Who each is for
Smith.ai is for businesses that want an answering service rather than a phone app, with North America-based live receptionists, an AI receptionist, or both. It bills per call: the AI plans start with a free plan for 25 calls a month, and live receptionists start at $300 a month for 30 calls. It books through AI Scheduling with Calendly and more, and you can use a dedicated number or port yours. If you need live people or detailed intake for a law firm or agency, it’s built for that.
2Line.AI is for owners who want the number, their own calls and texts, and an AI receptionist in one app. Mia answers in your business name, books inside your hours and leaves a slip, and you call and text customers back from the same number. You pay one plan plus credits for the minutes Mia actually talks, instead of buying a set number of calls.
What a typical day looks like with each
With Smith.ai
A small law office has Smith.ai answer its calls. Every caller reaches a receptionist, live or AI, who works through the office’s intake questions and books consultations. Each answered call counts toward the monthly plan, so the office picks a plan size that fits a normal month, and pays per call above it on the live plans.
With 2Line.AI
A solo locksmith on 2Line.AI gets most calls while driving or working on a lock. Mia answers with the business name, asks where the caller is and whether they’re locked out right now, and hands the urgent ones straight to you. Routine rekeys get booked inside your hours. You call or text back from the same app, on the same number customers already have.
Choose 2Line.AI if
- You want the number, texting and AI receptionist in one app at a flat plan price
Smith.ai may fit better if
- You need live human receptionists or intake scripts for a law firm or agency
- You want per-call rather than per-minute pricing
Switching from Smith.ai to 2Line.AI
- Pick a new local number in 2Line.AI from the area codes near you. Porting isn’t supported, so this is a new number, not your Smith.ai number moved over.
- Set your business name, hours and caller ID name (up to 15 characters). Teach Mia from your business name or website, then call the new number from another phone to test her.
- Keep Smith.ai running while you switch, so anyone who still has the old number reaches you. A month or two of overlap is a sensible minimum.
- Tell your customers. Text your regulars from the new number, and change the old number’s voicemail greeting to give the new one.
- Update your Google Business Profile (Edit profile, then Contact, then Phone number), then your website, Apple Maps, Yelp, Facebook, cards and truck.
- When calls to the old number have slowed to a trickle, cancel Smith.ai.
2Line.AI can’t take over the number your callers use to reach Smith.ai today, so give customers the new number before you cancel. Step-by-step help for Google is in our guide to changing your Google Business Profile phone number.
What 2Line.AI doesn’t do
Worth knowing before you choose:
- No human receptionists. Mia is an AI receptionist; she hands urgent calls to you.
- No number porting. You get a new local US number; you can’t move an existing number in.
- No CRM, Google Calendar or Zapier integrations. Bookings sync to your iPhone Calendar, and leads and slips live in the app.
- No international numbers or calling. Numbers are US only, for calling and texting US numbers.
- Calls, texts and Mia aren’t bundled into the plan; they use credits. At zero credits they pause until you add more, and your number stays yours.
