Kairon — Free Android ebook reader with spoiler-safe AI Q&A and Read Aloud
About Kairon
Kairon is a free ebook reader for Android phones, tablets and compatible Amazon Fire tablets. Import your own EPUB, PDF, TXT, CBZ and audiobook files and read offline, with no account required. Its standout feature is Spoiler Lock: connect a compatible AI provider and ask questions about the book you are reading, while the app limits the AI to the part you have already reached, so you can recap characters and plot without spoilers. Kairon also includes Read Aloud text-to-speech, in-reader translation, and BookSky, an optional social tab built on Bluesky where readers share what they are reading.

What do DR4, DR3 and the model difference mean?
- DR4:
- Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
- DR3:
- The previous model, shown in the Ahrefs app until 1 December 2026.
- Model difference:
- DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
