How it works
Everything you need. Nothing you don’t.
Many study tools bury the basics under menus and settings. Cozy-Reader keeps just four, side by side with your PDF.
02Ask
Highlight it. Ask about it.
Select a passage and ask the AI assistant to explain it, summarize it, or give an example. Every answer cites its pages, so you can check the source.
03Take notes
Take notes without switching apps.
Notes open right beside your PDF. Quote a passage and it links back to its page. Add images, headings, and lists.
04Study
Make flashcards in one click.
Highlight text and click the flashcard button, or let the assistant draft cards for you. Short study sessions bring back the cards you missed.
Also inside
The small things are here too.
Quiet tools that stay out of the way until you want them.
Search the whole book
Press the shortcut, type a word, and jump to the page it’s on.
Light or dark
Paper by day, a warm dark page at night.
Bookmarks
Keep your place on any page.
Contents and thumbnails
Move by chapter, or by the look of a page.
Five highlighters
Color-code the passages you quote.

Clean reflowed text, or the PDF as printed.

Flashcards that repeat what you miss

From our readers
Made for people who’d rather just read.
Students, researchers, and curious readers use Cozy-Reader to get through hard PDFs without fighting their tools.
I’m usually reading a few papers at once. When I get an answer I want to use in my notes, I can click through to the exact page and check what the authors actually said.
Maya P.
Ecology PhD candidate
I mostly read after work, when I’m already tired. I like that I can open a book and get right back to it without a bunch of stuff on the screen.
Claire B.
Lifelong learner
When a paragraph in an API doc isn’t clicking, I ask what it means in plain English and keep reading. That usually saves me a detour through a bunch of browser tabs.
Priya S.
Software engineer
I used to copy bits of my casebook into a separate flashcard app. Now I highlight the part I want and make the card right there, while I still remember why I marked it.
Elena V.
Law student
For boards, I keep my notes next to the chapter I’m studying. If a quote stops making sense a week later, I can click it and read the surrounding paragraph again.
Alex N.
Medical student
I kept getting the same few chem cards wrong, so they kept coming back. By exam week, I had a pretty good idea of what still needed work.
Sam C.
Chemistry undergraduate
When I half remember a quote while writing an essay, I can describe it and jump back to the page to check the wording.
Nina G.
History undergraduate
