SmartLine

Your US Phone Number with a Personal Assistant

Your AI assistant answers every call, screens every caller, and sends you only what's worth your time.

The Thesis

Every call you answer costs you an hour of deep work. Every call you miss costs you a lead.

Founders were never meant to be receptionists. But every phone system ever built assumed you should answer.

We disagreed. The phone call is the last interruption-first communication tool left. Email became async. Slack became async. Meetings became optional. The phone never changed.

Until now.

SmartLine is the first business number built for founders who don't answer. It works from anywhere. Any country. Any timezone. Your US number follows you — Palma, Bangkok, Singapore, wherever you dock next.

Your AI PA answers every call. A world-class assistant that screens, qualifies, and handles — the way only the best human assistants ever could.

You get the summary. You decide what's worth your time.

You get the signal. Never the noise.

FAQ

How does the NoSmartmadLine AI Assistant screen my calls?+
When a call comes in, the AI answers on your behalf. It asks for the caller's name and purpose of the call. If it's a known contact or an urgent matter, it records a summary and sends it to you via text.
Does this replace my primary phone number?+
No. NoSmartmadLine acts as a "buffer" second number. You can give it to people you don't fully trust yet, use it for public listings, or for "deep work" mode where your primary line is muted.
Does the SmartLine AI sound like a robot?+
No. SmartLine uses advanced natural language voice synthesis to ensure your callers have a professional, human-like interaction. The AI is designed to be polite and efficient, sounding more like a high-end virtual assistant than an automated menu.
What happens if the caller has a complex request the AI can’t handle?+
The AI is programmed to recognize its limits. If a request is too complex, the assistant will professionally ask for a detailed message and a callback number, providing you with a structured summary so you can follow up with the full context.
Can I forward my existing number to SmartLine?+
You don’t need to change your primary number. You can simply set up conditional call forwarding (e.g., when you’re busy or unreachable) to your SmartLine number, and our AI will step in to screen those calls seamlessly.
How does SmartLine handle international time zones?+
This is where SmartLine shines for founders. You can set "Deep Work" hours based on your local time. Even if clients call from a time zone 10 hours away, the AI will handle the call professionally, allowing you to sleep or focus without being interrupted by a ringing phone.
