Start with pre-built UIs or build your own
Your chat, your way. Get started in minutes with fully customizable pre-built UIs, or build your own combined with real-time chat data with the JavaScript Data API.
The TalkJS Chatbox is just the right half of the Inbox UI mode. It takes up less space and is designed to be embedded in your app near an order confirmation, a booking, or user profile.
The TalkJS Inbox shows the chat history on the left, selected conversation on the right. It's designed to act as the messaging center of your app, usually living on its own page.
You can also show a conversation in a popup that only shows up when the user clicks a button somewhere. When shown, the popup is positioned on the bottom right of your page.
Customize everything and anything
TalkJS provides prebuilt themes you can use right away or customize to match your brand’s design and user experience.
Themes give you complete control over how your chat looks and feels—from overall layout and message styling to fonts, colors, and interactive elements. You can fine-tune every visual detail, extend functionality, or design a fully bespoke chat interface.
Whether you start from a default theme or build your own, TalkJS provides a flexible foundation to create a consistent and responsive chat experience within your product.
We chose TalkJS because it offers built-in email notifications and a plug-and-play chat UI that was easy to implement from day one.
