# Capabilities
> What end users get when a Wolters Kluwer product embeds the Libra SDK
The SDK puts the Libra legal-research chat inside a Wolters Kluwer product, beside the content the user is already working with. This page is the overview; the pages under it describe each area in detail, and the [integration guides](/guides/embedding) describe how a product wires it up.
Wolters Kluwer product material calls this the **Libra Add-in**. These docs say *embedded widget*, to keep it distinct from the Word and Outlook add-ins — a separate surface whose conversations live in their own list and do not appear here.
## What the widget is
It is the Libra chat, running in an isolated iframe inside your product, signed in as the user's own Libra account. Conversations, projects, uploaded files and assistants are the **same records** the user sees in the Libra Workspace — not a copy. A chat started in the widget can be finished in the Workspace and vice versa.
Composer, answer modes, voice input, answer actions, and how citations are presented.
Research sources, the document on screen, uploads, @-mentions, projects and history.
What each subscription includes, the usage limits, and what only the Workspace can do.
Every `productId` and `ResearchSourceId` the SDK accepts.
## What it does, in one screen
Research grounded in the product's Wolters Kluwer sources, answers that cite what they used, and the document the user is reading available as context in one click.
## What is in the widget, and what is not
| In the embedded widget | Libra Workspace only |
| ---------------------------------------------------- | -------------------------------------------- |
| Chat, with research over the product's sources | Creating or editing assistants and workflows |
| **Running** an existing assistant or workflow | Review, Discovery, Playbooks |
| Uploading and attaching documents | Drafting documents |
| Chat history and project switching (current project) | Creating projects |
| Citations, export, email drafting | Team and subscription administration |
Users reach the Workspace through **Continue in Libra**, which opens the same conversation in a new browser tab. See [Chat handoff](/guides/chat-handoff).
## Fourteen languages
`en-US`, `de-DE`, `de-CH`, `pl-PL`, `nl-NL`, `nl-BE`, `fr-BE`, `fr-CH`, `it-IT`, `it-CH`, `ro-RO`, `hu-HU`, `cs-CZ`, `sk-SK` — switchable at runtime without losing the conversation, and the sign-in screen follows the same language. See [Locales](/guides/locales).
## Sign-in without leaving the product
Existing users sign in through a popup; new users can create an account and complete onboarding inside the widget. Products with their own single sign-on can remove the popup entirely with [proxy mode](/guides/proxy-mode). Accounts in a restricted state see a clear notice rather than a blank panel. See [Authentication](/guides/authentication).
## Version and release cadence
Every release is listed in the [changelog](/changelog), published to WK Artifactory and the WK CDN together, so products upgrade deliberately.
