Capture sentences that move you. Scan book pages, save meaningful quotes, and turn them into beautiful shareable cards. Your personal library of words worth remembering.
Some sentences deserve more than a fleeting moment. indexx is a reading companion built for people who underline, dog-ear pages, and return to the words that changed how they think.
CAPTURE SENTENCES THAT MATTER
Photograph a book page and let OCR extract the text instantly. Or type it in yourself. Either way, every sentence you save is linked to its book, page number, and your personal reflection on why it mattered.
TURN QUOTES INTO SHAREABLE CARDS
Transform any saved sentence into a beautifully designed quote card. Choose colors, adjust layout, and share directly to Instagram, Messages, or anywhere you want. Make your reading visible.
TRACK YOUR READING JOURNEY
Add books by scanning their barcode or searching by title. Mark what you want to read, what you're reading now, and what you've finished. Rate, review, and see your reading history at a glance.
YOUR PERSONAL SENTENCE LIBRARY
Browse all your captured sentences in one place. Each one carries the book it came from, the page you found it on, and the thought you had when you read it. A timeline of your reading life, built one underline at a time.
