  2. 2.Process requests via AI agent that queries Postgres database
  3. 3.Execute complex operations using specialized tools and conditional routing
  4. 4.Parse and structure outputs into organized formats
  5. 5.Store context and conversation memory in database for continuity
  6. 6.Publish results to Twitter/X or return to user

Use cases

  • Build an intelligent assistant that answers questions based on your company's database
  • Automate data collection from Twitter/X with classification and Supabase storage
  • Create an investigative agent that learns from past queries and improves responses

Requirements

  • OpenAI API key (GPT-3.5 or newer)
