What it does

Every guest message, handled the way you'd handle it.

Automate guest messages from Airbnb, Booking.com and your direct bookings: check-in times, WiFi, parking, house rules, stay extensions and arrival guides, all answered from your live booking data in your guest's own language.

Answers in their language

Text in your guest's own language automatically. Voice notes understood in multiple languages, including English, Spanish, Italian, French and German.

Understands voice notes

Guests can talk instead of typing. Voice notes are transcribed and understood automatically in English, Italian, Spanish, French and German.

Reads your real bookings

Connected to the channel manager you already use, so dates, codes and availability are accurate, never guessed.

Learns from you once

If it can't answer, it asks you on WhatsApp and saves your answer, so the next guest is answered instantly, without you.

Self-learning

It only asks once.

When the assistant genuinely can't answer, it doesn't guess. It asks you on WhatsApp, relays your answer to the guest, and saves it to that property's knowledge base, so every future guest gets it instantly and you're never asked again.

01 · GUEST Only factually correct answers "Is there a hairdryer in the apartment?" This information isn't in the knowledge base. The assistant never makes up an answer, it escalates to the host and learns the answer for next time.
02 · HOST It quietly asks you You get one WhatsApp message. You reply once. That's the whole job.
03 · KNOWLEDGE BASE The answer saves itself Your answer goes back to the guest and into the property's knowledge base automatically. "We don't have that" gets saved too.
04 · NEXT GUEST Answered instantly, without you The next guest who asks gets the answer in seconds. You are not involved, and never asked that question again.

From a host
“Before KeySignalAI, I was answering the same WhatsApp questions from guests every single day, check-in times, WiFi passwords, where to park. Now it handles all of that itself, in whatever language the guest writes in, and it only pings me when something actually needs my attention. It's given me hours back every week.”
