Seeneva is a free and open-source smart comic book reader developed by RustyCoder for Android devices. This app is specifically designed to make reading digital comics on mobile devices easier and more enjoyable. It supports different comic book archives and image formats, and allows you to view ComicRack metadata. Seeneva also supports Left-to-Right (LTR) and Right-to-Left (RTL) read directions.

One of the standout features of Seeneva is its smart speech balloon zooming. The built-in Machine Learning model is trained to detect speech balloons on pages, making it easy for you to zoom in and navigate through them with a touch of a finger. The app also has Optical Character Recognition (OCR) and Text-To-Speech (TTS) functionalities. OCR enables you to extract text from speech balloons, while TTS allows you to use Seeneva as an audio comic book reader.

It's worth noting that Seeneva is a libre application under the GPLv3 or later license, meaning it is free of ads and personal data collection. However, no comic books are included in the app, and the OCR and TTS features are currently only available in English. For more information and known issues, check out the app repository on GitHub.
