FAQ

The questions every owner asks before signing up

No. Linewarden texts in plain, friendly English under your business name. It never identifies as an AI. If a customer asks directly, it says "I help cover the front desk after hours" — true and disarming. We do not use synthetic voice on calls; SMS only.

Emergency keywords (burst pipe, gas leak, no heat, fire, flooding, etc.) trigger an immediate SMS to your phone with the customer's name, address, and problem. The AI tells the caller you'll call back within 15 minutes — and you decide whether to dispatch tonight or schedule first thing.

Yes. We integrate with Cal.com and Google Calendar. Linewarden only offers slots you have available, and adds the booking with the customer's name, address, and problem in the description.

Answering services are $0.85-$1.50 per call, charge for transfers, can have 30+ second hold times, and the script never adapts to your trade. Linewarden is $149 flat, replies in 8 seconds via SMS (which customers actually prefer for non-emergencies), and is custom-tuned to your trade.

We don't try to replace your phone tree. We handle the calls you missed, where the alternative was voicemail or losing the lead entirely. That's where the money is.

Seven minutes. You add a forwarding rule on your existing business line (we give you the exact carrier instructions for AT&T, T-Mobile, Verizon, Spectrum), connect your calendar, tell us your trade and service area, and you're live.

You'll see your recovered-revenue dashboard before any charge. If Linewarden didn't recover at least 3× its cost in those 14 days, email us and we'll extend the trial another 14 days at no charge.

No. Linewarden sits behind your existing line via call forwarding. You don't change your number, your carrier, or anything else.

The next missed call could be a $1,200 job.

Or it could be Linewarden handling it for you. Try free for 14 days — if you don't recover at least 3× your subscription, we'll extend the trial another 2 weeks.
