How to choose
Match the tool to the exact data surface: on-device for personal email or meetings, self-hosted proxies for API calls, and browser verification for content authenticity. Watch for tools that claim privacy but still require accounts or send metadata. Avoid generic scanners when you need specific standards like C2PA or GDPR flagging. Test offline functionality first since many options only work when fully disconnected.
