Free, open-source Android reader for light novels, webnovels, web novels, and ranobe from 25+ sources — now with built-in machine translation in the reader and NoveLA-style TTS spoken-word highlighting. Read any novel in your language, or listen hands-free while the words light up.
Translate the exact chapter you're reading — no copy/paste, no leaving the reader.
- One-tap translation from the reader's Aa toggle or the chapter bottom sheet
- 4 providers: Google Gemini API (BYO AI-Studio key) · any OpenAI-compatible API (OpenAI, Groq, OpenRouter, DeepSeek, Mistral…) · Google Translate (Enhanced) · Google Translate (Simple) (zero-config, no key)
- 4 reading modes: Original only · Translated only · Parallel (original first) · Parallel (translation first)
- Editable translation prompt, regex cleanup of footnotes/URLs, source auto-detect + target language, and a model picker that accepts any model name (e.g.
gemini-3.7-flash) - NoveLA-parity engine — paragraphs are translated in configurable batches (“Paragraphs per request”, default 60) with a tunable max output-token cap, and multiple API keys per provider (one per line) are load-balanced and rotated automatically on rate limits (429/5xx)
- Offline cache (SQLite) — translated chapters are stored locally, so revisits never re-translate
Translation backends — four supported, with automatic retry on rate limits (429/5xx):
| Backend | Cost | API key |
|---|---|---|
| Google Translate (Enhanced) | Free (translate-html endpoint) | Not required (community key; optional personal keys) |
| Google Translate (Simple) | Free | Not required |
| Google Gemini API | Free tier | Required (one or more) |
| OpenAI-compatible API | Varies | Required (one or more) |
NoveLA-style listening: the text-to-speech engine highlights each word as it's read aloud, in sync with playback — with a manual hex color picker (e.g. #FF6B6B soft red, #4CAF50 green) or presets, plus speed and pitch sliders.
