A website chat widget that shares your WhatsApp AI Brain.
Paste one script tag on your site. Visitors get a chat bubble that answers from the same AI Brain, tone, and escalation rules as your WhatsApp, Instagram, and Messenger inbox, and every conversation lands in the same shared inbox your team already checks.
No separate line item. It ships with every Business workspace (Starter $59/mo, Growth $129/mo, Pro $349/mo), with no added per-message fee for website replies.
The short answer
What is the Instant Reply website chat widget?
It is a floating chat bubble you add to any website with one script tag. When a visitor sends a message, Instant Reply opens an anonymous session and runs the message through the exact same AI reply engine that answers your WhatsApp, Instagram, and Messenger DMs, meaning the same knowledge base, tone settings, and escalation rules, because that lookup is scoped to your workspace, not to one channel. The reply comes back in the widget, and the conversation is saved to your shared team inbox as a website conversation, next to your other channels.
Key facts
- Installs with one script tag: <script src="https://www.instantreply.co/chat.js" data-org="..." async>. No iframe, no page rebuild.
- Runs through the same reply pipeline as WhatsApp, Instagram, and Messenger, so it answers from the same AI Brain and the same escalation keywords.
- Every website conversation lands in your shared team inbox next to your other channels, not a separate chat-widget dashboard.
- Website replies carry no Meta per-message fee, unlike WhatsApp messages sent outside the free service window.
- An origin allowlist, a per-IP session limit, and a per-session message cap are on by default, so a stranger can't turn the widget into a free AI endpoint.
Best fit
Use it when your site gets the same questions your team already answers on WhatsApp or Instagram.
This page is for teams comparing website chat widgets, AI live chat plugins, and WhatsApp chat buttons for a website.
Best fit
Teams that already trained an AI Brain for WhatsApp or Instagram and want a visitor who lands on the website first to get the same accurate answers, without a second knowledge base.
What it does not do yet
It does not link a website visitor's identity to their WhatsApp number. A website conversation and a WhatsApp conversation from the same person are two separate threads in the shared inbox, not one merged history.
Do not use it for
A plain WhatsApp click-to-chat button. If all you want is a link that opens WhatsApp with a prefilled message, a free wa.me link does that without any setup.
How it works
How the widget connects to your existing AI Brain
Paste one script tag
Copy the snippet from Dashboard > Website Agent and add it before </body>. It renders in its own shadow DOM, so your site's CSS cannot break the widget and the widget cannot restyle your page.
A visitor opens the bubble
Opening the widget starts an anonymous session scoped to your organization. Nothing is saved until they actually send a message, so a visitor who never types anything does not show up as an empty conversation.
The same AI Brain answers
The message runs through the identical reply pipeline as your WhatsApp and Instagram inbox: your trained knowledge base, tone settings, and escalation keywords, looked up by workspace, not by channel.
It lands in your shared inbox
The conversation is saved as a website thread next to your Instagram, WhatsApp, and Messenger conversations, so a team member can take over from the same inbox they already use.
Why teams choose it
Why one AI Brain across every channel beats a separate chat-widget tool
Most website chat widgets are their own product with their own knowledge base. This one already knows what your WhatsApp AI knows.
No second knowledge base to maintain
Your FAQs, pricing, and policies are trained once and answer on WhatsApp, Instagram, Messenger, and your website. Update the Brain in one place instead of copying answers into a separate widget tool.
One inbox, not a new tab
Website conversations show up in the same team inbox as your other channels, so nobody has to log into a separate chat-widget dashboard to see what visitors are asking.
No Meta fee on website replies
WhatsApp messages sent outside the free service window carry a Meta conversation fee. Website chat has none, because there is no WhatsApp API in the path.
Abuse control on by default
An origin allowlist, a per-IP hourly session limit, and a per-session message cap are enforced before the AI is ever called. Visitor IPs are hashed, never stored raw.
Best fit
Perfect for teams that move fast in DMs.
A visitor who isn't ready to hand over a WhatsApp number
Scenario
Someone lands on your pricing page from a Google search, not your Instagram. They ask a product question in the widget and get the same accurate answer your WhatsApp AI would give, without leaving the site or becoming a contact first.
Outcome
After-hours questions on your own site
Scenario
A customer checks your website at 11pm with a shipping question. The AI answers from the same policies it uses on WhatsApp, and escalates to your shared inbox if it cannot help, ready for the morning.
Outcome
One less system to wire up
Scenario
You already trained an AI Brain for WhatsApp. Turning on the website widget does not mean training a second bot on a different FAQ file inside a different tool.
Outcome
Works on any site that takes a script tag
