Slang AI

Slang AI is a restaurant voice AI that answers incoming phone calls, books reservations and handles guest questions so staff are not pulled away from the floor. Founded in 2019 by two former Spotify data scientists, it focuses on full-service and fine dining restaurants rather than takeout ordering. Its answers come from information the restaurant approves, which keeps it from improvising about hours, menus or policies.

What is Slang AI used for?

Restaurants use Slang AI to pick up every call, including during the dinner rush and after hours, and turn more of them into reservations.

• Booking, modifying and canceling reservations through OpenTable, SevenRooms, Yelp and Resy
• Answering common questions about hours, parking, dress code or menu details
• Sending text links and confirmations to callers
• Recognizing VIP and frequent diners and routing them to staff
• Capturing private event inquiries and sending real-time alerts to managers
• Suggesting open tables at nearby or sister locations when the first choice is full

Who Slang AI is best for

Slang AI suits full-service restaurants and hospitality groups that take many reservation calls, from single upscale venues to multi-location groups. It is especially useful where hosts are busy seating guests at peak times. Quick-service and pizza shops whose calls are mostly takeout orders may be better served by a phone ordering tool connected to their POS.

Slang AI pricing

As of October 2026, Slang AI lists Core starting at $399 per location, with reservation management, text confirmations, reservation insights, full reservation integrations, VIP handling and bilingual support. Premium starts at $599 per location and adds the Superhost voice, 97 languages, custom branding, enterprise quality assurance, reservation cross-selling, private events capture and real-time alerts. Enterprise pricing is custom, with custom workflows and integrations, reporting and dedicated support. The pricing page does not state the billing period, so confirm terms when you request a quote.

Limitations to keep in mind

• Pricing is per location, which becomes significant for large groups
• The most natural voice and broad language support sit in the Premium plan
• It is focused on reservations and guest questions, not phone ordering and payments
• Answers are only as current as the information you keep updated

Slang AI vs alternatives

echowin and DialNexa are general AI voice agent platforms that can be cheaper for businesses that want to build their own call flows, but they lack native reservation integrations. Kalyvox is a simpler AI receptionist for small businesses that screens and transfers calls. GirikVoice suits businesses needing real-time language detection across many call types. Slang AI wins for full-service restaurants that want reservations booked directly into OpenTable, Resy or SevenRooms by a voice agent built for hospitality.

Tips for getting started with Slang AI

Before setup, write down the twenty questions your hosts hear most often and make sure each has an approved answer. Connect your reservation platform first so bookings land in the right system. Decide which callers should always reach a person, such as large parties or VIPs. Review call summaries weekly in the first month to spot gaps in your restaurant information.
