Immersive language learning in your browser with one-click Anki cards
Understand how a word is used in a specific sentence from the page or video you are reading, rather than relying on a generic dictionary definition.
Send words, pronunciations, phrases and full example sentences to Anki without leaving your reading flow.
Watch videos in your target language and pull vocabulary directly from the subtitles and content on screen.
Choose between GPT-4, Claude, local Ollama models and free online dictionaries, so you can match cost, privacy and quality to your needs.
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.
