KnowledgeSaved
Instant OCR capture
Snap a photo of a page and turn any book highlight into editable text — no retyping passages from paper books.
Quote notebook for iPhone
Build a second brain for the ideas that shape you
KnowledgeSaved turns fleeting highlights, big-idea quotes, and sparks of wisdom into a beautifully organized digital commonplace book — captured in seconds, found in seconds, and resurfaced when you need them.
You underline. You highlight. Then it all disappears.
The problem
Every serious reader knows the feeling: a sentence stops you cold, you underline it or fold the page corner, and you promise yourself you'll come back to it. Months later that insight is buried in a closed book on a shelf, a screenshot lost in your camera roll, or a note you can't find. The wisdom you worked to collect quietly slips through your fingers.
The KnowledgeSaved way
KnowledgeSaved is a dedicated home for the lines worth keeping — a digital commonplace book. Capture a highlight in seconds by photo, voice, or keyboard; file it with tags, author, and source; and let personalised Daily Quotes from your own collection bring your best ideas back to you. Your library grows with you instead of gathering dust.
Everything a quote notebook should do
Every feature below is in the app today — capture, organization, and rediscovery in one clutter-free notebook.
Voice-to-text
Speak insights on the go. When an idea strikes on a walk or a commute, say it and it's saved.
Fast, clutter-free typing
Classic keyboard entry that stays out of your way when you'd rather just write the line down.
Tags & smart filters
Powerful tags and smart filters mean you find the right quote in seconds, not by scrolling forever.

-
Organise and connect
Add tags, attribute the author and source, and let smart filters do the remembering. Over time your quotes stop being scraps and start being a connected commonplace book.
-
Rediscover and grow
Daily Quotes resurface lines from your own collection, so the ideas that shaped you once get the chance to shape you again — and you can see what's trending among fellow thinkers.
