Standalone product
Set up an AI assistant that answers your phone when you can't
A complete setup kit for building an AI phone assistant on your own Twilio number: the call-agent instructions, the intake worksheet that makes it sound like your business, call flows, handoff rules for urgent calls, and a step-by-step Twilio guide.
Read this first. This is a downloadable setup kit, not a phone service. We don't host a phone line, and no calls are placed or answered by Mainstreet.AI. You build it on your own Twilio account and your own AI provider account, and you keep full control of both.
AI Phone Assistant Setup Kit
Set up an AI assistant that answers your phone when you can't.
$100one-time
- AI call-agent instructions
- Business intake worksheet
- Call flows and scripts
- Lead capture and urgent-call handoff rules
- Twilio setup guide
- Testing checklist
- Ongoing-cost disclosure
Sold on its own. It is not part of Starter or Complete, and buying it doesn't include the skill library. See those separately.
What has to happen before it answers a call
Nothing answers your phone the moment you buy this. It answers once you have done all four of these — the kit walks you through each one, but the work is yours.
- 1You create a Twilio account and buy a phone number from Twilio
- 2You connect your own AI provider account
- 3You work through the setup guide and complete the configuration
- 4You run the testing checklist and confirm it behaves the way you want
Allow about an hour for setup, plus testing time. We'd rather tell you that now than have you find out after paying.
What's in the kit
Seven documents plus a start-here guide. Everything is plain markdown you can read, edit, and keep.
AI call-agent instructions
The complete instruction set that tells the AI how to answer, what it may and may not say, how to stay in your voice, and when to stop talking and hand off to a person.
01-ai-call-agent-instructions.md
Business intake worksheet
Fill this in once. Your services, hours, service area, pricing rules, what counts as an emergency, and how you want to be reached. Everything else in the kit reads from it.
02-business-intake-worksheet.md
Call flows and scripts
Written flows for the calls you actually get: a new job enquiry, an existing customer, a price question, a complaint, a wrong number, and an after-hours emergency.
03-call-flows-and-scripts.md
Lead capture and urgent-call handoff rules
What to collect on every call, and the explicit rules for when the assistant must stop and get a human — including the safety cases where it should never try to handle the call itself.
04-lead-capture-and-handoff-rules.md
Twilio setup guide
Step by step, in plain English: create the account, buy a number, connect it, point it at your assistant, and go live. Written for someone who has never used Twilio.
05-twilio-setup-guide.md
Testing checklist
The calls to make before you let it answer a real customer, what a correct result looks like for each, and what to fix when it isn't.

Ongoing-cost disclosure
Exactly who charges you for what, how to see your spend, and how to cap it before it surprises you.

Ongoing costs
You pay Twilio and your AI provider directly. We never bill you for usage.
The kit is a one-time purchase. Running a phone assistant costs money every month, and that money goes to Twilio and to your AI provider, not to Mainstreet.AI. Twilio charges for the phone number and for every minute of calls; your AI provider charges for the speech and language processing on each call. Those rates are set by them and change over time, so we don't quote figures we can't stand behind — check their current pricing pages before you commit.
| Who | Charges you for | Billed |
|---|---|---|
| Twilio | Monthly phone number rental, plus per-minute charges for calls | Billed by Twilio, on your own account |
| Your AI provider | Per-minute or per-token charges for handling the conversation | Billed by that provider, on your own account |
| Mainstreet.AI | One-time $100 for the kit. Nothing after that. | No subscription, no usage fees, no markup on anyone else's charges |
What you need
- A Twilio account and a phone number bought from Twilio (you set this up)
- An account with an AI provider that supports voice conversations
- About an hour for the initial setup, and a willingness to test it properly
- A card on file with Twilio and your AI provider for their usage charges
Don't buy this if
- You want someone else to run the phone line for you — this is a build-it-yourself kit
- You aren't willing to create and pay for a Twilio account
- You need it answering calls today without testing it first
