AI Eraser is a privacy assistance tool for ChatGPT users, whose main purpose is to help redact potentially sensitive personal information contained in prompts before users submit them, thereby reducing the risk of this information being sent to large language models (LLMs). According to its official description, the tool is provided as a Chrome extension and is completely free.
Purpose The core purpose of AI Eraser is to "redact personal data from ChatGPT prompts," with official examples including Social Security numbers (SSN), API keys, email addresses, and more. It aims to protect user data from being obtained by LLMs by replacing sensitive text before sending.
Main capabilities After installing the extension, when users visit ChatGPT.com, a green "Redact" button appears in the message bar. Clicking this button performs the redaction operation, and clicking it again undoes the redaction. The official description explicitly states that AI Eraser is "far from perfect," and users are responsible for reviewing the redacted prompt and ensuring it has been properly redacted, and will likely need to make manual edits. The extension runs entirely locally on the device and does not need to send data anywhere.
How to use The way to use it is to first install the Chrome extension, then visit chatgpt.com, find and click the "Redact" button in the message input area to redact, and click it again to undo. Users should verify the redaction results themselves and manually modify them if necessary.
Privacy and permissions According to the official statement, AI Eraser does not collect any data, runs entirely on the user's device, and does not transmit data. It requests the activeTab permission in order to access the current ChatGPT window and edit the prompt; this access is temporary and ends when the tab is closed. The extension is only active on the URL chatgpt.com. The official statement also explains that it will not sell, trade, or otherwise transfer information to outside parties, does not retain any information, and because it does not store personal data, there is no personal information for users to access, modify, or delete. Users can control its functionality by enabling or disabling the extension in the Chrome browser, and can also delete the extension at any time.
Applicable scenarios It is suitable for users who, when using ChatGPT, want to reduce the risk of accidentally submitting sensitive personal information (such as SSN, API keys, email addresses, etc.). It is especially suitable for scenarios where users are more concerned about privacy and need to handle sensitive content in prompts.
Limitations Officially, it is emphasized that AI Eraser's redaction is not perfect, and users must check and manually edit it themselves; complete redaction cannot be guaranteedof all sensitive information. In addition, the extension is only active for the chatgpt.com URL, and support for other platforms or websites is not yet provided. Regarding more details such as whether the tool supports other browsers, whether it has other features besides the "Redact" button, and how frequently it is updated, official information is not yet available.
