Question: I'm a public figure looking for a way to protect my online presence from fake accounts and unauthorized content use.

One of the most ambitious is Loti, a service geared specifically for public figures like you. It offers Watchtower, which screens for fake accounts, endorsements and deepfakes, daily. It also offers Vault for licensing content and No Fakes to eliminate bogus social media accounts. Loti's automated takedown engine has a 95% success rate in 17 hours, it says.

Another good option is Axur, a cybersecurity service that uses AI to monitor for and remove digital threats on the Deep and Dark Web. It's got serious brand protection tools, AI-powered takedowns and deep and dark web monitoring. That makes Axur a good option if you're worried about outside cyber attacks and online piracy.

If you're just interested in deepfake detection, AI or Not has an AI detector that can quickly identify deepfakes and generative AI content. It's got a variety of detectors for images, audio and identity documents, which can help thwart fraud and disinformation. It offers flexible pricing options for individuals, small businesses and enterprises.
