Privacy-first, AI-powered Android keyboard that rewrites any text in any app with one tap.

AutoKeyboard sits inside your Android keyboard and rewrites your messages in any tone: Professional, Flirty, Poetic, Gen-Z, Shakespearean, or your own custom style. Works in WhatsApp, Gmail, Instagram, and every other app.

• 9 Tone Presets — Professional, Friendly, Casual, Flirty, Witty, Poetic, Gen-Z, Formal, Custom
• Custom Prompts — "Talk like my GF" or "Make it Shakespearean"
• 10 Cloud Providers — OpenAI, Gemini, Claude, Mistral, Groq, Cohere, OpenRouter, DeepSeek, Together AI, Custom
• 5 On-Device Models — Gemma, Phi-3, Qwen, Llama 3.2, MLC (fully offline)
• Fallback Chain — Automatic failover across configured providers
• Zero Message Storage — No text is ever stored or logged
• Encrypted API Keys — AndroidKeyStore + EncryptedSharedPreferences

• Encrypted secrets — API keys stored via EncryptedSharedPreferences + AndroidKeyStore
• No cloud dependency — Can run fully offline with on-device models
• Open source — Full code audit possible
