Yes, both Bark and Canopy can detect sexting to some extent. Bark actively scans for nude photos in texts, emails, and social media DMs using image recognition algorithms. It will send alerts for any explicit imagery found on your child's device. Canopy takes a more limited approach by filtering out inappropriate images only as they appear on-screen. It does not scan incoming or outgoing sexts across apps. But any nude selfies or pornographic pictures will be automatically blocked from view. So for the most robust sexting detection, Bark is preferable. But Canopy offers a degree of protection by restricting explicit imagery.
