An AI knowledge base that emails you what you read yesterday
Save web pages, text notes, images, YouTube videos and podcasts into a single personal knowledge base, so your reading and watching live in one place.
Ask questions to your saved knowledge base and get answers grounded in the material you have collected rather than the open web.
Explore a visual map of how your items relate and mine the collection for connections, themes and blind spots you might have overlooked.
Get a daily newsletter of what you read yesterday, or listen to it as a podcast. A lightweight way to review and retain what you have learned.
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.
