Your team's SOPs, manuals and know-how in one AI assistant
Put a question to an AI assistant that has indexed your company documentation, SOPs and equipment manuals for fast on-the-job answers.
Turn centralised documentation into clear, repeatable processes team members can follow when they need more direction.
Give new hires a clear roadmap plus short quizzes and badge tracking that build and measure industry expertise.
Translate documentation so team members read directions in their preferred language, based on their mobile device settings.
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.
