It's a great. Fills a problem I've had for years. Lots of things that could make it even better: Spelling suggestion in the ideas area, improve the extraction (difficult to take one handed photos, come on!), better extraction tools, like orientation by degree and auto removing line breaks, be able to extract text for quotes, makes no sense how you are doing it, allow to choose if you want to write an idea, a task or use it as a quote, allow me to submit book covers, highlighter on photos

Hey there! Thank you for the review. Indeed, Underline needs more work, but we are getting there. A few of your requests are already on our list but if you have other ideas to better the app, send us a note to hello@getunderline.com. We really appreciate your feedback. Thank you!

As Joachim mentioned, this is a good idea. The problem is, unless one has the book on Kindle whete one has already taken notes, the photo scan one takes of a page is not accurate and requires a lot of one-fingered typing to correct and save the page. To do that the system also has to download all of one's books on Kindle. For a sudent or researcher, note-taking by hand is much faster. The advantage of this sysyem if one has the time would be keeping non-Kindle notes in a digitized format.

Thank you, Mary! We're sad to hear you had to correct the text extracted through scanning. Please make sure you're updated to the latest version, we're improving the quality of the text extraction constantly, it should be perfect. Can you please explain what you mean by "To do that the system also has to download all of one's books on Kindle."?

The ad I saw for this app made it seem like it would be able to detect and extract highlights I had added to the pages of a book, but it simply recognizes entire text of the page in the photos I take, and I have to select the highlight manually and delete the rest. Feels like duplicate work. The idea is good, but the execution needs to be refined.

Hey Waldir. At the moment, Underline is an app that helps you save your favorite ideas but it won't recognize the manually highlighted text. We encourage you to directly save the text you want with Underline . Also, if you think that Underline is a great app, could you perhaps consider increasing your review? Thank you and have a great day! 😁
