How it works
Schedule Trigger — runs daily at 10:00 (adjustable).
RSS Feed Read — collects fresh AI/LLM news from multiple feeds.
AI Agent — analyzes news, picks the most viral story, and drafts a 30-second script.
OpenAI nodes — create:
a short, catchy video title
a short caption for social media
a long caption with hashtags
HeyGen API — generates a vertical avatar video (9:16) using your selected avatar_id, voice_id, and optional background video.
Wait node — checks the processing status of the video.
Blotato API — uploads the video and captions for publishing.
Optional publish nodes — preconfigured for TikTok, Instagram, YouTube, Facebook, etc. (disabled by default).
Requirements
n8n v1.105.4+ (cloud or self-hosted)
HeyGen account with API key + avatar_id + voice_id
Blotato account with API key and platform IDs
Setup steps
Import the workflow into n8n.
Create credentials in n8n (⚠ do not hardcode keys):

Customization

Visuals — replace the HeyGen avatar, voice, or background video for a different look.
Publishing — connect only the social platforms you actually use.
