Using Sonomos with AI Platforms

Sonomos is designed specifically for the workflow of pasting or typing sensitive information into AI platforms. Here’s how to use it effectively.

Before you start

1. Install Sonomos and verify the risk widget appears
2. Enable Cloak for platforms you use regularly
3. Review the Quickstart to understand the traffic-light system

Platform-specific guidance

Claude.ai

Sonomos provides full automatic masking on Claude.ai. With Cloak enabled, PII in your messages is redacted before reaching Anthropic’s servers. The AI receives masked text, and your local view is restored with the original values.

Google Gemini

Full automatic masking support. Sonomos intercepts and masks PII within your messages before they’re transmitted to Google.

Grok (X/Twitter)

Full automatic masking support. Works the same as Claude.ai — outgoing messages are scanned and masked transparently.

ChatGPT and others

These platforms are covered by Send Guard. You’ll receive a warning banner or blocking modal when PII is detected, but automatic masking is not yet available for these platforms.

Tip

If you primarily use ChatGPT, consider manually reviewing and redacting PII before submitting. Send Guard will catch what you miss, but manual review plus Sonomos is the most secure workflow for platforms without automatic masking.

Best practices

• Always enable Cloak on supported platforms — it’s the most seamless protection
• Don’t disable Send Guard — it’s your last line of defense on uncovered sites
• Check the risk widget before submitting — a red indicator means high-severity PII is present
• Use compliance reports to document your PII handling for audits
