Frequently asked questions

What is Nyora?
Nyora is a free, open-source manga reader with 1100+ online sources, offline downloads, AI page translation and a polished reader, available across Android, Windows, macOS, Linux, iOS/iPadOS and the web.
How does Nyora relate to Kotatsu?
Nyora is an unofficial fork of Kotatsu. It reuses and extends Kotatsu and adds new platform ports, AI translation and color-correction features. It is not affiliated with the Kotatsu project. Both are licensed under the GNU GPLv3.
Where does the content come from?
Nyora does not host any manga. It connects to third-party online sources (1100+ built-in). On Android, you can also add Tachiyomi/Mihon/Keiyoushi extensions for additional sources. You are responsible for how you use it and for respecting the rights of content owners.
Is Nyora available on iOS?
Yes. Download the iOS IPA from releases and sideload it using AltStore or Sideloadly, which will re-sign the app with your Apple ID. Requires iOS/iPadOS 17+.
Is it really free? Any ads?
Yes — completely free, no ads, no tracking. Nyora is released under the GNU GPLv3, so the source is open and you can build it yourself.
Can I read offline?
Yes. Download chapters for offline reading, and open third-party CBZ archives directly from local storage.
Does my library sync across devices?
Yes. Sign in with your Google account and Nyora automatically syncs your library, favorites, categories, history, and reading progress across all devices.
Does Nyora support trackers like AniList or MyAnimeList?
Yes. Nyora integrates with AniList, MyAnimeList, Shikimori, and Kitsu (availability varies by platform). Sign in to your tracker account in Settings to sync your reading progress.
Is my library private?
You can lock the app behind a password or fingerprint, and use incognito mode to read without recording history.
Does the AI translation work offline?
Nyora supports whole-page translation. Download the ML models in Settings for an offline fallback when you have no connection.
Which reading modes are supported?
Left-to-right, right-to-left and vertical (webtoon) modes, all customizable per title, with gesture support in the reader.
A build won’t compile — what should I try first?
For Android, run ./gradlew clean and restart Android Studio; keep ksp.incremental=false if you hit KSP/caching issues. For desktop ports, ensure you have JDK 17+ on PATH.
