The fastest way to get started is Coreply Cloud — no API account needed. You sign up, copy an access key, and you’re done. If you prefer to use your own provider, follow the OpenAI-compatible path in step 2.
1

Open Coreply

Launch Coreply from your app drawer after installing it. The main screen shows the service toggle and your current provider settings.
2

Configure your AI provider

Scroll to Custom API Settings in the app and fill in three fields:
FieldDescription
Base URLThe OpenAI-compatible endpoint for your provider (e.g. https://api.groq.com/openai/v1/)
API KeyYour provider API key
Model NameThe model identifier to use (e.g. gemini-2.0-flash, llama-3.3-70b-versatile)
Using Coreply Cloud (recommended for new users): Sign up at coreply.up.nadles.com, copy your access key, and paste it into the API Key field. Leave the Base URL and Model Name at their defaults unless the dashboard instructs otherwise.See AI providers for per-provider setup guides including exact URLs and recommended models.

Enable the Coreply service

Toggle the master switch in the app to On.Android will prompt you to grant the accessibility permission. Tap Allow and enable Coreply in the Accessibility settings screen.
The accessibility permission is required. Coreply uses it to read on-screen conversation text and position the suggestion overlay above the keyboard. Without this permission, no suggestions will appear.
4

Open a supported messaging app and start typing

Open WhatsApp, Signal, Instagram, Telegram, or any other supported app and navigate to a conversation. Begin typing a message — the Coreply suggestion overlay will appear after a brief pause.
5

Interact with suggestions

  • Single tap a suggestion to insert the next word into your message.
  • Long press a suggestion to insert the full suggested text at once.
Suggestions update continuously as you type, so you can keep typing and a new suggestion will follow.
