What is MaskmyPrompt?
MaskmyPrompt is a web-based utility that processes text prompts to remove sensitive information before submission to large language models. The tool's core function is to identify and substitute specific categories of confidential data, including the names of people, organizations, and locations. A user inputs their text into a designated field, and the software automatically replaces the identified entities with fictional placeholders. The output is a modified, anonymized version of the original prompt, which can then be copied for use in external AI chat interfaces. The software is intended for professionals who handle proprietary or confidential information, such as legal, healthcare, and corporate personnel. A primary use case involves a lawyer drafting a case summary for AI analysis without exposing client or company names. Similarly, a business strategist can use it to explore partnership scenarios with an LLM by substituting real company names with generic placeholders. A developer might also use it to get assistance with proprietary code by masking internal project identifiers before sharing snippets.
