Key features
- Real-time suggestions — the overlay updates as you type, showing context-aware completions drawn from the current conversation.
- 20+ supported apps — includes WhatsApp, WhatsApp Business, Telegram, Nekogram, Instagram, Signal, Discord, Hinge, Tinder, LINE, Snapchat, Facebook Messenger, Google Messages, Microsoft Teams, Mattermost, Viber, Heymandi, Beeper, ChatGPT, Perplexity, and Android notification replies.
- Bring your own AI provider — connect OpenAI, Google Gemini API, Google Vertex, Groq, OpenRouter, Azure OpenAI, xAI, Mistral, MiniMax, Vercel AI Gateway, or any OpenAI-compatible endpoint.
- Coreply Cloud — a hosted option that requires no API key setup. Sign up and paste a single access key.
- No data collection — when using your own provider, conversation data travels directly from your device to the inference API. Nothing passes through intermediate servers.
- Open source — licensed under the GNU AGPL v3.
How it works
Coreply runs as an Android accessibility service. When you open a supported app and start typing, Coreply reads the relevant visible text and your current draft, then sends a prompt to your configured AI provider. The response is trimmed to remove text you have already typed, and the remaining suggestion appears in a floating overlay above the keyboard.- Single tap on a suggestion to insert the next word.
- Long press to insert the entire suggestion at once.
