# Locke vs Generic Browser Content Blockers

Ad, tracker and site blockers work at the network layer: they stop connections or scripts from loading. They can't read the text inside a chat box, tell a privileged document from a harmless one, or mask sensitive data while letting the rest of a prompt through.

## When Generic browser content blockers fits

- You need to block whole categories of sites or trackers across the entire browser.
- Your goal is to prevent a tool from being used at all rather than to govern what is sent.

## When Locke fits

- AI tools are part of daily work and a blanket block is not realistic.
- You need fine-grained control: allow general use, intercept specific data categories.
- You want users to see why something was flagged and to choose mask, redact, or override per case.

## Side-by-side

| Dimension | Locke | Browser blockers |
| --- | --- | --- |
| Granularity | Field-level: detects categories within free-form text. | Page- or request-level. |
| Action | Mask, redact or block, chosen per match. | Block or allow. |
| Visibility | Traffic-light widget shows current risk state. | Usually invisible until something breaks. |
| Use case | Govern AI prompts without breaking AI workflows. | Block ads, trackers, or whole domains. |

## Bottom line

Content blockers and Locke solve different problems. To block connections outright, use a blocker. To let people keep using AI while specific data stays off the wire, use Locke.
