How this works
Stay ahead in content creation by automatically generating and sharing engaging AI avatar videos on your social channels whenever trending news breaks. This workflow fetches the latest stories from Hacker News, uses OpenAI to craft a concise script and generate a lifelike avatar narration, then publishes polished videos across Instagram, Facebook, LinkedIn, TikTok, and Pinterest via Blotato. Ideal for news enthusiasts, marketers, or influencers aiming to build a consistent online presence without manual effort, the core step transforms raw headlines into ready-to-post multimedia content.
Use this workflow for daily or hourly automated news updates to boost engagement on visual platforms, especially if you manage multiple social accounts. Avoid it for non-visual content like text-only blogs or when real-time immediacy trumps scheduled posts, as the cron trigger runs on fixed intervals. Common variations include swapping Hacker News for Twitter trends or adding email notifications for video approvals before publishing.
About this workflow
AI Avatar for Trending News. Uses httpRequest, openAi, scheduleTrigger, agent. Scheduled trigger; 29 nodes.
