A website chat widget under 30KB
A website chat widget gives visitors a way to start a support conversation while they browse your store. momo adds the widget with one script tag and states that its size is under 30KB; ask your developer for the exact embed snippet and confirm what the size includes before installation.
Why size matters
Why a smaller website chat widget matters for page speed
A website chat widget adds a support entry point to a storefront, but the bytes it uses and its effect on page speed are separate questions. A stated widget size under 30KB does not, by itself, tell you whether that figure means compressed transfer size, uncompressed JavaScript, or all assets loaded by the widget. It also does not establish how much a particular store's pages will change.
Smaller assets can limit the extra weight added to a page. That is a reason to ask how the figure was measured, not a page-speed result. No measured, dated performance score is available to report here. Avoid promising shoppers that installing a chat widget will make pages faster or leave speed unchanged.
Widget appearance and behavior settings should be treated the same way: describe only controls confirmed for the specific product and setup. If a setting matters to your storefront, such as where the widget appears or how it looks, ask the product team or developer to confirm it before making it part of your requirements.
From installation to a tested support flow
Treat installation, knowledge and handoff as one setup task. The goal is not just to see a chat icon; it is to know what visitors receive and what your team gets when the AI is unsure.
Install
Request the exact script tag
The widget is added to your website with one script tag. Ask your developer for the exact snippet and the appropriate placement for your site; do not copy a made-up example or assume another provider's instructions apply. For example, have your developer confirm the tag is placed on the intended storefront pages, then open those pages to check that the widget appears.
The widget code is added to the intended storefront pages.
Prepare
Add approved business knowledge
Provide the content the AI should use: a website crawl, PDFs, Word files, plain text or Q&A pairs. For example, a store can make its own product and delivery information available as knowledge so the AI can retrieve relevant passages when a visitor asks a question.
The AI has business content to retrieve and use when drafting answers.
Exercise
Try routine and uncertain questions
Use a routine question and a question the approved content does not answer. The AI retrieves knowledge, drafts an answer and checks that draft against its sources. When it is confident, it sends an answer with citations; below its confidence line, it says it is not sure and opens a ticket.
The team has checked how routine and unanswered questions are handled, including the route to a human.
What the support flow does
A widget is the visitor-facing entry point. The answers and the human route depend on the connected business knowledge and the shared inbox behind it.
Answers from your content
The AI retrieves passages from your business knowledge, drafts a response and checks it against those sources before answering with citations when confident.
Uncertain cases reach people
When confidence is below the set line, the visitor is told the AI is not sure and a ticket is opened for the team.
Inbox included on every plan
The shared helpdesk inbox is included on every plan, including Free, so teammates can take over conversations that need a human answer.
Shopify connection available
Shopify is available as an integration with an order-status action. Storefront widget installation and a Shopify connection are separate setup questions.
Website chat widget questions
Answers to common questions about installation, AI handoff and checking a storefront setup.
What does a website chat widget do?
It gives visitors a place on your website to start a support conversation while they browse. With momo, the widget connects visitors to AI answers grounded in your business knowledge, with a shared inbox for conversations that need a person.
How does an AI chat widget hand an uncertain question to a support team?
The AI retrieves relevant passages from your knowledge, drafts an answer and checks the draft against those sources. When confidence is below the set line, it tells the visitor it is not sure and opens a ticket for the team to review.
Does a website chat widget slow down a website?
A widget's asset size and its effect on page speed are different measures. The stated size for this widget is under 30KB, but that alone is not a measured speed result for your storefront; ask what the size includes and compare the same page under consistent test conditions.
How do I install a chat widget on Shopify?
Add the widget using its one script tag, but get the exact snippet and placement instructions from your developer or product team rather than using an example snippet. The Shopify integration is a separate connection; see the Shopify integration guide for its order-status action. If you use another site platform, ask your developer where the script tag belongs.
What should I check after adding a website chat widget?
Open the published storefront on desktop and mobile and make sure the widget appears on the pages where you intended to add it. Test a question answered by your approved knowledge and one the knowledge does not cover, then confirm the uncertain case reaches the shared inbox with the details your business chose to collect.
Set up the widget and test the handoff
Start free, add approved business knowledge, and test a visitor conversation through to the human inbox before relying on the widget for customer support.
