A voice AI phone agent built specifically for restaurants, priced per location.
The short answer
Slang.ai is purpose-built for restaurants and integrates natively with reservation platforms like OpenTable and SevenRooms. Asisto is built for appointment-driven businesses across many industries, so a restaurant should look hard at Slang.ai first and at Asisto if it runs anything beyond a dining room.
This is the one comparison where the honest answer is often "not us". If you run a full-service restaurant and live inside OpenTable or SevenRooms, Slang.ai speaks that language natively and Asisto does not. Where it stops making sense is everything either side of the dining room - a group with a catering arm, an events business, a venue booking private hire, or an owner running several different concepts. Slang.ai prices per location and stays inside reservations. Asisto covers a wider set of jobs on one line.
