There are two parts: the settings in the apps you use, and protecting the photo itself.
1. Check the AI settings in your apps
Instagram, Facebook and other apps change their AI and data settings often, and options differ by country. Open the app's Settings, search for "AI", "privacy" or "data", and read what is offered for your account. The app's own Help Center has the current steps - follow those rather than old guides.
2. Protect the photo before you post
Settings cannot stop a stranger from saving a public photo and editing it with AI. Photo Shield adds an invisible anti-AI layer so AI editors misread the photo.
How to use it (3 steps)
- Open Photo Shield and choose a JPG, PNG or WEBP photo. It stays on your device.
- Leave the bars on full protection (the default) and press Protect my photo. It takes about 1-2 minutes on a recent laptop.
- Check the protection score, then download the protected PNG and post that version.
Honest limits
- It is aimed at AI photo editors built on Stable Diffusion. It does not reliably stop ChatGPT, Gemini or face-swap apps.
- Screenshots, heavy compression and resizing weaken it. Post the downloaded PNG where you can.
- No tool can make a photo impossible to edit. Combine it with private accounts and posting fewer close-up face photos.
