Blank.tools Sanitizer

A free, browser-based utility designed to automatically remove or replace personal and sensitive data before sharing text with AI systems, APIs, or other people. The tool runs entirely on the client side — no data ever leaves your browser — making it a safe and private option for anyone who wants to keep control over their information.

With Blank.tools Sanitizer, you can paste in raw text that contains personal identifiers (such as names, addresses, phone numbers, or account details) and instantly transform it into a sanitized version. Detected sensitive elements are replaced with structured placeholders, ensuring that your text remains useful for testing, collaboration, or AI input while protecting the underlying personal information.

The sanitizer is designed for developers, researchers, students, and privacy-conscious users who frequently handle real-world data but need a quick and reliable way to anonymize it. Whether you are preparing test cases, redacting documents, or cleaning inputs for AI prompts, blank.tools/sanitizer provides a simple workflow that minimizes risk without sacrificing usability.

Key benefits include:

• Privacy-first design: all processing happens locally in your browser.
• No server storage: your input text is never uploaded or saved.
• Clear placeholders: replaced values remain structured and readable.
• Free and open use: accessible to anyone, without registration.
• Blank.tools Sanitizer gives you control and confidence when working with sensitive information.
