Website chat assistant, WhatsApp agent, or both: which a small business needs, and how the two work together
A website chat assistant and a WhatsApp agent sound like the same thing in two places. They serve different moments. The website assistant talks to a stranger who is still deciding; the WhatsApp agent talks to a person who has decided to talk to you. Whether you need both depends on where your customers are when they have questions.
Quick answer
A WhatsApp agent answers people who already chose to message you: known number, clear intent, booking in the chat. A website chat assistant answers anonymous visitors who are comparing and would leave rather than open WhatsApp; its job is to answer in a sentence and convert to a booking or a WhatsApp handoff. If most enquiries start on your website, you need both. If customers find you on Google Maps, Instagram or referrals and message directly, WhatsApp alone may be enough. Both are included on every ReplyKit plan.
What each does
| Website assistant | WhatsApp agent | |
|---|---|---|
| Who | Anonymous visitor, comparing | Known contact, decided to talk |
| Moment | Before choosing you | After choosing to ask |
| Reply style | One to three sentences | Conversational, can be longer |
| Goal | Answer, then book or hand to WhatsApp | Answer, qualify, book, follow up |
| Follow-up | None unless a contact is captured | Reminders, nudges, CRM |
| Hours | Always on | Always on |
When WhatsApp alone is enough
- Customers find you on Google Maps, Instagram, Facebook or by referral and message directly.
- Your website is a one-page card with a WhatsApp button.
- Your business is local walk-in trade where the website barely matters.
Add a WhatsApp button to the site as described in the website button guide and let the agent do the rest.
When the website assistant matters most
- Customers research before contacting: schools, clinics, agencies, B2B, anything with a considered purchase.
- You run ads to landing pages and want questions answered on the page.
- International or desktop-heavy visitors who do not have WhatsApp open.
- You want a booking made without the visitor leaving the site.
The instructions differ from WhatsApp's; see website assistant instructions.
How they work together
The website assistant answers the first questions and offers two exits: book here, or continue on WhatsApp with a pre-filled message that names the page. The WhatsApp agent picks up with its own knowledge and the CRM. In ReplyKit the two have separate knowledge bases and instructions, share the inbox, and count replies against the same monthly allowance. One website assistant is included on Starter; Growth and Pro include more, alongside more WhatsApp numbers. Plans are in what it costs.
Deciding
Look at where your last thirty enquiries started. If most were website visits followed by a WhatsApp message, both. If most were direct messages from Maps, social or referrals, WhatsApp first, and add the website assistant when you see visitors leaving the pricing page without asking.
