Okay LINER for Chrome is getting seriously useful. highlight any webpage, one-click export to Evernote. I'm telling you Evernote & Pocket, whoever acquires LINER will win the read-it-later wars. People LOVE highlighting!
― Tiago Forte (Productivity Consultant)

I have been thinking for about 2 years on a better way to highlight, collect, and share quotes/insights you find surfing the web or reading a book. There is so much information on the internet that it’s crucial to find ways to filter and curate the most relevant content.

I just had a tiny tech-gasm. Thank you so much. I finally can have both & won't be switching between Instapaper & Pocket anymore. You guys have already earned 5 stars. I've never seen this level of customer support and interaction.

Gets better all the time


I have used the free version since the beginning. I have seen continuous improvement on both my iPhone and desktop. I upgraded to the premium version to support the continuous improvement of the app. I expect to see some great improvements this year and like to support the developers. On both my iPhone and desktop it works smoothly. I have tried other services, but this one is the best.

Great idea but needs some bugs fixed


This is a fantastic idea for an app. It does a great job of taking any webpage and turning it into something that can be highlighted and annotated. However, there are some bugs. You can quickly highlight any complete sentence or you can highlight individual words easily. However, if you wanted to highlight a segment of a sentence, it does not allow you to do so. Also, only one color is allowed in the free version, and I think at least two colors would be nice.

unable to use


For several months now I’ve gotten an odd error message when I try to import web pages to Liner and also now just trying to open Liner.

It tells me “Liner Unavailable” under construction.

EDIT: the app started working finally, after it seemed to log me out and start fresh. One thing I dont like is the requirement of premium to have more than one color of highlighter. the other benefits to paying premium don’t seem worth a monthly subscription.
