Lightbulb AI App

Lightbulb is a native iOS custom keyboard extension that integrates advanced AI writing, summarization, and memory directly into any iOS app — WhatsApp, Slack, Mail, Instagram, LinkedIn, Threads, and X. Users no longer need to switch back and forth between ChatGPT and their chat apps.

• AI Writing & Quick Rewrites: Transform rough notes or bullet points into polished, professional emails and messages with 1 tap.
• Zero App Switching: Your intelligent writing assistant lives directly inside the iOS system keyboard across all third-party apps.
• Quick-Tap Saved Shelf: Pin frequently used replies, outreach scripts, addresses, and hashtags to the keyboard shelf for instant reuse.
• AI Memory & Tone Adaptation: Learns your personal communication voice and adapts formatting style for specific platforms (WhatsApp, Gmail, LinkedIn).
• Smart Thought Nudges & Reminders: Schedule follow-up alerts and thought reminders directly as you type so important client conversations are never forgotten.
