Page speed affects where Google ranks a page and how many visitors stay on it. So instead of telling you Zinn® Chat is light, we installed it on a clean WordPress test site and measured what it adds to a page.
On the same test page, tawk.to added +234.9 kB and 14 requests to other companies' servers. Zinn® Chat added +1.6 kB and 0.
Measured on 2026-10-01: Zinn Chat 2.9.2 on a clean WordPress test site, using Lighthouse's test for phones, run 5 times and taking the middle result. Page weight counts everything a visitor's browser downloads within 15 seconds, including after a scroll. Every result, and how we measured it · Compare with other plugins
The assistant reads your posts, pages, products and custom fields, answers only from them with a link to the page it used, and says it does not know rather than guessing.
Chats and tickets are stored in your WordPress database and work with its own Export and Erase Personal Data tools. The AI uses your key, billed by your provider.
The launcher is about 2 KB, drawn after the page has loaded and fixed in the corner so it cannot shift the layout. The chat itself loads only when somebody opens it.
Guides, the full documentation and the latest news are on zinnchat.com.
Zinn® Chat puts a complete help desk inside WordPress. An AI assistant answers visitors from your own pages and links the page it used. When it cannot answer, it says so and hands the visitor to a person or takes their question as a support ticket. Your team answers live chats from a multi-chat inbox in wp-admin, and customers follow their requests on a support page or in their WooCommerce account. Everything runs on your site and stays in your database, and the AI uses your own key with the provider you choose.
Most chat services charge per person answering and keep your conversations on their servers. Zinn® Chat is a WordPress plugin: the free version has no seat limit, the chats and tickets live in your own database, and the AI is billed by the provider whose key you paste in, at their price. The launcher is about 2 KB and the chat loads only when somebody opens it, so pages nobody chats on stay as fast as they were.
Zinn® Chat makes your WordPress site an MCP server: Claude, Cursor, VS Code and other AI assistants can use its 36 actions with your permissions.

✓ yes · • partly, or only on a paid plan or add-on · ✕ no · — not confirmed on their own pages Competitor facts last checked on 2026-10-01. Something out of date? Tell us and we will correct it. The speed rows were measured on 2026-10-01 on a clean WordPress test site: the same page, each plugin's free version, Lighthouse's test for phones run 5 times, taking the middle result. In those rows, — means not measured, because the plugin is paid-only or needs an account we did not create.
Your team answers from a multi-chat inbox in wp-admin, with the page the visitor was on, saved replies, internal notes and one click to make a ticket.

Support tickets live in wp-admin too, with status, priority and who is handling each one.

The facts about the file, the requirements and how to install 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.
4bd292674ce6b08a314c17dee31d812a821d3b065fe85be6f55e3042cfb42b62sha256sum zinn-chat-2.12.14.zipshasum -a 256 zinn-chat-2.12.14.zipcertutil -hashfile zinn-chat-2.12.14.zip SHA256The 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.
WordPress 6.9 or later and PHP 7.4 or later. An API key from an AI provider (Google Gemini, OpenAI, Anthropic Claude, Mistral, OpenRouter, DeepSeek or any OpenAI-compatible service) for the assistant; live chat and tickets work without one.
Zinn® Chat is installed for you on every WordPress site Zinn Digital® hosts. On any other host, install the free plugin, paste an AI key and switch the chat on. Zinn® Chat Pro adds a whole team, a knowledge base and email replies on top.
Use the download button above. Keep the file as it is — do not unzip it, because WordPress expects the archive itself.
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.
Choose Upload Plugin, select the zip you just downloaded, then Install Now. WordPress unpacks it for you.
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.

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.
Only for the assistant. Live chat, tickets and the support page work without one. With a key, you pay your AI provider directly at their price; Zinn® Chat adds no charge per answer.
Google Gemini, OpenAI, Anthropic Claude, Mistral, OpenRouter, DeepSeek and any OpenAI-compatible service. The newest model is chosen from the provider's own list, and you can pick another.
The launcher is about 2 KB and is drawn after the page has loaded. The chat window is fetched only when a visitor opens it.
Yes. The assistant reads products, prices, stock, shipping and payment methods, signed-in customers can ask about their own orders, and accounts get a Support tab.
In your own WordPress database. WordPress's Export and Erase Personal Data tools include everything Zinn® Chat stores, and old chats can be deleted automatically.
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.
Customers can download the newest release of each of the two previous major versions of every plugin in the Zinn Digital® app. It is there for a site that cannot run the current version yet — one still on an older WordPress or PHP — and for rolling back an update that caused a problem. When you can, install the current version.
Zinn® Chat comes installed and activated on every WordPress site we host on our own servers, and we keep it up to date for you. It also runs on any other WordPress site.
