A privacy VPN browser extension that rewards you for contributing data
Encrypts and masks your Chrome browsing traffic without requiring a separate desktop VPN client.
Aims to reduce the exposure of your IP and browsing pattern to network-level observers and trackers.
Connects the extension to LayerAI's program so users can earn DATUM tokens for contributing data as a node.
Install from the Chrome Web Store and enable or disable protection directly from the browser toolbar.
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.
