Liner is fantastic for streamlining my research! The ability to highlight web pages and PDFs directly has made my information gathering so much more efficient. I particularly love how easy it is to organize my highlights into folders."

Tried the professional version, wouldn't cooperate. Why are you giving me bulleted points when I asked for a simple essay? Also you can RARELY get a complete response because it's ALWAYS "something went wrong. please try again" by the 6th time, I gave up.

New app version is confusing. Hitting back button always closes the app which is frustrating. They're trying to make some kind of browser and it's wayy too complicated. There's not one but three rows of menu bars in addition to whatever you're trying to read. Now there's no way to browse highlights because when you look at one highlight it resets you to the top of your highlights list, so you can't browse highlights anymore, which was the entire point of this app. I just want a highlighter app!
