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.

Slang AI Alternative

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

It's important to choose the right Voice AI provider for your niche and your purposes. As a restaurant you don't want to work with an AI receptionist for contractors.

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

Feature Comparison of AI Call Centers for restaurants

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 all major systems including Toast, Square, Clover, Skytab, and Flipdish
  • Direct phone order processing with AI
  • Intelligent upselling based on order content
  • Real-time order entry into your system
  • 24/7 availability with no downtime
  • Multilingual support in English and Spanish (included)
  • 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: same-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.

Restaurant Voice AI Scalability

As order volume grows, Certus AI scales effortlessly, handling multiple simultaneous calls without quality degradation.

How Voice AI Integrates with Your Existing Restaurant Tech Stack

Modern restaurants rely on various technologies to operate efficiently. Understanding how voice AI fits into your existing setup is crucial. As we explored in our guide to restaurant management software vs restaurant voice AI, these systems should complement each other, not create additional complexity.

Certus AI's approach to integration ensures that your restaurant voice AI works seamlessly with your current tools, from POS systems to delivery platforms. This is particularly important when considering the Top 5 Restaurant Technologies that successful establishments are adopting.

Choosing the right Voicebot: Key Questions to ask

When evaluating alternatives to Slang AI and other platforms, consider:

  • Does it actually take orders, or just redirect customers?
  • How well does it integrate with your existing POS?
  • Can it handle your menu's complexity?
  • What happens during peak hours?
  • How does it impact your revenue per call?

Ready to transform your Phone Operations?

The choice between Slang AI and Certus AI comes down to a fundamental question: Do you want a system that answers calls, or one that completes sales?

For restaurants serious about maximizing phone order revenue and delivering exceptional customer experiences, the answer is clear. Certus AI's direct ordering capabilities, POS integration, and intelligent upselling features make it the superior choice for restaurant order automation.
