Things are going slow, but it is a passion project so it's ok :)
A few people have bought a licence and it seems most people who try the app are very happy with it so I'm happy too.
The app is entirely in Java, with javaFX for the UI and Lucene for the search engine. To read and render PDFs I use PDFium.
I'm still working on my PDF search engine for desktop: https://www.docgoblin.com/
I'm implementing a bookmark utility right now and hope to add support multiple E-books format in the near future.
I am still working on Docgoblin (https://docgoblin.com) a Pdf search engine software based on Lucene, pdfium and JavaFX. The app is super fast and users are happy with it. I'm in the process of adding plain text files support and making the website look nicer.
I'm currently working on a PDF search engine that will index and then search through several thousand pdfs. As a tabletop role-player and former researcher, I've always wanted a simple tool to do this, and I hope I won't be the only one to benefit from it. This is my first project of this scale and I hope to be able to show it here soon.
On the technical side, it's a desktop application coded entirely in java with a javaFX interface. No AI or online data uploads, just the Lucene search engine and PDFium for PDF rendering.
