Yimsai - AI Concierge for your Business

Your place
always ready to answer.

Every guest is greeted with a smile. Yimsai brings that welcome to chat — customers message your restaurant, café, hotel, or shop on WhatsApp, Telegram, or Messenger and get instant, accurate answers from your real data.

Answers at 2 am. Or 2 pm.

An AI agent answers customer questions 24/7 in natural language. It knows your menu, hours, prices, and what other guests have said. Every answer comes from your real data — never invented. When it genuinely doesn't know, it hands off to a human instead of guessing.

What's included

Everything a concierge would know.

One system, one setup. Covers the questions guests actually ask.

Photos on request
Ask "show me the terrace" and the agent sends real photos of your venue and dishes — served from the images you uploaded.
Grounded in real reviews
Your Google reviews, via the Business Profile API, feed the agent. "Is it good for kids?" gets answered from what real guests actually wrote.
Multi-place from day one
Run many venues from one system — each with its own menu, hours, language, booking rules, and personality, isolated from the others.
Safe by default
A pre-agent filter keeps conversations on-topic and stops abuse, with per-user rate limiting. If the AI has trouble, a circuit breaker quietly routes to a human.
Owner self-service
Ask the bot about your own place: "how many bookings tonight," "what prices do I have set." Same chat, private answers.
Update by chat
Send a menu PDF, a photo of the specials board, or a line of text — the agent extracts and structures it. You confirm before it goes live, and every change is undoable.

Languages

Speaks your customer's language.

The agent detects each person's language and replies in it, consistently, across the whole conversation. Built-in support spans 13 languages with an English fallback — a guest who writes in Italian keeps getting Italian.

Reservations

Book a table, straight from chat.

Customers request, change, and cancel from chat. The engine checks real capacity — tables, seating areas, turn times — and confirms instantly or proposes the nearest times that fit. You choose auto-accept or manual confirmation per booking.

Escalation

Human handoff, done right.

When a conversation needs a person, the agent quietly escalates and pings the owner with a one-tap button. The owner chats directly with the customer through the same interface, with full context, then hands back to the AI when done. The customer never knows they were "transferred."

Google Reviews

Real answers from real guests.

Your Google reviews feed into the agent through the official Business Profile API, so questions like "is it romantic?" or "good for families?" get answered from what real guests actually wrote — with semantic search over your full review history.

AI used this to answer:"Great for a romantic evening — guests regularly mention the candlelit terrace and the attentive service when marking special occasions."
