description: >-
  Chuck Data is Amperity's first-party command-line/TUI tool - an interactive text UI for data
  engineering across Databricks and AWS (Redshift + EMR) with AI assistance, whose identity-resolution
  capability is powered by Amperity Stitch. It authenticates to Amperity with browser-based OAuth.
scope_note: >-
  Chuck is NOT a CLI over the Amperity REST API - it does not wrap the Amperity API, Profile API or
  Streaming API endpoints. It is a separate product surface that reaches Amperity Stitch and the
  customer's own warehouse. Amperity ships no CLI for its published REST APIs.
