Getting Started

The fastest path to rollout is install, pin, verify, then invite the rest of the team once the workflow is approved. This guide walks through each step in detail.

Install the extension

Start from the Chrome Web Store listing and click "Add to Chrome." The extension will install automatically and appear in your browser's extension menu.

After installation, pin Blur to the browser toolbar so the protection state and review panel are always visible to end users. To pin:

1. Click the puzzle piece icon in the Chrome toolbar (Extensions menu)
2. Find "Blur" in the list
3. Click the pin icon next to it

Once pinned, the Blur icon will remain visible in the toolbar at all times, giving users quick access to detection status and settings.

Create an account and sign in

Blur requires an account: detection does not run until the user signs in. The free plan needs no subscription or credit card.

1. Open one of the supported AI surfaces (ChatGPT, Claude, or Gemini)
2. The Blur widget will prompt you to sign in to activate protection
3. Create a free account or sign in with existing credentials

The signed-in state persists across browser restarts, so this is a one-time step per browser profile.

Verify detection

Before rolling out to your team, verify that detection is working correctly on each supported platform:

1. Open one of the supported AI surfaces (ChatGPT, Claude, or Gemini) and confirm you are signed in
2. Type a sample prompt that contains recognizable sensitive data, for example: "Draft an email to John Smith at john.smith@acme.com about the project"
3. Confirm that Blur detects and highlights the name and email address
4. Verify that the masked version replaces the sensitive content with clean placeholders

Troubleshooting: If the Blur widget is not visible on a supported site, check the following:

• Confirm the current URL matches one of the supported domains (chatgpt.com, claude.ai, or gemini.google.com)
• Confirm you are signed in — detection stays off for signed-out users
• Make sure the extension is enabled in chrome://extensions
• Try refreshing the page after enabling the extension
• Check that no other extensions are conflicting with content script injection

Configure detection categories

Blur organizes detection into four categories, each with granular per-type toggles you can switch on or off individually:

• Contact & Addresses: email addresses and phone numbers (free), plus locations & addresses and links & URLs (Individual & Enterprise)
• Names & Entities: people's names (free), plus companies & job titles and schools & institutions (Individual & Enterprise)
• Financial & IDs (Individual & Enterprise): SSNs, credit card numbers, bank details, and other regulated identifiers
• Sensitive Attributes (Individual & Enterprise): health & medical, age/gender/identity, religion, relationships, and sensitive dates

The free tier masks people's names, email addresses, and phone numbers. Everything else unlocks on Individual or Enterprise. Open the Blur popup from the toolbar to review and adjust which detection types are active — your choices, mask style, and theme sync automatically across every supported site in the same browser profile.

Roll out to a team

Organization owners can invite teammates and manage billing in the Blur dashboard. The recommended rollout process:

1. Pilot phase. Start with a small group (3 to 5 users) who regularly use AI tools in their workflow
2. Validate categories. Have pilot users test detection against real prompt patterns to confirm the right categories are enabled
3. Approve the workflow. Get sign-off from security or compliance stakeholders on the detection and masking behavior
4. Expand invites. Once approved, invite the rest of the team through the dashboard so access, seats, and billing stay centralized

Use the dashboard to track seat usage, manage roles, and handle billing in one place.
