How Lumen works
It's a browser first.
Open any page and read it the way you would anywhere else. In the background, Lumen saves the text, indexes it and sorts it by topic, all on your phone.
Your reading sorts itself.
Pages collect into coloured folders by topic, such as climate, design, film and science. Lumen names and fills the folders for you, and so the library grows as you read.
You decide what it keeps.
The site menu counts the trackers Lumen blocked on each page. When you would rather it keep nothing, one tap turns off Collect Knowledge.
