AI Chatbots

Chatbots that answer, qualify
and book — around the clock

We build AI assistants for your website, WhatsApp, Instagram and Messenger. Trained on your own content, connected to your CRM, and quick to hand the chat to your team when a person should take over.

What we build

A chatbot that does real work,
not just small talk.

We build assistants that answer the questions you get every day, turn chats into qualified leads and bookings, and know when to pass the conversation to your team.

Qualifies every lead

Asks your questions — needs, budget, timing — saves the answers to the lead and routes the hot ones to the right person.

Answers from your own content

Trained on your website, FAQs, policies and catalogue — so replies are about your business, day or night.

One assistant, every channel

The same knowledge and rules on every channel you switch on — and every chat lands in one inbox.

  • Books appointments

    Offers real time slots from your calendar and confirms the booking by message.

  • Sends product and listing matches

    Pulls items from your catalogue or listings that fit what the customer just asked for.

  • Collects details and files

    Gathers names, numbers, emails and documents through quick in-chat forms, and saves them to the lead.

  • Logs everything to your CRM

    Every conversation, lead and booking is saved to your CRM automatically. No copy-paste.

  • Arabic, English and more

    Replies in the customer’s language, including Arabic and English, in your brand’s tone.

  • Follows up and reminds

    Sends booking reminders and follow-up messages, so quiet leads get a timely nudge instead of going cold.

Human hand-off

Hands off to a person — with the whole story.

A good chatbot knows its limits. When a person should step in, the chat moves to your team with the conversation, the answers it collected and the lead details already attached.

  • You set the rules: hot lead, complaint, or a question it can’t answer
  • The right person is assigned by your routing rules
  • The customer never has to repeat themselves

Chat flows

Flows you can see, test and change.

We map each conversation as a flow — ask, branch, send matches, offer times, assign, hand over. Build it step by step on a visual canvas, or describe it in plain words and let AI draft it for you to review. Every flow is tested before it goes live.

How it works

From first call to a live assistant

Five clear steps. The timeline depends on your channels, languages and integrations — we agree it with you in your proposal before any build starts.

Step 1

Map the conversations

We list the questions you get every day, the channels they come in on, and when a person should step in.

  • Top questions and intents
  • Channels and languages
  • Hand-off and escalation rules

Step 2

Train it on your business

We load your website, FAQs, policies, price lists and catalogue or listings, and set the tone of voice.

  • Your content, not guesses
  • Your brand’s tone in each language
  • Clear limits on what it won’t answer

Step 3

Build flows and connect tools

We build the chat flows and connect your CRM, calendar and inboxes, so chats turn into leads and bookings.

  • A flow for each type of conversation
  • CRM, calendar and email connections
  • Lead routing and assignment

Step 4

Test before launch

We run real questions through it, tricky ones included, in every language, and tune answers with your team.

  • Practice conversations
  • Arabic and English checks
  • Your sign-off before go-live

Step 5

Launch and keep improving

We go live on the channels you chose, then read real transcripts and refine the answers with you.

  • Roll-out channel by channel
  • Regular transcript checks
  • Ongoing support as agreed in your proposal
Channels & integrations

Wherever your customers message you.

One assistant across every chat channel, connected to the tools your team already uses. If there’s no ready-made connector, we build the integration.

  • Channels

    Website chat widget, WhatsApp, Instagram and Facebook Messenger.

  • Where the data goes

    Your CRM, Google or Microsoft calendar and email, Slack alerts.

  • Anything else

    Your Shopify store, booking system or internal tools via Zapier, API and webhooks.

FAQ

Chatbot questions, answered

The things clients usually ask before we start. Something else on your mind? Ask us directly.

Your website chat widget, WhatsApp, Instagram and Facebook Messenger. One assistant can run on all of them with the same knowledge and rules, and every conversation lands in one place — your inbox or CRM.

Your own material: website pages, FAQs, policies, price lists, product catalogues or property listings. We set clear limits so it sticks to your information and says so when it doesn’t know, instead of guessing.

You decide the rules — for example a hot lead, a complaint, or a question it can’t answer. The chat moves to the right person on your team with the full conversation and the details collected so far, so the customer never has to repeat themselves.

Yes. It replies in the customer’s language, including Arabic and English, in your brand’s tone. We test each language with your team before launch.

Yes. Conversations, leads and bookings are logged into your CRM, and appointments are offered from real availability in your calendar. If you don’t have a CRM yet, we can build one around your sales process — Propvexa, our real estate CRM, is one we built from scratch.

A WhatsApp Business account connected through Meta’s official business platform. We guide you through the setup and verification. Meta’s messaging policies and per-message fees apply; they’re billed by Meta (or your WhatsApp provider), not by us.

It depends on the channels, languages and integrations involved. After a short call we send a proposal with the scope, a timeline and a clear quote.
