Trevius

Your Personal AI Assistant, Everywhere You Go

Moving to a new country or traveling abroad shouldn't be a maze of stressful phone calls. Trevius is a smart AI assistant that makes local calls for you, speaks the language fluently, and gets things done while you focus on what matters. Trevius is a mobile application that helps users manage phone calls and automatically schedule events in their Google Calendar.

Why You'll Love Trevius

Break the Language Barrier

Need to book a table in Paris, see a doctor in Berlin, or call a plumber in Prague? Just tell Trevius what you need in your own language. It will make the call and handle the conversation perfectly in any of our 9 supported languages: English, Russian, German, French, Spanish, Italian, Portuguese, Czech, and Polish.

Real Conversations, Not Robots

Our AI sounds remarkably human. It understands context, handles interruptions naturally, and even catches local nuances. The person on the other end won't even know they're talking to an assistant.

Total Peace of Mind

Never worry about "did they understand me?" again. After every call, you get a full transcript translated back into your language. You’ll know exactly what was agreed upon, down to the last detail.

Hands-Free Scheduling

If Trevius books an appointment, it automatically syncs it with your Google Calendar and sends you a notification. Your schedule practically manages itself.

Save Time and Nerves

Stop wasting time on hold or struggling with automated phone menus in a language you don't know. Trevius handles the boring stuff so you can get back to enjoying your life.

How It Works

1
Pick a task: "Book a Table," "Medical Appointment," or create your own custom request.
2
Provide the details—like time, place, and your name—in your native language.
3
Trevius makes the call instantly. You can listen in real-time or just wait for the notification.
4
The task is done. You get a confirmation and a calendar invite. It’s that simple.

Permissions and Data Usage

Trevius may request permission to access your Google Calendar in order to create and manage calendar events when appointments are scheduled during calls handled by the assistant.

Calendar access is used only to create, update, or delete events explicitly requested by the user.

Trevius does not read unrelated calendar events, does not analyze calendar data, and does not share Google Calendar data with third parties.

Users can revoke access to their Google account at any time through their Google account security settings.
