For folks looking for a solution to protect sensitive information from leaking into OpenAI, this is the right tool to install. It's easy to use and work seamlessly on every prompt i submit. When i send sentences with a credit card number or SSN in it, it shows up an interactive window to either redact the text before sending it or send the original one after making sure it's okay. A powerful plugin to have if you use ChatGPT in your daily work!

It is important to our team to makes sure sensitive data doesn't end up where it shouldn't. This solution redacts sensitive information from ChatGPT prompts, allowing us to rest a little easier knowing our sensitive data is safe! Setting it up was quick and easy- this is a must have if your team is using ChatGPT.
