Can AI Reply to Your Clients on Your Own WhatsApp?
Your assistant answering on the number your clients already message you on — what it can reply with, what you keep control of, and how you connect it yourself.
Yes. PropKaki can run your AI assistant on your own WhatsApp number, so clients who already have you in their chat list get an immediate, grounded answer instead of silence. It is the same assistant as the one on your website, answering property questions from real URA and HDB records, recording what a client is looking for, sharing your listings and booking viewings. Every conversation lands in the same Inbox as your website's, and you keep control over what it does, for everyone or one client at a time. You connect your own number yourself, from the Connectors tab, through Meta's own sign-up.

Your website and its assistant solve a problem you have with strangers. It does nothing for the twenty people already in your chat list, because they will never think to tap a link — they will just message you, at 11pm, the way they always have.
That is what this is for: your assistant answering on your own number, for the clients who already have it. This page covers what it replies with, what stays under your control, and how you connect your number yourself.
Can AI reply to your clients on your own WhatsApp?
Yes. PropKaki can answer on your own number — the same assistant as your website, for the clients who already have you saved.
Yes. The same assistant that runs on your PropKaki website can answer on your own WhatsApp number, so a client who already has you saved gets a grounded reply instead of a read receipt.
The distinction from your website matters. Your website works on people who do not have your number — someone off your Instagram bio, a portal profile, a QR on a name card — and part of its job is collecting a contact. This works on people who already have you, which means there is no link to share, nothing for them to install, and no contact to capture. Its job is coverage: the message that lands while you are in a viewing gets a real answer at the time it was asked.
And you set it up yourself: connect your number from the Connectors tab and switch the assistant on for WhatsApp. How, further down.
Whose WhatsApp is this — and how is it different from you using PropKaki?
This is your clients messaging your number and your assistant replying. You using PropKaki on WhatsApp is a separate thing on PropKaki's number.
PropKaki touches WhatsApp in two completely different ways, and confusing them is easy.
| Whose number | Who talks to it | What it is for | |
|---|---|---|---|
| Your reply assistant (this page) | your own number | Your clients | Answer the message you could not get to |
| Your assistant — your website | none; your free website, at a link you share | Your clients | Catch an enquiry from someone who does not have your number |
| PropKaki on WhatsApp | PropKaki's number, in your WhatsApp | You | Price a listing, run numbers, produce client work |
This page is the first row: your clients, your number, your name on the reply. The third row is you doing your own research, privately, and no client is ever in that thread. Both have their own guides, linked at the foot of this page.
What does it actually reply with?
Grounded property answers from real transaction records, with the working shown — not a deflection or a canned holding message.
It answers the question, which is the entire difference from an auto-reply.
A standard WhatsApp Business away message says you are unavailable. This reads what the client asked and answers it: what a flat in their block has been transacting at, what the stamp duty comes to, whether their timeline works, what the MOP rule actually says. The figures come from real URA caveat and HDB resale records with the period and the count attached, not from a model's recollection.
In Advisor mode it runs the same grounded assistant as your website, so a client gets the same quality of answer whichever way they reached you.
And where it cannot ground something — a specific unit's facing, live remaining units at a launch, today's mortgage packages — it says so and points them to you, rather than inventing a number that arrives under your name.
What else can it do besides answering?
Record what the client is looking for, talk through your own listings, book a viewing or a consultation, and hand you the thread.
Five things beyond the answer, each one a switch you hold:
- Record what they are after — budget, timeline, buying or selling, which area — picked up from the conversation rather than an interrogation.
- Take their contact details when they volunteer them.
- Talk through your own listings, drawn from your verified record rather than invented.
- Book a viewing.
- Book a consultation for the client who wants to talk about their move rather than one unit.
All five arrive switched on by default, and you turn off whichever you do not want. How much it says around them is set by the mode, in the next section.
What stays under your control?
Whether it is on, which mode it runs in — for everyone or for one client — whether it answers anything beyond property, which skills run, and how much it can ever spend.
Five levers, all under Inbox → ⋯ → Configure Assistant:
- On or off. Turn Off stops it answering, immediately.
- Mode. Advisor answers any property question; Secretary collects the client's details and passes them to you; Auto-Reply replies with what you've preset. A new assistant starts on Secretary.
- WhatsApp or not. Answer clients on WhatsApp decides whether it replies on your number at all, separately from your website.
- Property questions only. Turn this on and it declines anything off-topic instead of obliging.
- Spending caps. A daily cap per conversation and a monthly cap across all of them. It stops at your number, not at ours.
On top of that, every message it sends is in your Inbox to read, message by message with the time on it. Nothing happens in your name that you cannot go back and check.
And per person: pick someone in the Inbox, open ⋯ → Configure Assistant → For This Client, and give them their own mode, or press Turn Off to stop it for them alone while it keeps answering everyone else.
Where do those conversations end up?
In the same Inbox as your website, so a client's history does not split across two places.
One Inbox.
Whichever door a client came through — your website, your own WhatsApp number, or the app — the conversation lands in the same place, with the channel marked on it. That matters more than it sounds: if the two were separate, a client who first used your website and later messaged your number would exist twice, and you would be reading half a history in each.
You get the full transcript, timestamped, along with whatever the assistant worked out about what they are looking for.
How do you get it, and what stage is it at?
Yourself: connect your number from the Connectors tab, then switch the assistant on for WhatsApp. It is live for any CEA-licensed agent.
From the app, yourself.
Connecting a business's own WhatsApp number to a third-party assistant runs through WhatsApp's own approval process for providers. Meta approved PropKaki as a WhatsApp Tech Provider on 10 August 2026, so you now connect your number yourself, with no one doing it by hand.
Open Extensions → Connectors, choose WhatsApp and press Connect. Pick the number — the one already in your WhatsApp Business app, or a different number with no WhatsApp on it — and Meta's own sign-up window does the rest. It needs a CEA licence on your account; without one, the button asks you to get verified first.
Then open Inbox → ⋯ → Configure Assistant, switch on Answer clients on WhatsApp and press Turn On. The assistant can only be on while your website is, so turn your page on first under My Page.
Most agents start with the assistant on their website; the number is an addition to it, not a replacement.
What is the biggest mistake agents make with an auto-reply?
Using one that deflects. A holding message tells a client you are unavailable — which is what they already suspected.
The usual auto-reply confirms the fear rather than answering the question.
"Thanks for your message, I'll get back to you shortly" tells a client, at the moment they are deciding whether you are the responsive one, that you are not available. They then message somebody else — not out of disloyalty, but because they had a question and you did not answer it.
The thing worth automating is not the acknowledgement. It is the answer. A client who asks what their flat is worth at 11pm and receives a real figure with the transactions behind it has had their question answered by you, at 11pm, whether or not you were awake for it.
Do your clients need to install anything?
No. They message the number they already have for you, in the WhatsApp they already use.
No. There is nothing for a client to download, no account to create and no link to tap. They message the number they have always messaged. From their side nothing about the conversation is new except that a reply arrives quickly.
Can you take over the conversation yourself?
Yes — you read every message and reply as normal, and you can turn the assistant off for one client while it keeps answering everyone else.
You read every conversation in full and can reply yourself at any time; it is your WhatsApp. To stop the assistant for one specific client, open them in the Inbox, choose ⋯ → Configure Assistant → For This Client and press Turn Off; it keeps answering everyone else. The same tab can give that one person a different mode.
What happens if it does not know the answer?
It says so and points the client to you, rather than guessing.
It declines and hands off. There is a maintained list of things it does not have — a specific unit's facing or view, a launch's live remaining units, today's bank packages, en-bloc speculation — and on those it tells the client it cannot answer properly and points them to you. On a channel carrying your name, an assistant that occasionally says "I don't know" is the only kind worth running.

Methodology and sources
Capabilities and controls are described as currently built. Where something is planned rather than shipped, this page says so instead of implying it.
What this page describes. Running the PropKaki assistant on an agent's own WhatsApp number: what it replies with, the five skills and their default state, the controls available today, where conversations land, and how an agent connects their number.
Defaults. The five skills — recording what a client is after, taking contact details, sharing your listings, booking viewings and booking consultations — are on in a new assistant's configuration and are switched off individually. A new assistant starts in Secretary mode.
Controls. On or off, mode, WhatsApp or not, property-questions-only, and the daily and monthly spending caps apply across the assistant. On or off and the mode can also be set for one client.
Connecting a number. Self-serve through Meta's own sign-up, since Meta approved PropKaki as a WhatsApp Tech Provider on 10 August 2026. It needs a CEA licence on the account.
What this page does not claim. No response-time figure, no number of enquiries handled, no conversion rate, and no comparison against other auto-reply tools.
