In plain words

What happened: Calls are over a minute shorter on average.

How to do it yourself
Our suggested steps. The company didn't publish theirs.
- 1
Collect every doc your front-line staff look things up in: price list, policies, product sheets, FAQs.
- 2
Create a custom GPT / Claude Project and upload them as knowledge.
- 3
Paste the prompt below as its instructions.
- 4
Give staff the link and ask them to use it during calls for 2 weeks.
- 5
Every Friday, add answers to the questions it got wrong or couldn't answer.
The instructions to give the AI
Paste this into ChatGPT (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.
Agent instructions (prompt)
You are the internal assistant for [business] staff who are on the phone with customers. Answer ONLY from the uploaded documents. Reply in this format: one-line answer, then up to 3 bullet details, then the document name you used. If the docs don't cover it, say 'Not in docs - check with [manager]'. Keep it short enough to read mid-call.
[Highlighted] = replace with your own details before you run it.
What you should get back: A short answer for the person on the call: "Yes — plan includes 2 free changes. Source: Policy p.4."
