Getting to know the reader
Android · iPhone · quillo.trUpdated:
The top bar is the colour of the background and kept simple: the back arrow on the left, the document name in the middle with the page counter below it ("Page 3 / 40"), and only ⋮ (More) on the right. There are no other buttons; everything is on the dock and in the ⋮ menu.
The Ai orb sits in the right corner of the top bar (tap: chat, press and hold: voice mode). A glass dock floats at the bottom of the page: the mode capsule (Listen · Markup · Notes). While listening, a playback row is added below the dock. When Markup is on, its toolbar sits just above the dock; listening doesn't stop. Tap Markup again to close the toolbar; tapping Listen or Notes also closes it and switches straight to that mode.
A document is prepared the first time it opens ("Opening PDF…", "Reading page 1 / 40…"). On scanned pages the text is recognised on the device; this happens once per document and the result is kept.
The page you stopped at and the sentence you were listening to are remembered for each document; open it again and you continue from there. The sentence being read is highlighted in turquoise, and with a cloud voice the word being read is underlined.
The back arrow and the phone's back button return to where you opened the document from: the same folder if you opened it from a folder, the same search if from a search (see "Back and Home").
