# Welcome to Coreply

> AI-powered texting suggestions that finish your sentences — right inside your favorite messaging apps.

Coreply is an Android app that watches what you type and suggests how to finish your message in real time. It works inside WhatsApp, Instagram, Signal, Telegram, and 15+ other apps — no copy-pasting, no switching windows.

Connect your own AI provider or use Coreply Cloud to get started in minutes.

## How it works

<Steps>
  <Step title="Install the app">
    Download the latest APK from the [releases page](https://github.com/coreply/coreply/releases) and install it on your Android device (Android 8+).
  </Step>

  <Step title="Choose a provider">
    Sign up for [Coreply Cloud](https://coreply.up.nadles.com/) for instant access, or enter your own API key from any OpenAI-compatible provider.
  </Step>

  <Step title="Enable the service">
    Toggle on Coreply in the app and grant the accessibility permission when prompted.
  </Step>

  <Step title="Start typing">
    Open any supported messaging app and start typing. Suggestions appear automatically — tap to insert a word, or long-press to insert the full suggestion.
  </Step>
</Steps>

<Note>
  Coreply sends conversation context directly to your chosen AI provider. No data passes through intermediate servers (except when using Coreply Cloud).
