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!

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.

Finally. There’s an app for this!

Time saver! I’ve finally found an app where I can highlight the sh** out of everything I research and easily share the most important content with collaborators. This is also an awesome tool for someone like me with ADHD in addition to a few learning disorders. I have been waiting for an app like this for way too long. It’s so easy to use and navigating this app doesn’t distract you from the writing like some apps that have way too many cluttered or hidden functions. I LOVE THIS! And the comment feature is the BEST because it’s right beside the highlighting button so there’s no back and forth AND the comments show up under your highlights on the webpage. And the different highlighter colors are perfect for breaking down my highlighted notes into separate categories. I used to use 3 apps to do what this 1 app does in a click or two. Nice work guys! Thank you.


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'.

Great in many ways, stinks in one specific way

Liner is an amazing app, I use it for exactly what it was made for: highlighting websites. I would give it a higher review however, if there was some mechanism so that you could go back to the place in the webpage where you left off on your last highlight. As it is now it takes you to the very top of the webpage that you were working on, with no way of going to the location of the most recent or any highlights for that matter. If you were to make that change I would definitely improve my review.
