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.
AI-powered Chrome extension that scores any text for truthfulness
Submit any block of text and receive a clear true or false label back in the browser.
Each verdict arrives with a confidence score so you can judge how decisive the model was.
Uses advanced large language models rather than a static keyword blocklist to reason about claims.
Lives in the Chrome toolbar as a small 146 KB extension, so checks happen without leaving the page.
