About this app

BrainUI is your real-time AI guardian — protecting you from scams, manipulation, and deception during calls and conversations.

GUARDIAN MODE
Listens live during calls and alerts you instantly when scam tactics, manipulation, or financial fraud are detected. Get a risk score, overlay alerts, and scripted responses — even when your screen is off.

SMART LISTEN
Capture any conversation in the background. Get AI-powered insights, key decisions, action items, and emotional tone analysis after every session.

TALK MODE
Record, transcribe, and analyse meetings or voice notes with a single tap. Powered by Deepgram and Claude AI for accurate transcription in 17 languages.

AUTO CONNECT
Zero setup required. AI keys are managed automatically — just open the app and start.

PRIVACY FIRST
End-to-end encrypted. All data stored locally on your device. We never sell or share your data.

BrainUI is designed for adults 18+ who want to stay protected in an increasingly deceptive world.

What’s new

Reminders, daily review, check-ins and the weekly digest now actually
arrive.
Smart Listen gives you a debrief even with no internet. Talk keeps
listening through your pauses. Guardian no longer stays alarmed after a
single word, Stealth mode is properly silent, and the Safe Word can
finally be set up.
