DAGL

DAGL and AI functions in spreadsheets: when to use each

An AI function answers one question in one cell, inside the spreadsheet you already use. That is the fastest way to try AI on a short list. DAGL runs the same check on every record, tests it against your expert's answers, shows the cost before the run and keeps every version.

Use an AI function when
  • You have a short list and one question.
  • One person checks the answers by eye.
  • The answers do not need to hold up later.
Use DAGL when
  • The same check runs on hundreds or thousands of records.
  • Your expert must agree with the answers before you rely on them.
  • Someone will ask how an answer was made.

Where AI functions win

  • Nothing new to learn. The function sits in the spreadsheet your team already has open.
  • Fast to try. One formula gives an answer in seconds.
  • Already paid for. It often comes with a licence you hold.

Where DAGL differs

  • Checked against your expert. Agreement is counted on real cases before you run everything.
  • Cost first. Each run shows its rows and its cost before anything is sent.
  • Every version kept. Compare two versions on the same cases, and go back.
