mazemaze

Read foreign articles without a dictionary. Swaps part of page text into your target language. 100% on-device AI.

[Read Webpages with Mixed Languages] Ever tried reading a foreign-language article, only to get fatigued by looking up unfamiliar words every few seconds? Translating the entire page removes the learning opportunity, while reading purely in the foreign language can be overwhelming. mazemaze offers a refreshing approach to encounter foreign languages while reading everyday web content. By replacing a customizable portion (10–80%) of sentences on any webpage into your target language, surrounding sentences provide context clues. You can read naturally while encountering foreign expressions throughout your regular web browsing. [Key Features] - Selection Mixing: Mix the whole page or target highlighted paragraphs and sentences. - Auto Mode: Automatically mixes newly opened pages using your saved preferences. - Granularity Control: Choose between Phrase, Sentence, or Passage mixing units. - Learning Levels: Adjust between Easy (shorter sentences), Standard, and Challenge (longer sentences). - Reading Log & Benchmarks: Tracks words read, active streak days, and quiz accuracy, estimating CEFR, TOEIC, and Eiken benchmark levels. - Original-Text Quiz & TTS Audio: Hover over translated sentences for a 3-choice quiz (with confetti on correct answers). Includes TTS pronunciation playback. - One-Click Toggle: Click any translated sentence to toggle back to the original text, or restore the entire page with "Undo". - Custom Appearance: Choose Highlight (colored), Underline only, or Blend in (plain text). - Restricted Page Guidance: Shows helpful guidance and a link to practice on the official site when opened on internal or store pages. - Modern UI: Intuitive card layout with smooth light and dark mode support. [Privacy First: On-Device AI & Flexible API Integration] By default, translation and quiz generation run 100% locally on-device using Chrome's built-in Translator API with zero external transmission. Free, no API keys required, and no account registration needed. * For supported desktop Chrome environments where the built-in AI is unavailable, you can optionally connect your own Gemini or OpenAI API key (BYOK). When BYOK is enabled, only text selected for translation is sent directly to Google/OpenAI endpoints under your own API account and pricing terms. Keys and settings are stored strictly in your local browser storage and are never sent to developer servers. [Supported Languages] Japanese, English, Korean, Traditional Chinese, and Simplified Chinese (bidirectional mixing; page language detected automatically). [Requirements] Requires Chrome 138 or later on desktop (when using built-in translation), or a Gemini/OpenAI API key on supported desktop Chrome environments. On first use of built-in translation, Chrome downloads the on-device model once locally.
