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.
