Daily AI Tech News Video Topics: GPT-5-mini + Feishu Bitable

Daily AI Tech News Video Topics: GPT-5-mini + Feishu Bitable — your morning AI shortlist in minutes

This n8n workflow runs every day at 8:00 and automatically pulls fresh AI/tech news, selects the best story for a short Chinese “video script,” and records everything in Feishu Bitable—then sends the final “today’s topic” to a specific Feishu user.

What this workflow does

• Schedules daily execution via an n8n Schedule Trigger set to run at 8:00.
• Finds fresh AI/tech news topics using OpenAI with web search (GPT-5-mini): generates three structured, short-video-ready candidates including title, summary, source, URL, and a recommendation reason.
• Authenticates to Feishu by requesting a tenant_access_token through the Feishu auth API.
• Batch-creates three records in a Feishu Bitable table, writing topic fields plus topic date.
• Chooses the single best topic using OpenAI again, then generates a 120–150 character Chinese news-style script (with a brief selection reason).
• Sends the “today’s topic” message to Feishu by calling a separate n8n sub-workflow that targets the specified open_id. If planning, table writing, or script generation fails, it also sends Feishu alerts via the same sub-workflow.

Use cases

• Daily content ops for an AI/tech short-video channel: auto-pick topics, draft concise scripts, and notify the editor in Feishu.
• SaaS operators tracking AI news: maintain a structured Bitable topic library with links and reasoning.
• Automation engineers: a practical reference workflow combining OpenAI web search + Feishu Bitable + sub-workflow messaging.

Technical details

• n8n nodes / components: Schedule Trigger, Sticky Note, HTTP Request, OpenAI chat (gpt-5-mini with web search tool), Execute Workflow, and a LangChain agent node (n8nn8n-nodes-langchainagent / n8nn8n-nodes-langchainlm chat open ai).
