ON ATTENTION

The art of
noticing.

The most interesting ideas rarely arrive with an announcement.

They’re tucked into the things we read, the places we pause, and the details we almost pass by.

Give a thought a little space. You might find it has more to say.

Your browser. With a little more you.

Don’t just read it.
Make it yours.

A sentence worth saving. A diagram worth circling. An idea that needs a note. There’s room for all of it.

01 / MARK

Think outside the text selection.

Draw freely over a page. Choose your colour, thickness and opacity. Hold at the end of a stroke to straighten it, or erase just the bit you want to change.

02 / REFINE

A good mark can get better.

Edit an existing highlight’s colour, thickness or opacity. Undo, redo and keep going. Switch back to browse mode whenever you want to follow a link.

The thought behind the highlight

Give your
ideas a place
to land.

Click a highlight with the text tool to add a note in a floating glass pane. Save it, then hover to bring the thought back. Move away, and the page is yours again.

Notes and unfinished drafts save locally.
