The AI keyboard that writes, translates and protects every message
Draft, rewrite, fix grammar and adjust the tone of messages in seconds, directly inside any app where you type.
Translate between 50+ languages while you type, so you can reply to international customers fluently.
One tap switches between professional, friendly, persuasive or apologetic tones, keeping your message appropriate for the context.
Generate social posts, ad headlines and email copy in your brand voice without leaving the keyboard.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
