Generate & Publish AI News Avatar Videos with HeyGen and Blotato

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).
