The business below is our own idea for solving this problem, not a company described in these posts.
Who it’s for
Busy professionals, parents and small business owners tired of unknown-number calls.
Adapt it to your industry
Start with one city, niche or customer type, then expand.
Ask your first 10 customers what they would pay before you build more.
Keep a human check on anything that is sent in a customer’s name.
Step by step
List the top spam call types your customers hate (car warranty, loans, fake IRS).
Pick a phone/SMS API that can answer, record a short IVR and text you a summary.
Write the AI script: greet, ask name and reason, hang up on obvious robocalls, forward real humans.
Start with yourself and 5 friends as beta users.
Sell a monthly plan on a one-page site with Stripe.
Never sell or misuse call audio; say so in plain words.
Ready-to-copy prompt
Write a short phone script for an AI that answers unknown calls for me: greet politely, ask who is calling and why, end the call if it is a robocall or sales pitch, and text me a one-line summary only when a real person needs me.
Start with AI
Opens the AI with this guide and the prompt filled in.
