Slang AI vs Smith.ai (2026): which should you pick?

Pick Slang AI if

• Fits if you run a restaurant that misses calls during service
• Works for groups that want one phone system across several locations

Look elsewhere if

• Pricey if you have one location: from $399 each, and the billing period is not shown
• Watch out: Superhost, 97 languages, custom branding and cross-selling are all on Premium, $599
• Skip it if you want a trial, as none is published
• Watch out: every plan needs a quote, so the listed price is a starting point

Pick Smith.ai if

• Fits if you get fewer than 25 calls a month and want them answered
• Works for law firms and service businesses that use Clio or Calendly

Look elsewhere if

• Pricey if calls grow, as 75 calls is $150 a month on AI Pro
• Tight if you want a free try with no card, since the Free plan needs one
• Pricey if you want people, because live-agent plans start at $300 a month for 30 calls
• Watch out: the 30-day money-back on human plans excludes overage calls and is capped at $1,000

Slang AI

Reservation handling by phone

The assistant answers calls and manages reservations, with text links and confirmations sent to guests afterward.

Superhost conversations

Premium adds interruptible conversation, automatic switching between 97 languages and a choice of 20 voices with custom greetings.

Answers from approved information

The vendor says the assistant answers from the restaurant's approved information rather than open-ended generation, and that calls are monitored for quality.

Cross-selling across locations

When a guest's first choice is full, the assistant can offer availability at nearby or sister locations in the same group.

VIP routing and alerts

Frequent diners can be routed straight to staff, and real-time alerts about private event inquiries or lost items go to a phone.

Smith.ai

AI call answering

An AI receptionist picks up calls around the clock, screens spam, qualifies callers against criteria the business sets, and routes or transfers them.

Live agents when needed

Hybrid and human-first tiers bring in live North American agents, either for new-client calls or for every call, at higher per-call rates.

Appointment scheduling

The free plan lists AI scheduling with Calendly and similar tools. On the human-first plans, booking an appointment is a per-call add-on at $1.50.

Quality Studio

Lets a business test how the AI handles calls before going live. It is included on the free plan.

CRM and intake integrations

Call details go to a CRM or Zapier, with Clio, Filevine and Lawmatics named. Human-first plans include the first CRM; each extra one costs $0.50 per call.

Add-ons billed per call

Human-first plans price extras per call, such as a dedicated Spanish line at $1.00, call recording at $0.25 and conflict checks at $0.50.
