An AI agent takes over sales admin and saves each rep 35+ hours a month
In plain words
A Reddit builder shared an agent that logs calls, updates deal fields and writes follow-ups in the CRM so reps don't have to.
What happened: 35+ hours saved per rep each month, and 22% more deals closed (their own figures).
These numbers come from the builder and haven't been checked independently.

How to do it yourself
Our suggested steps. The company didn't publish theirs.
- 1
Record or transcribe sales calls (Fathom, Otter, Zoom).
- 2
Send each transcript to ChatGPT via Zapier with the prompt below.
- 3
Map its JSON output to CRM fields (stage, next step, amount).
- 4
Create the follow-up task and draft email automatically.
- 5
Have reps spot-check for two weeks.
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.
This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.
Agent instructions (prompt)
From this sales call transcript, return JSON: {deal_stage, budget, decision_maker, pain_points, objections, next_step, next_step_date, follow_up_email (80 words)}. Use null if not mentioned.
[paste][Highlighted] = replace with your own details before you run it.
What you should get back: {"deal_stage":"proposal","budget":"$20k","decision_maker":"COO","pain_points":["slow quotes"],"next_step":"demo Fri"}
