Reedle - AI PDF & EPUB Reader

Reading PDFs, EPUBs, videos, or web articles — only to forget them within days?

Sound familiar?
- Highlight a PDF and never look at those notes again
- Struggle through foreign-language articles word by word
- Watch a video tutorial but lose the key ideas by morning
- Saved dozens of web clips you've never opened since
