About Libar

Libar is a modern PDF reading platform built for readers, students, and anyone who works with documents. Upload your PDFs and transform them into interactive, annotated, AI-enhanced reading experiences - all from your browser.

What you can do

• Annotate freely - highlight text in multiple colors, draw shapes, save bookmarks, and collect favorite quotes.
• Build components - place interactive widgets like videos, images, text blocks, memory games, and matching exercises directly on pages.
• AI Component Builder - describe what you need and let AI generate custom interactive components for you.
• AI Helper - ask questions about the page you're reading. Summarize, explain, or translate content instantly.
• Search - full-text search across entire PDFs (subscription required).
• Cloud sync - keep your library, annotations, and components in sync across devices (subscription required).
• Export - download standalone HTML files with all your annotations and components embedded (subscription required).
