Strata is an AI keyboard for iPhone. Instead of switching to ChatGPT and copy-pasting, the AI lives inside your keyboard. Works in any app — iMessage, Slack, X, Instagram, anywhere you type. What makes it different: • Custom keyboard with swipe typing, not a chatbot • Per-app conversation threads that persist for days • Dictate prompts via Siri — Strata captures them • Multi-option responses — pick and insert in one tap • Powered by Google Gemini • Streaming real-time responses
