Inlinea - A Linux-first, annotation-focused PDF editor built with GTK4

Inlinea is an open-source, annotation-focused PDF editor focused on clean UX and native Linux experience. Features include: • Browser-style tabs • Inline and area highlights • Add-text-anywhere annotations • Dual-page reading mode • Lazy rendering for large PDFs • Embedded annotation saving Built with Python, GTK4 and Libadwaita.

Hey folks! Maker of Inlinea here. I recently switched to Linux for my daily workflow and realized something surprising: I couldn’t find a PDF editor that felt clean and fast for annotation. Most tools were either: powerful but heavy and cluttered or lightweight but missing basic annotation workflows So I started building one for myself. Inlinea is a Linux-first, annotation-focused PDF editor built with Python, GTK4 and Libadwaita, focused on a clean and native desktop experience. It's still early, but already usable. If you’re on Linux and work with PDFs regularly, I’d really appreciate feedback: bugs, ideas, feature requests, anything. Thanks for checking it out 🤝
