Your books, your machine.
A local ebook and comic reader for Windows. Point it at folders of books and it builds a library with cached covers — comics and ebooks side by side, in a dozen formats. No cloud, no accounts, and nothing on disk is ever moved or touched.

A proper library, built from folders you already have.
Comics and ebooks are kept as separate shelves with their own folders and reader, switched from a single toggle.
A two-phase scan lists every book immediately from folder metadata, then validates covers, page counts and hashes in the background — pausable, and resumed on next launch.
Your existing folder structure is never rearranged. Readaity catalogues where your files already live; a re-scan picks up anything you add or move.
Every book reopens where you left off, and you can drop bookmarks anywhere. The reflowable readers have Dark, Light and Sepia themes and an adjustable text size.
Finds byte-identical copies and fuzzy same-issue matches by filename, with a one-click “keep the largest” and an ignore list.
Remove a book or a whole subtree from the library and the files stay on disk. Restore them individually or all at once.
Serve your libraries to other devices at home over HTTPS behind a PIN — any browser can browse and download (with QR codes and resumable downloads). Another Readaity finds yours automatically and can import books straight across. Still no cloud.
DRM-free files you own.
Paged image view with single or dual-page spreads, keyboard and click-zone navigation, and fit-width / fit-height.
Reflowable EPUB, a full PDF viewer, and plain text with correct encoding handling. Modern Kindle AZW3 (KF8) is fully supported — including the HUFF/CDIC compression most commercial books use, and fixed-layout comics, manga and picture books which open in a page-by-page reader. Kindle and MOBI books build their chapter list from the book’s own table of contents.
Sony Reader files show in the library but need converting to EPUB (for example with Calibre) to open. Native support is planned.
Readaity opens files you own that aren’t locked with DRM. It does not, and will not, strip or circumvent protection from purchased Kindle or Adobe books — that’s out of scope on purpose.
Encrypted files are detected and shown with a clear “protected — can’t open” message rather than failing silently.
Download the latest readaity_*_x64-setup.exe from the releases page and run it. The installer is unsigned, so Windows SmartScreen will warn on first run — choose More info → Run anyway. It’s a small download because the WebView2 runtime is fetched on demand if your PC doesn’t already have it.
It’s still a 0.x release — delivered outside any store, and everything runs locally on your machine.
