v1.0 – November 2025
"Your data never leaves your phone. Your thoughts are yours."
MindPlex was born from a simple but radical belief:
You should be able to have deep, multi-model AI conversations without ever trusting a third-party server with your history.
In an era where every AI chat app uploads your entire conversation to the cloud (often forever), MindPlex does the opposite:
| What the industry does | What MindPlex does |
|---|---|
| Sends full history to remote servers | Sends only one message at a time (or full only when you explicitly ask) |
| Stores your chats in the cloud | Stores everything locally (encrypted Room DB) |
| Uses your data for training | Zero data collection — not even analytics |
| Requires account & login | Works offline-first — just enter your OpenRouter key once |
| Locks you into one provider | Lets you choose any model on OpenRouter — 15+ models with one key |
-
Single OpenRouter Key Architecture
No AI1/AI2 split. No multiple provider keys. One OpenRouter key = access to Claude, Gemini, Llama, Grok, Moonshot, Cerebras, and 10+ more. -
Local-First Continuation
Every debate, collab, solve, or code session is saved locally.
You can exit, close the app, come back days later — and continue exactly where you left off. -
Privacy-by-Default Context Window
- Default: Only the last AI response is sent with your new question
- Explicit request ("review entire discussion") → full history sent (user-controlled)
-
Tier System Without Lock-in
- Free: 2 fixed models
- Pro/Business: Choose up to 4 / all 15+ models
- 14-day full Pro trial on first key entry
- Gumroad keys or self-generated — no Google Play billing dependency
-
No Background Phoning Home
- NetworkSecurityConfig blocks all domains except OpenRouter
- No Firebase, no Crashlytics, no analytics
- No debug logs in release builds
- 100% Jetpack Compose UI
- EncryptedSharedPreferences for API key
- Room + Flow for conversation persistence
- KSP for future Brain feature (search & analysis across all sessions)
- ProGuard/R8 hardened release builds
- Voice input in all modes
- Stop button + pinned topic + session resume
Coming 2026:
- Cross-session search ("Show me every time I discussed productivity")
- Insight extraction ("What are my recurring themes?")
- Automatic tagging of conversations
- Mind map view of all your thinking
- Export to Markdown/Obsidian/Notion
All 100% local, encrypted, private.
MindPlex is not just another AI chat app.
It's a statement.
In a world racing to centralize your mind,
MindPlex is the tool for those who refuse to give it away.
Your thoughts. Your device. Your rules.
