It has 9 nodes, 3 of them AI nodes (AI Agent, OpenAI Chat Model and Window Buffer Memory). The notes inside the workflow say: “This workflow automatically creates a social media post caption in an editorial plan in Airtable.

Welcome to my AI Social Media Caption Creator Workflow!

This workflow automatically creates a social media post caption in an editorial plan in Airtable. It also uses background information on the target group, tonality, etc. stored in Airtable.

This workflow has the following sequence

  1. Airtable trigger (scan for new records every minute)
  2. Wait 1 Minute so the Airtable record creator has time to write the Briefing field
  3. retrieval of Airtable record data
  4. AI Agent to write a caption for a social media post. The agent is instructed to use background information stored in Airtable (such as target group, tonality, etc.) to create the post.
  5. Format the output and assign it to the correct field in Airtable.
  6. Post the caption into Airtable record.

The following accesses are required for the workflow

  • Airtable Database: Documentation
  • AI API access (e.g. via OpenAI, Anthropic, Google or Ollama)

Example of an editorial plan in Airtable

For this workflow you need the Airtable fields "created_at", "Briefing" and "SoMe_Text_AI"
