Turn any webpage into bilingual reading in one click
Add translations to any webpage with a single click, keeping the original text in place alongside the translated version.
The no-cost plan runs on Google Translate and covers 32 languages, which is enough for everyday reading of many popular languages.
The paid tier uses AI models that understand context, so idioms and culturally specific phrasing come out natural instead of literal.
Displays your native language only where you need it, turning authentic pages into study material without overwhelming you with full translations.

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.
