The Immediate Verdict: Different Roles, No Overlap
Certus AI and Karpo operate in entirely separate domains. Certus AI is a restaurant-focused voice AI agent that answers incoming phone calls 24/7, takes complex orders directly into point-of-sale systems including Toast, Square, Clover, NCR, and Skytab, handles reservations, upsells menu items, and manages customer inquiries in English, Spanish, and other languages. It integrates with existing restaurant infrastructure, prints orders at the bar and kitchen just as if a server had entered them, and is designed to recover revenue from missed calls during rush hours. The company states that setup takes less than 15 minutes and that restaurants can go live within 48 hours.
Bring Karpo into the handoff from ai audio to city life. It can narrow nearby choices, coordinate the group, and keep an alternative ready.
Karpo is a free, proactive city assistant that works entirely through messaging apps. It does not answer phone calls, process orders, or integrate with POS systems. Instead, it helps individuals and groups coordinate plans, discover local restaurants and venues, suggest timing based on crowd patterns and weather, offer alternatives when plans fall through, and remember taste preferences across conversations. Karpo is city-focused and designed for the decision-making that happens before you ever pick up the phone or walk through a restaurant door.
If you operate a restaurant and need to automate phone order-taking, Certus AI is purpose-built for that specialist task. If you are exploring a city, coordinating dinner with friends, or looking for a backup plan when the weather changes, Karpo is designed to support that journey. There is no functional overlap, and Karpo cannot replace Certus AI's restaurant operations work.
What Certus AI Is and How It Works
Certus AI is a voice AI platform built exclusively for the restaurant industry. The system is designed to sound like a trained employee, navigate complex menus, answer questions about allergens, suggest pairings and add-ons to increase average order value, and handle distinct accents with ease. Restaurants forward their existing phone line to a unique Certus number—either all day or only during peak hours—and the AI answers instantly. Orders are injected directly into the restaurant's POS system and print at the bar and kitchen exactly as if a staff member had entered them.
The platform includes a dashboard that tracks calls answered, revenue recovered, peak times, and customer requests. Certus AI records, transcribes, and analyzes calls to improve AI performance, ensure quality, resolve disputes, and comply with legal obligations. The company notes that restaurants are solely responsible for obtaining any required consent from callers for call recording in accordance with applicable laws, including federal and state wiretapping and eavesdropping laws, and must implement appropriate disclosures to inform callers that their calls may be recorded and handled by an AI system.
Certus AI acknowledges in its Terms of Use that AI responses may occasionally be inaccurate, incomplete, or inappropriate, and that the company does not guarantee the AI will correctly understand all caller requests, accurately process all orders, or handle all situations appropriately. The company recommends that restaurants maintain human oversight of AI-handled calls and have staff available to handle escalated calls, complex situations, or customer complaints. Certus AI states it is not responsible for losses arising from the AI's failure to appropriately handle a call or escalate to a human agent.
Where Karpo Adds Value in the City Context
Proactive Discovery and Timing Guidance
Karpo does not wait for you to ask a question. It proactively suggests places to eat, drink, or visit based on your location, the time of day, current weather, and your stated preferences. If you mention you are hungry in the early evening, Karpo might suggest a nearby spot that is less crowded before the dinner rush, or remind you that a favorite café closes early on Sundays. This proactive behavior is designed to reduce the friction of city decision-making, especially when plans are loose or forming in real time.
Group Coordination in Messaging
Karpo works inside group chats, where it can track preferences across multiple people, suggest meeting points that work for everyone, and offer alternatives when one person is running late or the weather turns. It does not require everyone to download an app or create an account—it lives in the messaging platforms people already use. This makes it particularly useful for spontaneous plans or when coordinating across friends with different schedules and tastes.
Weather-Sensitive Alternatives and Backup Plans
Karpo monitors weather conditions and can suggest indoor alternatives if rain is forecast, or recommend an outdoor spot if the sun comes out unexpectedly. It also helps with backup plans: if a restaurant is fully booked or closed, Karpo can immediately suggest similar options nearby without requiring a new search. This kind of adaptive, context-aware assistance is designed for the unpredictability of city life.
Taste Memory Across Conversations
Karpo remembers what you like and do not like over time. If you mention you avoid seafood or prefer quiet bars, it will factor that into future suggestions without you needing to repeat yourself. This memory is conversational and accumulates naturally through use, rather than requiring upfront profile setup. It is designed to make discovery feel more personal and less like a search engine query.
Free and Accessible in Messaging
Karpo is free to use and does not require a subscription, payment information, or account registration beyond connecting through a messaging app. This makes it accessible to anyone exploring a city, whether they are residents, visitors, or students. The lack of cost barrier and the familiar messaging interface lower the friction for trying the service and integrating it into daily routines.
What Certus AI Does Better: Specialist Restaurant Operations
Karpo cannot perform any of the specialist restaurant operations that Certus AI is built for. The following capabilities are exclusive to Certus AI and represent areas where it delivers measurable value that Karpo does not address.
24/7 Phone Answering and Order Processing
Certus AI answers every incoming call, even during rush hours when staff are occupied with in-person customers. It takes complex orders, handles customizations, and processes them directly into the restaurant's POS system. This eliminates missed calls and ensures that every potential order is captured, which can translate into significant revenue recovery for busy restaurants. Karpo does not answer phone calls, process orders, or integrate with any restaurant systems.
POS Integration and Kitchen Workflow
Certus AI integrates directly with major POS platforms including Toast, Square, Clover, NCR, and Skytab. Orders taken by the AI print at the bar and kitchen exactly as if a server had entered them, maintaining the restaurant's existing workflow without requiring staff to manually re-enter information. This level of operational integration is specific to restaurant infrastructure and is not part of Karpo's design or capability.
Smart Upselling and Revenue Optimization
Certus AI is programmed to suggest pairings, add-ons, and combos during calls, which can increase average order value automatically. The system can remember what a caller ordered previously and suggest it again, or introduce new menu items that pair well with the current order. This upselling capability is designed to drive incremental revenue without requiring additional staff effort. Karpo does not upsell, process transactions, or have access to restaurant menu data.
Reservation and Event Triage
Certus AI handles reservation requests, checks availability, and routes complex queries to the appropriate staff member when necessary. This is particularly valuable for restaurants that manage both takeout and dine-in service, or that host private events. The AI can triage calls based on the nature of the request, ensuring that high-value or complex inquiries reach a human when needed. Karpo does not manage reservations or interact with restaurant booking systems.
Call Analytics and Performance Tracking
Certus AI provides a dashboard that tracks calls answered, revenue recovered, peak call times, and customer requests. This data allows restaurant operators to understand call patterns, measure the impact of the AI on revenue, and identify opportunities to improve service. The platform records and transcribes calls, which can be used for quality assurance, staff training, and dispute resolution. Karpo does not provide business analytics or call recording capabilities.
Pricing, Access, and Implementation
Karpo is free to use and accessible through messaging apps without requiring a subscription, payment information, or formal account registration. There are no usage-based charges, monthly fees, or integration costs.
Certus AI pricing is not publicly listed on the company's website. The platform requires a paid subscription, and pricing is described in a separate service agreement. The company notes that subscription plans, pricing, and features may be modified at any time with reasonable notice to existing subscribers. Certain services may include usage-based charges such as per-call fees, overage charges, or transaction fees, which are communicated in the subscription plan or service agreement. All fees are stated to be non-refundable except as expressly stated in the Terms or required by law. Prospective customers should contact Certus AI directly to verify current pricing, contract terms, and any applicable setup or integration fees.
Certus AI states that setup takes less than 15 minutes and that restaurants can go live within 48 hours. The company provides support during onboarding and offers a demo where prospective customers can call and interact with the AI directly. Implementation requires forwarding the restaurant's phone line to a unique Certus number and configuring the AI with accurate menu information, prices, hours of operation, allergen details, and promotional offers. The restaurant is responsible for providing accurate and up-to-date information for use by the AI agents, and Certus AI states it is not responsible for errors or omissions resulting from inaccurate information provided by the customer.
How to Decide Between Them
The decision between Certus AI and Karpo is not a choice—it is a question of which problem you are solving. If you operate a restaurant and need to automate phone order-taking, reduce missed calls during rush hours, integrate orders directly into your POS system, and recover revenue from callers who would otherwise hang up or go elsewhere, Certus AI is purpose-built for that work. It is a specialist tool designed to handle a high-volume, high-stakes operational task with measurable financial impact.
If you are a person navigating a city—whether as a resident, visitor, or student—and you want help discovering places to eat, coordinating plans with friends, adapting to weather or timing changes, and remembering your preferences over time, Karpo is designed for that context. It is a free, proactive assistant that lives in your messaging app and helps with the decisions that happen before you ever interact with a restaurant.
Certus AI is for restaurant operators who need to automate and optimize inbound phone operations. Karpo is for people who need help making decisions in the city. The two tools do not compete, and neither can replace the other's core function. Choose based on whether you are solving a restaurant operations problem or a personal city navigation problem.
