# Browser Extension

> Monitor browser-based AI tool usage alongside your coding agents.

The Oso browser extension monitors browser-based AI tools such as ChatGPT, Claude.ai, and Gemini. The extension is currently only available through [Managed Deployment](/oso-for-agents/integrations/managed-deployment).

## What it monitors

The extension watches sessions to known AI web app domains. A "session" is counted when a user starts a conversation, not just when they visit the page.

### Full session monitoring

For these tools, the extension captures prompts, completions, and tool calls:

* Claude.ai
* ChatGPT
* Gemini

### Usage detection

For the following web apps, the extension detects that the tool is being used but does not capture session content:

* Grok
* Deepseek
* Perplexity
* Mistral
* Cohere
* Microsoft Copilot

## What appears in the dashboard

Browser sessions appear in the same [agent inventory](/oso-for-agents/shadow-ai) as coding agent sessions:

| Column        | Description                                              |
| ------------- | -------------------------------------------------------- |
| **Agent**     | The AI web app detected, tagged as "Browser" environment |
| **Users**     | Which users accessed the web app                         |
| **Devices**   | Which devices the access came from                       |
| **Last Seen** | When the agent was last used                             |

The detection source shows "Browser Extension" so you can distinguish it from EDR or proxy-based sessions.

## Supported browsers

* Chrome
* Edge (Chromium-based)

## Privacy

The extension's capture behavior depends on the tool:

* **Full session monitoring**: prompts and completions are captured and sent to Oso.
* **Usage detection only**: Oso records that the tool was accessed, not what was discussed.

For details on how Oso handles this data, see [Data Privacy](/oso-for-agents/data-privacy).
