Sendright: The AI Keyboard
Sendright is an intelligent Android keyboard application and mobile productivity companion published on the Google Play Store, engineered to transform everyday mobile typing with real-time generative AI assistance, tone shaping, and grammar enhancement across WhatsApp, Gmail, Slack, and Instagram.
Operational Friction & Legacy Bottlenecks
Mobile users frequently struggle with crafting articulate messages, professional emails, or witty replies on the go. Traditional mobile keyboards only offer basic dictionary autocorrect. Sendright needed an ultra-low latency on-device input method editor (IME) that seamlessly communicates with advanced AI inference engines without compromising battery life, typing speed, or user privacy.
Modern Engineered Architecture
Vaynex engineered and optimized the high-converting web landing platform and mobile product architecture for Sendright. The app integrates directly into the Android InputMethodService lifecycle, offering one-tap prompt rewriting, tone modulation (Professional, Casual, Witty, Concise), instant language translation, and privacy-first typing pipelines, accompanied by a sleek Framer landing site.
