Running a restaurant during peak times means juggling countless tasks while the phone rings endlessly in the background.
You've probably heard about voice AI solutions that promise to handle those calls, but not all restaurant phone systems deliver the same results. If you're considering Slang AI or looking for alternatives, this comparison will help you understand why many restaurants are making the switch to Certus AI.
TLDR
Certus AI stands out as the best alternative to Slang AI by offering complete POS integration, direct phone ordering capabilities, and intelligent upselling features.
While Slang AI redirects callers to text links for online ordering, Certus AI processes orders directly during the call, preventing customer drop-offs and maximizing revenue opportunities. This fundamental difference has led numerous restaurants to switch from Slang to Certus for better functionality and higher order volumes.
Why Restaurants need the best AI phone ordering system
The restaurant industry loses billions in revenue annually from missed and mishandled phone calls. Whether it's during rush hours, staff breaks, or after closing time, every unanswered call represents lost business. This is where an AI phone agent for restaurants becomes essential.
Voice AI technology is a lot more than simple call answering.
Modern solutions can:
Handle multiple calls simultaneously
Take complete orders
Answer customer questions
Make reservations
Process special requests
But not all voice AI platforms are the right choice for your restaurant.
Slang AI vs Certus AI: How Orders get processed
Slang AI's Approach
Slang AI focuses primarily on answering frequently asked questions and basic call automation. When it comes to taking orders, their system:
Sends customers a text message with a link to order online
Redirects callers away from the phone conversation
Requires customers to complete additional steps
Creates friction in the ordering process
Certus AI's direct Integration Advantage
Certus AI takes a fundamentally different approach with complete POS integration:
Direct order processing: Orders are taken and submitted during the phone call
No redirects needed: Customers get what they called for – placing an order by phone
Seamless experience: The entire transaction happens in one conversation
Immediate confirmation: Customers receive instant order confirmation
Why choosing the right Restaurant Voice AI matters
The difference between redirecting customers and directly processing orders impacts your restaurant's revenue significantly. Here's what restaurant owners discovered after switching:
Customer Drop-Off Rates
When customers call to place an order, they want immediate service. Asking them to hang up and complete their order through a text link creates friction:
Many customers ignore the text message
Others find the extra steps frustrating
Some simply call a competitor instead
Lost Upselling Opportunities
Another major advantage of AI for restaurants is the ability to increase average order values through intelligent suggestions. But this only works when the AI can actually process the order:
Certus AI: Suggests complementary items during the conversation
Slang AI: No upselling possible when redirecting to text links
Revenue Impact
Restaurant owners report measurable differences in order volume and revenue after switching platforms. The ability to complete orders directly translates to:
Higher conversion rates from calls to orders
Increased average order values
Better customer satisfaction scores
More repeat customers

Core Capabilities of Restaurant Voicebots
Both platforms handle basic functions like answering calls and responding to FAQs.
However, the similarities end there:
Certus AI Features:
Full POS integration with 5+ major systems
Intelligent upselling based on order content
Real-time order entry into your system
24/7 availability with no downtime
Multilingual support in 10+ languages
Live metrics dashboard
Reservation management
Slang AI Features:
FAQ answering
Basic call routing
Text message redirection for orders
Limited integration capabilities
Restaurant Voice AI Integration and Setup
The setup process and integration capabilities differ between platforms:
Certus AI: 3-day implementation with full POS integration
Slang AI: Limited integration options, primarily focused on SMS capabilities
Real-World Performance: What Restaurant Owners Experience
Restaurants using Certus AI are seeing impressive results:
3X increase in delivery revenue on average
45% decrease in time spent answering phones
Average savings of $9,051 per month
Zero missed orders during peak hours
These results come from the fundamental difference in how each platform handles customer calls. When customers can complete their entire order in one seamless conversation, they're more likely to follow through with their purchase.
Making the Switch: Why Restaurants choose Certus
Restaurant owners who've switched from Slang AI to Certus AI as their Restaurant Voice AI consistently cite these reasons:
Functionality that matches Customer Expectations
Customers calling a restaurant expect to place an order over the phone. They don't want to:
Navigate to another platform
Type out their order on a small screen
Wonder if their order went through
Revenue Recovery
Every redirected customer represents potential lost revenue. Certus AI ensures that when someone calls ready to order, the sale happens immediately.
Staff Efficiency
With Certus handling complete orders, staff can focus on in-person customers and food preparation rather than managing complications from incomplete phone orders.
Scalability
As order volume grows, Certus AI scales effortlessly, handling multiple simultaneous calls without quality degradation.
