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 and transcripts are encrypted client-side before leaving the browser. The server only stores ciphertext.
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.
Honest about security
We publish exactly what is encrypted, what isn't, and what the server can see. No hand-waving. Voice calls still traverse Twilio's infrastructure, and we say so upfront. Read the full security model to understand the threat landscape and our roadmap for closing gaps.
