Secure crisis hotline
for the people who need it
Llámenos is open-source hotline software that protects callers and volunteers. Encrypted notes, real-time call routing, and a zero-knowledge architecture — so sensitive conversations stay private.
Built for crisis response
Everything a hotline needs — call routing, encrypted note-taking, shift management, and admin tools — in a single open-source package.
End-to-end encrypted notes
Call notes are encrypted with per-note forward secrecy — each note uses a unique random key. Your secret key is PIN-protected and never leaves your device.
Parallel call ringing
Incoming calls ring all on-shift volunteers simultaneously. First pickup wins. No calls missed.
12+ languages built in
Full UI translations for English, Spanish, Chinese, Tagalog, Vietnamese, Arabic, French, Haitian Creole, Korean, Russian, Hindi, and Portuguese.
AI transcription
Whisper-powered call transcription with end-to-end encryption. Admin and volunteer can toggle independently.
Spam mitigation
Voice CAPTCHA, rate limiting, and real-time ban lists. Admins toggle protections without restarting.
Mobile-first PWA
Works on any device. Installable as an app. Push notifications for incoming calls.
See it in action
A modern, responsive interface designed for crisis response. Works on desktop and mobile.
Real-time overview of active calls, volunteer presence, and shift status.
Multi-channel architecture
Voice, SMS, WhatsApp, and Signal — all routed through a unified platform with your choice of provider.
Honest about security
We publish exactly what is encrypted, what isn't, and what the server can see. No hand-waving. Your secret key is PIN-encrypted and held only in memory when unlocked. Per-note forward secrecy means compromising a key can't reveal past notes. Link new devices securely via QR code. Read the full security model to understand our threat landscape.
