Lightbulb: AI Keyboard & Chat

Lightbulb is the AI keyboard and AI assistant that works natively in every app you type in, with no app switching. Instead of copying text into a separate AI chat app, Lightbulb brings AI chat, AI writing, rewriting, editing, and saved messages directly into your AI keyboard. Use it in messaging apps, social apps, email, notes, work tools, and anywhere the keyboard appears. Ask a question, get an answer, select the response, and turn it into a full post. Rewrite a message before sending it. Fix grammar in place. Make text clearer, shorter, friendlier, more professional, or more engaging, all without leaving the app you are already using.． Lightbulb is built for people who want an AI assistant to feel native, fast, and available everywhere.
