Unified Space
Your notes live alongside your books.
No more switching between a reader and a notes app. No more copy-pasting quotes. No more losing context. Your thinking happens right beside what inspired it.
Highlight a passage and watch it flow into your notes — with the source, the page, the context preserved. Add thoughts without leaving the page. The reading and the thinking happen in the same breath.

User selects text, highlight glows, flows to notes panel with automatic citation, user adds comment

Block-based notes
Drag blocks to reorganize. Reference other notes. Build connections between ideas.

Synced everywhere
Your notes follow you across devices. Start on your laptop, continue on your phone.
Progress Made Achievable
Big books, made manageable.
Large books can feel overwhelming. Yaumy breaks them into natural chunks — pieces you can finish in a single sitting. Ten minutes. Fifteen minutes. Whatever time you have.
Every chunk you complete moves the progress bar. You see exactly where you are and where you're going. The finish line isn't some distant abstraction — it's visible, approaching, achievable.
Progress & Chunks Demo
Reading a chunk, chunk completes with celebration, progress bar updates, streak counter increments
Visual progress tracking
See exactly how far you've come. Watch the bar fill. Feel the momentum build.
Reading streaks
Build consistency with daily streaks. Don't break the chain. Show up every day.
Completion predictions
Know when you'll finish at your current pace. Turn distant goals into concrete timelines.
Remember what you read. Forever.
Tools that turn fleeting exposure into lasting knowledge.
Vocabulary builder
Encounter a word you don't know? One click saves it with definition, pronunciation, and examples. Build vocabulary naturally as you read.
Flashcards with spaced repetition
Turn highlights into flashcards. The system tests you at scientifically optimal intervals — just before you'd forget.
Knowledge that compounds
Every word you learn, every concept you master, becomes part of you. This isn't cramming — it's true learning.
Vocabulary & Flashcards Demo
Word tapped, definition appears, saved to vocabulary list, flashcard review session, mastery indicators
Beautiful Design
A creative space for your thinking.
Your notes don't have to live in white boxes with black text. They can have personality. Patterns — dots, grids, waves, hexagons. Gradient backgrounds that shift like sunset skies. Typography that matches your mood.
And if you want something truly unique? Upload a photo — a painting you love, a place that inspires you — and let AI generate a theme that matches. Your workspace transforms in seconds.
Theme Customization Demo
Theme gallery, selecting different themes, transitions between styles, AI image upload generating custom theme
Patterns & gradients
Dots, grids, waves, hexagons. Sunset oranges, soft purples, ocean blues. Make it yours.
AI-generated themes
Upload an image. Watch AI create a matching theme. 5 credits free monthly, 50 with Pro.
Notebook-level customization
Every notebook can have its own feel. Philosophy notes feel different than business notes.
Built for trust. Designed for privacy.
Your notes contain your most personal thoughts. We protect them with encryption that means even we can't read what you write.
End-to-end encryption
Notes are encrypted on your device before syncing. We never see your content — that's the point.
Zero-knowledge architecture
We don't track what you read. We don't analyze your notes. Your library is yours alone.
You control your keys
Your encryption keys stay with you. A secure recovery key ensures you never lose access.
Device management
See every device connected to your account. Revoke access instantly if something looks wrong.
Full data portability
Export everything anytime in standard formats. Your data is yours — take it wherever you go.
No ads. No tracking. Ever.
We make money from subscriptions, not surveillance. Your attention and data aren't products.
“Privacy isn't a feature we added. It's a principle we built everything around. Your ideas deserve protection that's as permanent as your thoughts.”
Everything. No catch.
Most of what you need is free. Pro unlocks more space and more power.
