs for both platforms Setup Required accounts: A Claude.ai Pro account with Claude Cowork enabled (for Part 1 — trend scraping and analysis) An Apify account to run the TikTok scraper actor (clockworks/tiktok-scraper). Apify handles the TikTok data extraction — without it, the Cowork agent cannot retrieve viral videos. Credentials to configure in n8n: Google Sheets OAuth2 Type: OAuth2 Used for: Saving trend reports and production logs Connect via n8n's built-in Google Sheets credentials Anthropic API Key Type: Anthropic credentials (built-in n8n node) Get it at: console.anthropic.com Used for: Claude node — generating the Seedance video prompt and TikTok caption Atlas Cloud API Key Type: Header Auth (Authorization: Bearer) Get it at: AtlasCloud Used for: Seedance 2.0 text-to-video generation (HTTP Request node) Blotato API Key Type: Blotato credentials (community node) Get it at: Blotato Used for: Publishing to TikTok and Instagram Install the community node: npm install @blotato/n8n-nodes-blotato How to customize this workflow to your needs Change the niche: Edit the Claude Cowork prompt to target a different niche: cooking hacks, finance tips, fitness routines, language learning — any niche with active TikTok communities works. Change the video model: The workflow uses bytedance/seedance-2.0/text-to-video via AtlasCloud. You can swap it for seedance-2.0-fast (cheaper, 4s max) or any other AtlasCloud-supported model by editing the Seedance - Start Generation HTTP Request node body. Add more platforms: Since Blotato supports 9 platforms (YouTube Shorts, LinkedIn, Pinterest, Threads, etc.), duplicate the Create post node and change the platform parameter to publish everywhere at once. Change publishing schedule: Replace the Webhook trigger with a Schedule Trigger to run the full pipeline automatically every day at a set time. Select a different concept: Claude Cowork generates 3 video concepts per run. Change selected_concept_id in the JSON payload (1, 2, or 3) to test different concepts on the same trend data. Adjust video duration: The workflow currently uses duration: -1 (auto) for the Seedance node. Set it to 4 for faster/cheaper generation, or test higher values depending on your AtlasCloud plan limits. 🎥 Full tutorial: Watch on YouTube 👋 Need help or want to customize this? 📩 Contact: LinkedIn 📺 YouTube: @DRFIRASS 🚀 Workshops: n8n courses (in French) Need help customizing?
