You highlight the best parts of a book, and a month later you remember almost none of them. Your Kindle highlights sit in a list you never open. Bloomind brings them back. Import your Kindle highlights in seconds, then revisit them in short daily sessions. Bloomind uses spaced repetition to bring each highlight back at the right moment, so it moves from "I read that somewhere" to "I know this". BRING YOUR HIGHLIGHTS IN - Kindle: export a book's notebook from the Kindle app on iPhone, Android or a Kindle e-reader, then share it to Bloomind. No Amazon login needed. - Pick the highlights worth keeping before you import them - Readwise: bring your whole library over with one CSV export, and choose which books to import - CSV: import notes from any other app - Share from anywhere: highlight text in any app, tap Share, then Bloomind - Every highlight is tagged with its book and author, like #meditations #marcusAurelius #book REVISIT THEM DAILY - Short review sessions: Bloomind shows a highlight and asks "Remember this?" - Answer honestly. Highlights you know well come back less often, and the ones you're forgetting come back sooner - Review everything, or revisit one book at a time - Keep a daily streak, so revisiting becomes a habit, not a chore - Watch your highlights become "mastered" and track your progress in every life area ORGANIZE THE WAY YOU THINK - Sort notes by life area (Mind, Growth, Career, Love, Body, Money and more) - Add your own notes, quotes and lessons from books, podcasts or your own reflections - Search by book, author or hashtag WHY SPACED REPETITION? Memory fades fast after we learn something new. Reviewing at increasing intervals is one of the most reliable ways to slow that forgetting down. Bloomind does the scheduling for you, so two minutes a day is enough. WHO IT'S FOR - Kindle readers with hundreds of highlights they never look at again - Readwise users looking for a simple, free way to review their highlights - Readers who want to remember and apply what they read - Anyone who collects lessons from books and podcasts FREE, NO SUBSCRIPTION Bloomind is free. Import a book tonight, review it tomorrow, and you'll be surprised how much stays with you. Kindle and Readwise are trademarks of their respective owners.
