Zinn® Chat
Live chat on your own website — answered by AI when you are busy, handed to a person when it matters, and emailed to you when you miss it.
What Zinn® Chat does
A chat box in the corner of your site that your visitors can open and type into. When somebody asks something your website already answers, the assistant answers it — from your own pages, not from a script somebody wrote once and forgot. When it cannot, or when the visitor asks for a person, it hands the conversation to you and says so. You answer every site you run from one inbox, with saved replies for the things you type twenty times a week and a transfer button for the things a colleague should take. If nobody is there, the visitor leaves their email address and the whole conversation arrives in your inbox rather than being lost.
Why it matters
Chat widgets are the heaviest thing most small sites load, and they are loaded on every page whether or not anybody opens them. The usual ones cost several hundred kilobytes and several requests before a visitor has clicked anything. This one is under five kilobytes and makes no request at all until the visitor opens it — the settings it needs are already on the page. It cannot move your layout while it loads, because it is positioned out of the document flow and lives in its own shadow root where your theme's CSS and its own cannot reach each other. And it does nothing whatsoever until you switch it on: no script, no cookie, no request.
What is in it
Under 5 KB, and nothing before a click
The whole widget is 6 KB compressed, with no framework behind it, and its configuration is written into the page rather than fetched. A visitor who never opens the chat pays for one small script and nothing else — no round trip, no third-party connection, no layout shift.
It answers from your own website
The assistant reads the pages you already publish, so it answers about your opening hours, your delivery countries and your prices rather than inventing them. When it does not know, it says it does not know and offers the visitor a person — which is the answer that keeps a customer.
One inbox for every site you run
Conversations from all your sites arrive in one place, with the page the visitor was reading, their language and their browser beside each one. Saved replies are shared or per-site, and a conversation can be transferred to a colleague without the visitor being asked to explain it again.
Nothing is lost when nobody is there
Outside your business hours the widget asks for an email address and tells the visitor when you will reply. The conversation is emailed to you in full, so you answer a person rather than a notification saying somebody tried to reach you.
It is off until you turn it on
The plugin ships with our hosting and stays completely inert until you save a key and tick the box — no script on the page, no cookie set, no request made. That is a consent decision, not a default, and it is yours to make.

What Zinn® Chat needs
WordPress 6.6 or later and PHP 8.2 or later. A Zinn Digital® account, and the widget key from your Zinn® dashboard. No other plugin, no jQuery and no theme support are required. On a site that is not WordPress, one line of script does the same job.
How you get Zinn® Chat
Install and activate it, open Settings → Zinn® Chat, paste the widget key from your Zinn® dashboard, add the domains the widget is allowed to run on, and tick Enable. Answer from Live chat in the dashboard. To put it on a site that is not WordPress, copy the script line from the same screen into that site's HTML.
Built to WordPress.org plugin-directory standards: the WordPress Coding Standards, a security review, no PHP notices, and translation-ready in every language we sell in.
Installing it
WordPress installs a plugin from a zip file without you unpacking anything. The whole thing takes about a minute, and you need an administrator account on the site.
Download the zip
Use the download button above. Keep the file as it is — do not unzip it, because WordPress expects the archive itself.
Open Plugins → Add New Plugin in wp-admin
Sign in to your site's wp-admin, open Plugins in the left-hand menu, then Add New Plugin at the top of the page.
Upload and install
Choose Upload Plugin, select the zip you just downloaded, then Install Now. WordPress unpacks it for you.
Activate it
Choose Activate Plugin when the upload finishes. The plugin's own settings then appear in wp-admin — nothing else is required to start using it.
Checking the file is ours
This is code that will run on your site, so you should be able to prove the file you downloaded is the file we published. Run the command for your computer against the zip and compare the result with the checksum below — they must match exactly, character for character.
- SHA-256
04eb6922d3d1c449ca23a5b78b8aa6479e397ce73456628e2da20b3e50e73f3f- On Linux

shasum -a 256 zinn-chat-1.0.0.zip- On Windows
certutil -hashfile zinn-chat-1.0.0.zip SHA256
The download itself also returns the same value in an X-Zinn-Package-SHA256 header, so an automated deployment can check it without reading this page.
Changelog
1.0.0 — first release: the widget in its own shadow root at under 5 KB; AI replies grounded in the site's own content, with a hand-off to a person; one operator inbox across every site; saved replies, transfer and business hours; offline conversations emailed with the full transcript.
Updates
On a site we host, these plugins are configured to update themselves: they check with us and WordPress installs the new version for you, with the download verified against its published checksum first. On a WordPress we do not host, there is nothing to configure and nothing phones home — come back to this page when you want the newest version, or watch the plugin's GitHub releases.
Get Zinn® Chat working on a real site
Every plugin here is free and runs on any WordPress. On a site we host they are installed and kept current for you, so there is nothing to download and nothing to update.
