The product
One protection, across three surfaces that work together.
Prevyber is a mobile app that reads the language of scams the moment it appears and turns it into a simple alert. The same analysis lives in three different ways, depending on how the user wants to reach it.
Vigil, the system
It runs in the background and, when it recognizes a risk on the screen, shows an alert over any app: a green, amber or red signal, with a simple explanation and a clear action. In normal use it is invisible: it does not interrupt, it does not notify. It activates only when needed.
Sage, the conversation
The surface where the user asks in natural language and gets an analysis or a piece of advice. It is the place to bring a message, a link or a doubt and get a clear answer.
The Tools
Standalone modules the user opens for a deliberate check: a suspicious message, an article, a website, their own credentials. The same capabilities as Vigil, but on demand.
The dual mode
The user does not have to wait for an alert to be protected, nor open the app to run a check.
The same features, from spotting scams in messages to checking an article or a website, all the way to managing credentials safely, work in two ways: automatic, when Vigil calls them on the content that appears on the screen, and manual, when the user opens them to check something specific. Coverage runs from messages to calls, from browsing to identity.
Why people stay, beyond the single alert.
Scams are not a daily event, but the risk is constant. Frequently used features, such as managing credentials at login or checking content, create a daily habit. Vigil, meanwhile, stays active in the background. After a few weeks the question is no longer whether the app is useful, but whether you are willing to remove it.
