Shuttlewright Mask
Use any AI without exposing your real data by masking sensitive information locally in your browser

About Shuttlewright Mask
Shuttlewright Mask is a privacy tool designed for professionals who want to use AI models without risking their sensitive data. It automatically detects and replaces names, emails, phone numbers, financial details, and addresses with tokens before any information leaves your browser, ensuring the AI only ever processes the masked version.
Key Features
- Browser-based privacy: All masking and mapping happens locally in your browser; no data is uploaded or stored on external servers.
- Comprehensive detection: Identifies people, organizations, emails, phone numbers, payment cards, government IDs, addresses, and currency amounts.
- Customizable: Users can add their own terms, such as project codenames or specific client names, to the detection list.
- Two-way processing: Easily restore the original values once the AI provides its reply by pasting the response back into the tool.
- Flexible workflows: Supports manual copy-pasting into any AI model or using the built-in "Ask the AI" relay with an integrated pre-send leak check.
Pricing & Plans
- Desk ($0/mo): Free forever plan including browser-based masking, 1,000-character limit per text, and JSON export.
- Pro ($9/mo): Unlimited text length, custom term lists saved locally, "Ask the AI" relay access, and priority updates.
- Team ($29/mo): Includes 5 seats, shared custom dictionaries, a deploy-in-your-own-stack option, and email support.
Frequently asked questions about Shuttlewright Mask
Where does my data go when I use Shuttlewright Mask?+
Your data stays in your browser. Masking runs locally in your browser tab, and there is no account, database, or server upload involved.
What information is actually sent to the AI model?+
Only the masked text is sent to the AI model. You can either copy and paste the masked version yourself or use the 'Ask the AI' relay, which performs a final leak check before sending.
Does this tool make my data fully anonymized or GDPR-safe?+
No. Masking is a form of pseudonymization that reduces risk, but it does not guarantee full anonymization or legal compliance, as the remaining context in your text may still be identifiable.
Can I use my own custom terms for masking?+
Yes, the Pro and Team plans allow you to add your own custom terms, such as specific project codenames or client names, to the detection list.
