Slang.ai review

Slang.ai is the most reservation-focused product in this list. Guests can make, change or cancel bookings by phone on OpenTable, Yelp and SevenRooms, and when the first choice is full, Slang suggests tables at nearby or sister locations. Its Superhost voice handles interruptions and topic changes, offers 20 premium voices, and on Premium detects and switches between 97 languages mid-call. Slang says its prompts come from studying more than 35 million guest calls, and answers are limited to the restaurant's approved information. Follow-up work lands in a Priority Queue sorted by smart tags, with call recordings, summaries, transcripts and real-time alerts for private event inquiries or lost items. Pricing is public but high: Core starts at $399 per location and Premium at $599, both through a quote. For takeout, Slang texts ordering links instead of entering orders into the POS, which matters for counter-service restaurants.
