AI integration with Smily: an intelligent co-host for your property management

What is Smily?

Smily, formerly BookingSync, has established itself as a reference in the vacation rental sector in France and internationally. Founded by Sébastien Grosjean, an entrepreneur steeped in the hospitality industry since childhood, the platform now has employees in 17 countries and manages a business volume exceeding one billion euros.

This all-in-one software combines PMS and channel manager to centralize your rental management. Smily automatically synchronizes your listings across over 1,000 booking sites, including giants like Airbnb, Booking.com and Abritel, as well as partners like Veepee or Cdiscount. The platform prevents double bookings through real-time calendar updates and allows you to manage payments, guest communications, and task planning from a single interface.

Smily users see an average 40% increase in revenue, particularly thanks to multi-channel distribution and dynamic pricing tools. Recognized by Airbnb, Booking.com and Expedia as a preferred global partner, Smily also offers AI features for responding to guest reviews, a comprehensive mobile app, and personalized support.

However, like any PMS, Smily has certain limitations: the learning curve can be steep for new users, rates increase with the number of properties managed, and some advanced features require third-party integrations. This is precisely where an AI channel manager automation solution like Nowistay makes perfect sense.

How to integrate AI with Smily?

Integrating artificial intelligence into your Smily workflow radically transforms your operational efficiency. Unlike traditional connectors that require complex development or intermediate APIs, Nowistay's intelligent co-host adopts a direct and revolutionary approach.

Our AI connects natively to Airbnb and Booking, the two platforms that generate the majority of your bookings. This direct connection means that even if you use Smily to centralize your calendars and reservations, Nowistay communicates in parallel with your listings on these platforms without creating conflicts. You benefit from a double layer of automation: Smily for administrative and pricing management, Nowistay for intelligent interaction with your guests.

Implementation requires no complicated technical installation, no additional app downloads, and no API connector configuration. In just a few minutes, you connect your Airbnb and Booking accounts to Nowistay, and the AI immediately begins managing your guest messages. This simplicity contrasts with traditional integrations that can take several days to set up.

The benefits for your property management are immediate: automated responses to frequently asked questions, personalized welcome messages, proactive management of specific requests about amenities, house rules clearly communicated, intelligent upsell pushes, and post-stay thank you messages. All this 24/7, in multiple languages.

More and more property managers are adopting an AI co-host that reduces time spent on messaging and significantly improves their response rate, a determining factor in Airbnb and Booking's algorithmic ranking.

Key features of Nowistay AI integration with Smily

Intelligent guest messaging management

Nowistay's AI co-host excels at communicating with your guests. Unlike basic automated responses, our assistant uses advanced conversational AI that understands the context and intent behind each message. A guest asking "Is there a hairdryer?" receives a precise answer based on your property's amenities, while a question about "nearby restaurants" triggers personalized recommendations.

The AI handles pre-arrival requests professionally: questions about access procedures, flexible check-in times, luggage storage options, or specific requests like a baby crib. During the stay, it instantly responds to questions about equipment operation, wifi, heating, or recycling rules. After departure, it sends personalized thank you messages and encourages guests to leave a review.

This 24/7 responsiveness is multilingual: French, English, Spanish, German, Italian, and many other languages are automatically detected and processed. No more waiting until morning to respond to an Asian guest who writes in the middle of the night. Your response rate soars, your response time drops below the one-hour mark. Two metrics that Airbnb and Booking's algorithms reward with better listing positioning.

This intelligent management doesn't replace humans but frees them from repetitive tasks. The AI recognizes when a situation requires your direct intervention (such as a technical emergency, complex complaint, unusual request...) and immediately notifies you via email and/or WhatsApp. You maintain control while delegating the essentials.

Simplified multi-platform management

While Smily centralizes your calendars and synchronizes your rates, Nowistay adds a layer of intelligence to cross-platform communication. Our AI knows the specifics of each platform: Airbnb guests don't have the same expectations as Booking guests, and message tone may vary slightly.

The real power lies in the consistency of your digital presence. Whether your guest booked via Airbnb, Booking, or directly on your site, they receive the same quality of service, the same precise information, the same exemplary responsiveness. This uniformity strengthens your brand image and professionalism.

Integration with Smily means all your reservations (whether from Airbnb, Booking, Abritel or other OTAs) automatically benefit from the AI assistant. You don't have to configure each platform separately or worry about updates. Nowistay detects new reservations synchronized in your system and automatically activates AI support for each guest.

This multi-platform approach eliminates a recurring problem for property managers: communication fragmentation. No more messages scattered across different messaging systems, forgotten responses, contradictory information given depending on the platform. The AI maintains contextual memory of each interaction and ensures perfect consistency.

Case studies and testimonials from Smily customers

Parisian property management: from 45 to 15 hours of messaging per week

Sophie, manager of a 28-apartment property management company in Paris, used Smily to synchronize her listings but still spent 45 hours per week responding to guest messages. After integrating Nowistay's AI co-host, this time dropped to 15 weekly hours focused solely on complex situations requiring a human touch.

"The implementation was surprisingly simple," she testifies. "In less than 30 minutes, all my Airbnb and Booking listings were connected. The AI immediately started responding to questions about amenities, public transport, and arrival procedures. Our response rate went from 87% to 99%, and our average response time dropped from 3 hours to 12 minutes."

The impact on her Airbnb ratings was spectacular. Her overall rating went from 4.6 to 4.8 in two months, and several reviews explicitly mention "exceptional responsiveness" and "immediate answers to all our questions." This rating improvement propelled her listings to the top of search results, generating 23% more bookings.

Coastal agency: managing seasonality stress-free

Marc manages about forty vacation rentals in Brittany via Smily. The summer high season represented his annual nightmare: hundreds of daily messages, requests in English, German, Dutch that he had to translate, questions at 10 PM that he could only answer the next day.

Since using Nowistay in addition to Smily, high season feels like normal season. "The multilingual AI handles 80% of messages automatically. German travelers receive responses in German, British guests in English, and all instantly, even at night. My team focuses on the essentials: arrivals, cleaning, maintenance."

His occupancy rate increased from 76% to 89% in off-season, directly linked to his better responsiveness improving his Booking ranking. "The algorithms love us now," he jokes. "Our position in search results has significantly improved, which generates more views and therefore more bookings. It's a virtuous circle."

Digital transformation of a small operation

Émilie owned 5 rural cottages and used Smily to avoid double bookings. But responding to messages took so much time that she was considering abandoning certain platforms. "I was about to remove my Booking listings because I couldn't keep up anymore," she confides.

Integrating Nowistay's co-host transformed her business. "I didn't know you could automate so much without losing quality. Guests don't even realize they're talking to an AI because the responses are so natural and relevant. Some even thank me for my 'exceptional availability.'"

Her service quality improved considerably: no more unanswered messages, complete information automatically sent before each arrival, systematic post-stay follow-up. Her positive review rate went from 82% to 94%, and she was even able to add three new properties without increasing her workload.

FAQ on AI integration with Smily

Is Nowistay AI compatible with all versions of Smily?

Yes, completely. Our AI co-host works in parallel with Smily without requiring direct technical integration with your PMS. Whether you use Smily Service, Smily Business, or Smily Manager, Nowistay connects directly to your Airbnb and Booking accounts, independently of your Smily configuration. This architecture guarantees universal and sustainable compatibility.

What are the immediate benefits after activation?

From the first hours, you'll notice an improvement in your response rate and time. Messages received outside your working hours get instant responses rather than waiting until the next day. Within the first 48 hours, you typically save 70% of the time previously spent on basic messaging. Within two weeks, your Airbnb and Booking metrics visibly improve, positively impacting your algorithmic visibility.

Does AI completely replace human intervention?

No, and that's not the goal. The AI co-host intelligently handles standard and repetitive exchanges that represent 75 to 85% of your messaging: information about amenities, directions, house rules, schedules, local recommendations. It immediately notifies you for situations requiring your attention: emergencies, complaints, unusual requests, special negotiations. You remain in control and intervene where your human expertise truly adds value.

How does multilingual management work?

The AI automatically detects the language of each message and responds in that same language. It masters over 20 languages commonly used in tourism. This capability is particularly valuable for international tourist destinations where you receive messages in English, German, Spanish, Italian, Dutch, etc. No more online translators or approximate responses in a foreign language.

Can I customize AI responses according to my properties?

Absolutely. For each property, you enter the specifics: particular amenities, special rules, local recommendations, unique access instructions. The AI automatically adapts its responses based on the property concerned by each booking. A guest booking your apartment with a terrace will receive different information from one booking your studio without outdoor space, even though both use Smily and receive Nowistay assistance.

Does integration affect my Smily subscription or costs?

No, Nowistay operates independently and doesn't impact your Smily contract or costs. You keep your current PMS subscription and simply add the artificial intelligence layer for guest communication. The two solutions complement each other without overlapping: Smily manages your administrative back-office and synchronizations, Nowistay optimizes your guest relations and responsiveness.

Unlock your property management's potential with native AI

If you're already using Smily, you've chosen a high-performance PMS that efficiently centralizes your operations. By adding Nowistay's AI co-host, you take a new step in optimizing your vacation rental business.
