What it detects
The extension monitors sessions to known AI web app domains. A “session” is counted when a user starts a conversation with an AI tool, not just when they visit the page.Monitored (full session content)
For these web apps, the extension captures full session content, including prompts, completions, and tool calls:- Claude.ai
- ChatGPT
- Gemini
Discovered (domain-level detection)
For these web apps, the extension detects that the agent is being used, but does not capture session content:- Deepseek
- Grok
- Perplexity
- Mistral
- Cohere
What appears in the inventory
Discovered browser agents appear in the same agent inventory as endpoint and CLI agents:| 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 |
Supported browsers
- Chrome
- Edge
- Firefox
Deployment
The browser extension is deployed via managed browser policies, such as Chrome Enterprise policy push. The extension is configured with your Oso Environment ID at install time. This approach allows organization-wide deployment without requiring individual employees to install anything manually.Privacy considerations
The browser extension’s detection behavior depends on the agent:- Monitored agents: full session content (prompts and completions) is captured and sent to Oso
- Discovered agents: only domain-level visit data is captured. Oso knows which AI tool was accessed, not what was discussed
