Aporta

Detects sensitive data in your prompt and replaces it with reversible tokens before it leaves the browser, on supported AI tools.

Aporta helps organizations use public AI tools without handing them sensitive values. Aporta protects five AI tools, in Chrome and Edge. Aporta finds sensitive data in what you type into ChatGPT, Claude, Gemini, Microsoft Copilot and Perplexity, and replaces it with reversible tokens before your text leaves the browser. When the tool answers, Aporta restores your own values so the reply is readable. What it covers What you type into the message box on each of the five tools, in Chrome and Edge, including Microsoft 365 Copilot chat in the browser. One exception: Edge does not allow any extension to run at Copilot's older web address, so in Edge, blocking that address is the control that works. Where your administrator has turned on attachment scanning, Aporta also covers spreadsheets, Word documents and presentations you attach. PDFs and scanned images are not scanned. The exact web addresses are the permissions this extension requests, which your browser shows you before you install. What it does not cover Aporta does not protect AI tools generally. On any other AI site, your organization's policy decides whether you are blocked or redirected to a supported tool. AI built into another application, such as Copilot inside Word, Excel, PowerPoint and Outlook, or Einstein inside Salesforce, is outside what a browser extension can reach. Aporta protects identifiers it recognizes; it does not protect confidential subject matter that contains no recognizable identifier. What happens to your text Some detection runs on your own device and never leaves it. More complex detection runs on Aporta's servers, which means the text in the message box is transmitted to Aporta when you pause typing, not only when you press send. Text you type and then delete has therefore already been sent for detection. It is processed in memory and not retained. Aporta does not record the AI tool's responses. Aporta does not sell personal data, does not share it for advertising, and does not train models on your content. Aporta is sold to organizations. It is configured by an administrator and reports to them what left the organization's control. Full detail: aportasystems.com/legal/privacy and aportasystems.com/legal/supported-tools.
