Zero-Click Intelligence injected into every web page you open
Relevant keywords on any webpage are automatically underlined; hover to reveal live enterprise insights without leaving the page.
Cards pull securely from a wide range of enterprise systems to combine information from multiple business sources.
Apply alert thresholds so insight cards visually signal when a metric crosses a defined boundary.
Use insight cards as a starting point for cross-application workflows and share them with teammates.
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.
