Read more books, easier — key ideas from thousands of titles.
Each book is condensed into a short summary that captures its main ideas and takeaways, so you get the gist in minutes rather than hours.
Summaries come in multiple formats, including text, downloadable PDF and EPUB files, and audio, so you can read, save, or listen.
Browse by genre, author, trending, new, and themed lists, with dedicated Fiction and Nonfiction sections and a personally curated For You feed.
A personal library and import options let you save summaries, organise reading, and pick up where you left off across devices.
Your feeds, one calm stream — summarised, read aloud and filtered by AI.
Bring the RSS feeds you already follow into one clean, time-ordered stream instead of hopping between apps and tabs.
Every article gets a concise AI-generated summary so you can judge whether it is worth the full read.
Have articles read aloud so you can catch up while commuting, cooking or working out.
A daily AI-curated digest rounds up the most relevant items from your sources in one short briefing.
