Free AI detection tools for deepfakes and social engineering
Diopter helps security teams defend against real-time social engineering, and these free AI detection tools let you check a file, size your fraud risk, or test your own eye with nothing to install. The first check on the site is free with no sign-up, and the free tier gives you 5 scans a day.

Open in ChatGPTWhat do the free tools check, and what does live-call defense add?
The free tools check a file after the fact, such as a voicemail, a screenshot, or a clip someone sent you, using the same detection as the live product. The attacks Diopter is built for happen on live calls, where the face and the voice can be generated in real time and the pressure comes from the conversation. On those calls, Diopter verifies the caller's identity, scores the voice and video, reads the conversation for pressure, and checks requests against your policy, then gives the person on the call a real-time alert. We also run agentic social engineering simulations, so you can test your people with cloned voices and deepfake video before a real attacker does.
Two ways to start
Your first agentic attack is on us. Fill out the form, and we'll run a simulated attack on one of your teams at no cost. Want to see live-call defense instead? Book a walkthrough, and we'll replay a real attack and show you what Diopter caught and when.
A free simulated attack on a team you choose, with an NDA first if you want one.
Questions about the free AI detection tools
Can Diopter test our team with a simulated attack first?
Yes. We'll run one simulated attack on one of your teams at no cost, using a cloned voice or deepfake video if you'd like. Most teams start there, then add real-time alerts on their live calls.
Are the AI detection tools free, and do I need to sign up?
Yes, they're free. Your first check on the site doesn’t need a sign-up, and after that the free tier gives you 5 scans a day. In Claude and ChatGPT, you'll connect a free Diopter account with the same daily limit. Live-call defense for teams is the paid product.
What is the most effective way to identify a deepfake?
Use a detector, such as Diopter's, that scores the whole file for signs of AI generation and gives you a confidence level. Visual tells such as flickering hair edges, lip movements that trail the words, and a face that won't turn sideways are worth watching for, but a good fake may show none of them.
Can I check whether an audio clip or voicemail is AI-generated?
Yes. Diopter's deepfake audio detector takes a voicemail, a call recording, or a voice message and scores it for cloning and text-to-speech traces. Upload the file or paste a link, and you'll get a result with a confidence level.
What if I need more than 5 scans a day?
We can add more credits. Contact us with your work email and roughly how many scans you need, and we'll get back to you.
