# Install the Chrome and Edge extension
> Access your Cassidy Agents from any webpage with the browser extension for Chrome and Edge.
The Cassidy browser extension lets you chat with your [Agents](/agents/overview) while browsing any website. Summarize articles, draft email replies, write LinkedIn messages, and analyze page content — all without leaving your browser tab.
The extension works with both **Google Chrome** and **Microsoft Edge**.
## Install the extension
Go to the [Cassidy AI extension](https://chrome.google.com/webstore/detail/cassidyai/kmkfkldjbchieogojgcbalncifahjogg) in the Chrome Web Store. You can also access this store from Microsoft Edge.
Click **Add to Chrome** (in Chrome) or **Get** (in Edge) to start the installation.
A dialog will ask for permission to add the extension. Review the request and click **Add extension** to allow Cassidy to read page content.
For quick access, pin Cassidy to your browser toolbar. Click the **puzzle piece** icon in the toolbar to open the extensions menu, then click the **pin** icon next to Cassidy.
Once pinned, you'll see the Cassidy icon in your toolbar. Click it to open the extension and start chatting with your Agents.
## Configure the extension
After installing, you can customize when and how the extension appears.
Locate the Cassidy tag in the bottom-right corner of your browser window. Hover over it to reveal the **gear** icon, then click it to open settings.
In the settings menu, configure when to show the Cassidy tag:
* **Show Cassidy icon on all browser tabs** — displays the tag on every webpage you visit.
* **Show Cassidy icon when selecting text** — displays the tag only when you highlight text on a page.
Your preferences save automatically when you close the settings menu.
When the Agent needs to read your current page, it requests your permission. You can respond in one of three ways:
* **Always allow** — the Agent reads the page automatically on every message without prompting again.
* **Allow once** — the Agent reads the page for this message only and asks again next time.
* **Deny** — the Agent responds without reading the page.
You can change this preference at any time from the **Tools** dropdown in the chat input area. Toggle **View Page** on or off to control whether the Agent automatically reads pages.
## What you can do with the extension
### Draft email replies
When viewing an email in Gmail, click the **Automate** button that appears next to the reply buttons. The Cassidy chat panel opens with a suggested prompt based on the email thread, giving you a starting point for your reply.
### Write LinkedIn messages
On LinkedIn, the **Automate** button appears next to message controls. Click it to open the chat panel with a pre-filled prompt that helps you craft a personalized message based on the conversation context.
### Summarize and analyze webpages
Click the Cassidy tag on any webpage to open the chat panel. Ask your Agent to summarize the page, extract key takeaways, or answer questions about the content. The Agent automatically reads the page to provide context-aware responses.
### Work with selected text
Highlight any text on a page to trigger the Cassidy tag (if the display setting is enabled). Click it to open the chat panel with the selected text included, so you can ask your Agent to rewrite it, translate it, explain it, or use it as context for a task.
