Set Up Your Call Shield
A simple first-run flow for App Store users. No one needs to understand Twilio or Retell to get protected.
Step 1
What should Gate Keeper protect you from?
Choose the main reason you are setting up the shield. You can change this later.
Step 2
Pick the voice style.
The assistant should sound like someone calm at the front desk, not a chatbot.
Step 3
Who can reach you?
Trusted callers get warmer handling. Everyone else has to explain why they are calling.
Step 4
Set your collector script.
This is the careful message Gate Keeper uses when a collector calls.
Step 5
Connect and test.
For launch, the user sees plain language. Behind the scenes, Twilio routes the number and Retell runs the AI voice agent.
Choose number
Pick a Gate Keeper number or connect call forwarding.
Test call
Practice a collector, spam, business, and trusted caller.
Go active
Turn on call screening and get summaries after calls.
Northstar Recovery called. Gate Keeper requested written communication and did not verify personal information.

What The User Sees
SimpleNo Twilio language. No Retell language. The app says: your shield is active, these calls need review, and here are your next actions.
App Store Screens
NeededCall Inbox
Every call turns into a summary, transcript highlights, and a suggested next step.

Manually log a call while the Twilio + Retell connection is still being built.
Red Flag Alerts
These are moments where the AI should stop negotiating and escalate to the user.
Caller History
Grouped view of repeat callers. This is where the app starts learning who deserves attention and who should be kept outside the gate.

Block List
Numbers or companies Gatekeeper should hard-decline. In the real app, this would sync with Twilio call routing before the AI even starts talking.
Add Block Rule
Blocked Callers
0 activeCall Rules
Choose the words the AI is allowed to use. The assistant should sound calm, but it should stay inside hard boundaries.
Debt collectors
Take caller details, avoid debt admission, request written communication, and never promise payment.
Legal threats
Collect company name and deadline, end calmly, alert the user immediately.
Sales calls
Ask to remove the number from their list, then end the call without debate.
Personal callers
Take a warm message and offer a text summary. Transfer only to approved contacts.
Medical offices
Take appointment details without discussing sensitive medical information.
Unknown callers
Require name, company, reason, and callback number before continuing.

No payment promiseTwilio Role
Twilio supplies the phone number and routes incoming calls to the AI voice service. Think of it as the phone line for the app.
Retell Role
Retell runs the AI voice agent, speaks with the caller, follows the Gatekeeper prompt, and sends back transcripts and call summaries.
Deploy With Twilio + Retell
This turns Gate Keeper into a real phone flow: Twilio owns the number and routing, Retell runs the voice agent and call analysis.
1. Twilio number
Buy or connect a phone number. Configure incoming calls to route to the Retell voice agent endpoint.
2. Retell agent
Create a single-prompt Retell agent, paste the Gatekeeper system prompt, choose a calm voice, and test in the browser first.
3. Call analysis
Ask Retell to extract caller name, company, bucket, urgent flag, reason, tone, and recommended follow-up after every call.

This keeps Claude's original idea, but wraps it with dashboard rules, safer escalation language, and a Twilio + Retell-ready call flow.

These settings are the product's trust layer. They should be visible, simple, and difficult to accidentally weaken.
