The same clean reading view, with the section map, on the page you already opened.

## Clean reading on any page

The same calm, readable view the web app gives you, on the page you already opened. No clutter, no pop-ups competing for the text.

## The section map in place

## Inline explanations

Passive marksDefineWhat you flag while reading, kept with the reason it mattered rather than as a highlight in a folder you never reopen. on the hard parts: a source, a definition, a short expansion, revealed as you pause.

## Listen along

Hand any page to the standard voices and listen while the words follow along.

## Keep it in place

Structure it and mark it where you found it. The page becomes a piece you keep, already mapped, without sending it anywhere first.

## Every kind of page

Articles, posts, long reads, documentation. The extension works across what you actually read on the web.
