About this app

Scams don't always give you time to stop and think.

Lethi gives you live protection when something suspicious appears, helping you spot potential scams, understand the risk, and decide what to do before taking action.

Whether it's a suspicious message, link, notification, screenshot, image or audio, Lethi helps you understand what you're dealing with.

Live protection when it matters

Lethi can detect signs of risk as suspicious activity appears and alert you when something may need your attention.

For higher-risk situations, Lethi can step in with a clear warning so you can check what happened before continuing.

Instead of leaving you with a generic alert, Lethi explains:

• How risky the situation appears
• What warning signs were detected
• Why those signals matter
• What you can safely do next

Check anything you're unsure about

You can also ask Lethi directly whenever something doesn't feel right.

Check a:

• Message
• Link
• Screenshot
• Image
• Audio

Lethi analyzes the situation and gives you a simple risk level: low, medium or high.

Understand the warning signs

Lethi can help identify signals commonly associated with scams and social engineering, including:

• Urgent requests for money
• Requests for passwords, verification codes or personal information
• Suspicious links
• Impersonation attempts
• Pressure to act immediately
• Emotional manipulation
• Requests to keep something secret

Know what to do next

Detecting something suspicious is only part of the problem.

Lethi gives you clear, actionable guidance based on the situation.

That may include not opening a link, avoiding a payment, not sharing sensitive information, verifying a request through an official channel, ending the interaction or asking someone you trust for help.

Someone you trust can be there too

Lethi lets you connect a trusted contact who can support you when a situation requires extra attention.

You decide what they can see and what permissions they have.

Your original evidence remains private by default and is only available to a trusted contact when you explicitly allow it.

Protection without surveillance

Lethi is designed to help you stay safer without taking control away from you.

Live protection is there when something deserves your attention. And whenever you're unsure, you can open Lethi and ask.

Understand the risk. Know what to do next.

Lethi can help identify signs of scams and suspicious activity, but no system can detect every scam.
