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.

This app is literally THE BEST APP I have ever used, it literally saved my life and still saving it! It is literally such a life savor! BUT the only thing I don’t like about it is that it has only 2 color options.. if the people who made this app could probably fix this issue and make all the colors free it would be AMAZING. IT WOULD LITERALLY BE THE BEST APP ON PLANET EARTH. But I hope the creators would put this as an idea for the future :)

Awesome idea - want this to succeed

I really love the concept of this service and it does seem to be continually getting better. However my biggest gripe is that the actual mechanics of highlighting are very problematic to the point of complete frustration. On either MacOS or iOS it is painful trying to select the exact text you want to highlight. Far too often it selects the entire page which is NOT what you want. Now perhaps this is dependent on the way the content you are trying to highlight is formatted but it seems to me there should be a safety mechanism that stops the runaway highlighting and some kind of deceleration to give you finer control. If Liner’s devs can fix this problem they will have a winner for sure.

Needs work

Man, you all are almost there. Some if not all of the drawbacks may not be your fault. If this app worked like I thought it would, it may very well change my life. I'm plagued by valuable information I've saved, but don't remember which bookmark/browser/app/notebook/device & on & on & on.

However, selecting text in iOS chrome/pocket did not present the yellow dot option from the demo. After toggling Liner on, I'm presented with this error: "Share web page or URL to Liner to start highlighting. Using only sentence or image is blocked by Apple".

If I need to open/share across several different apps, it defeats the purpose for me. 5 stars for a brilliant idea, minus 2 for poor integration execution.

Developer Response ,

You can open/share across almost every different apps. Please tap LINER button in the share menu on the 'Page share sheet' not on the 'Tooltip share sheet'.
