Tacitum for the browser

Description

Anonymises on your computer the files you add to ChatGPT, Claude, Gemini, Le Chat or Copilot before upload. Needs the Tacitum app. Tacitum for the browser anonymises your documents on your computer before they are sent to a web AI assistant. When you drop, paste or pick a file in ChatGPT, Claude, Gemini, Le Chat or Copilot, the extension asks whether to anonymise it. The Tacitum app, installed on your computer, analyses the document offline and shows you the data it masks. Once you approve, the anonymised version is added to the conversation instead of the original: names, addresses, phone numbers, emails and identifiers are replaced with labels such as [NAME-A2H7KQ]. • Nothing leaves before you answer: "Anonymise", "Send without anonymising" or "Cancel". • Already anonymised on your computer? The extension offers to reuse the version you already checked. • A safeguard blocks the upload of any file that did not go through Tacitum. • Long pasted text (emails, notes) can also be anonymised before it is inserted. • "Show in clear" under an answer: it is displayed in place with your real values, in an extension frame the site cannot read. Paste one of these values back into an assistant: the extension warns you. • Under a file produced by Claude, ChatGPT, Gemini or Copilot: "Download (restored values)" saves a copy with your real values through the browser, "Open" creates it on your computer and opens it in Word (tracked changes and comments kept). • The extension button shows Tacitum's status and lets you turn a site off, pause protection (15 min, 1 hour, until tomorrow) or anonymise without being asked on each upload (the review stays mandatory). • Everything stays local: the extension only talks to the Tacitum app on your computer and sends nothing to the publisher. IMPORTANT: the extension requires the Tacitum app for Windows, available from https://tacitum.tools/en/ (free trial of 10 conversions, extension included). Without it, the extension tells you so and offers the download link. It is then included in Tacitum's AI Connector. Beta version. Text typed on the keyboard, or pasted text shorter than 400 characters, is not intercepted. Tacitum is not affiliated with OpenAI, Anthropic, Google, Mistral AI or Microsoft.
