AI engine running on your Android phone

Your phone,
on autopilot.

Idan AI is a personal assistant that runs entirely on your device. Tell it to reply to an email, send a WhatsApp, search the web, or set a reminder — and a local engine inside Termux handles it while you do something else.

No cloud subscription. No third-party servers processing your messages. Just a lightweight app paired with a powerful engine on the phone you already carry.

How Idan works

Two pieces, one phone. The companion app is what you talk to. The Termux engine is what actually does the work — quietly, locally, on your device.

01

You say what you need

Type or speak a plain-language command in the Idan companion app. No menus, no workflows — just say it.

02

The engine acts on your phone

The Termux engine running on the same device reads your command, connects to Gmail, Docs, WhatsApp or search, and executes the task.

03

Done — without the noise

You get a result. Replies drafted, reminders set, searches run. The engine waits silently for the next task.

Android App (APK)

The interface

Handles onboarding, commands, engine status, and logs. Requests no sensitive permissions — no microphone, contacts, or accessibility service.

Local HTTP
127.0.0.1:3788
Termux Engine

The worker

Node.js server running inside Termux. Executes every task — mail, search, documents, automation. Auto-restarts on crash or reboot. No cloud needed.

What it handles

One assistant, nine capabilities

All of these are executed by the Termux engine on your own phone — not a remote server, not a SaaS API middleman.

Gmail

Read threads, rank urgency, draft replies, auto-respond while you're in meetings, and send — all hands-free.

📄

Google Docs & Sheets

Create documents, update spreadsheets, and query data through the engine without opening the app.

💬

WhatsApp

Reply to the latest notification, send a message, or set a do-not-disturb auto-reply — from a single command.

🔍

Search & Scrape

Local index runner and web scrape workers run inside the engine, surfacing answers without a browser.

🗓

Reminders & Tasks

Engine-side job scheduler sets timed reminders and recurring tasks — no exact-alarm permissions required.

🧠

Memory & Planning

Persistent state stored engine-side. The assistant remembers context across sessions and surfaces summaries in the app.

Privacy first

Your data never leaves your phone

The engine runs at 127.0.0.1:3788 — a loopback address accessible only from your own device. No messages are processed by a third-party cloud. No usage data is collected. When you connect a Google account, that token lives on your phone and is used only by the engine you control.

The public APK requests no sensitive Android permissions — no microphone, no contacts access, no notification listener, no accessibility service, no overlay.
