Overview

Stops personal data and secrets reaching AI chatbots. Checks on your device; your messages never leave the browser.

Tidewall checks messages typed into AI chat tools (such as ChatGPT, Claude, Gemini and Copilot) for personal data and secrets at the moment the user presses Send, and lets the user redact, edit or block the message before it is sent. All checks run locally in the browser; message text is never stored or transmitted.
