Someone to talk to,
that never leaves your phone.
NilaMind is a free, open-source companion for the hard days — anxiety, low mood, the times you can't open up to anyone. Nothing you say or type leaves your device — no account, no backend.
Free and open source, for Android. On first run it downloads its on-device AI model (~1.1 GB, over Wi-Fi); after that it works fully offline — voice included.
Your conversations never leave your phone.
There's no account, no server, and no analytics. The model that powers Nila runs on your phone, so your chats, notes and mood stay with you — stored encrypted, yours to delete anytime. Even your voice: speech-to-text runs on-device by default, so nothing you say leaves the phone. (An optional setting can use your phone's system recognizer for extra accuracy.)
Why I made this
I built NilaMind, from my own lived experience, for the nights when you can't open up to anyone — a steady, private voice that's just there. It isn't a product or a replacement for real care; it's a tool I needed, shared openly in case it helps you too. That's the whole reason it never sends your words anywhere: help is the only metric — never gather data at any cost.
What's inside
A companion, on-device
Talk to Nila by voice or text — she listens first, with a short, warm reflection. Then the app quietly offers the right evidence-based skill (CBT, DBT, ACT, self-compassion) for the moment, one tap below her reply.
Private by design
No backend, no telemetry, no data collection. The app's only network use is a one-time model download — after that it works fully offline, including voice, which is transcribed on-device by default. (An optional setting can use your phone's system speech-to-text for extra accuracy.)
A safety layer that doesn't trust the AI
A separate, on-device crisis check surfaces real help and points you toward a person — independently of the model.
Tools that actually help
Short, evidence-based skills, private journaling, gentle check-ins, and a nudge back toward real human connection.
Please read this first
NilaMind is an early research preview and a self-help tool — not therapy, not a medical device, and not a crisis service. It can be wrong. It is not a substitute for professional care or human connection.
If you may be in danger, contact local emergency services now. Find a helpline anywhere at findahelpline.com · US: call/text 988 · India: Tele-MANAS 14416. A piece of software is not a reliable way to reach help in an emergency.
Get it
NilaMind is an Android app. Two ways to install it — both use the same signed release, so you can switch without reinstalling.
Android 7.0+ · Obtainium installs NilaMind from GitHub and keeps it updated automatically — or grab the APK directly. The first run downloads Nila's on-device AI model (~1.1 GB, Wi-Fi): the entire AI lives on your phone, which is exactly why nothing you say or type ever leaves it — voice is transcribed on-device too. One-time download, then fully offline. Also coming to IzzyOnDroid.
- Recommended: install Obtainium, then add NilaMind with the button above — it handles installing and future updates for you.
- Or download the
.apkdirectly and let your browser/file manager install it (Android will prompt). - Open it, set up, and let Nila's brain download once over Wi-Fi. The very first reply after opening can take a moment on a slower phone — it's loading the model, not thinking; every reply after that is fast.
Open source
NilaMind is Apache-2.0 and built in the open. Read the code, the safety design, and the full docs — or build it yourself.
