ReaderBro now delivers a smoother PDF experience with smarter AI help, faster performance, improved note popups, and more.
Why ReaderBro is a must-have for MacBook users (especially students and readers):
Reading a 150+ page book in a difficult language can be overwhelming — especially when you’re constantly switching between apps just to look up meanings.
That’s where ReaderBro.com changes everything.
Just select any word, sentence, or even a full question — and ReaderBro’s built-in AI will:
• Instantly translate or explain it in simple language
• Let you save the meaning inside the app and directly in the PDF
• Next time you hover over the same word, it shows the saved meaning automatically (no need to ask again)
• When you open another PDF, it auto-highlights all your previously saved words — with meanings shown in context
Bonus: Stuck on an assignment or a math problem? Just select the question — ReaderBro will solve and explain it right inside the app.
All these powerful features — in one single app.
Try it once — especially if you’re a student or language learner.
