About Japanese Lookup — Tra cứu tiếng Nhật
Japanese Lookup is a Chrome extension for reading the web, studying online, or working with Japanese content. A DangLong Digital product; connect to danglongdigital.com to get an API key.
How to use
• Highlight (mouseup), select text, or highlight/select + hold Alt — depending on your settings
• Each lookup or AI request: up to 300 characters of the text you select
• The popup shows Vietnamese/English meanings, furigana, usage, examples, and practical notes (some items require Pro)
Features
• Look up vocabulary, kanji, and grammar from the catalog on danglongdigital.com
• Details tab: meanings, usage, examples — furigana on kanji only; phrases not in the catalog may show a word list to choose from
• Kanji tab: KanjiVG stroke order (when the term contains kanji)
• AI tab: explanations when you tap the button (API key from the key management page on danglongdigital.com)
• Correctly selects words with furigana/ruby on web pages (readings are not mixed into the middle of words)
• Long selections: AI returns a shorter summary (translation + nuance) to save quota
• No Google sign-in required inside the extension
AI quota (transparent)
• Free: up to 5 AI uses/day and 30 AI uses/month per account (not multiplied by the number of API keys)
• Lookup Pro on the website: higher AI quota
• Dictionary & furigana are unlimited and do not use quota — only AI explanations count
• Quota is deducted only when AI generates a new response; viewing a cached result does not count
• Daily quota resets at 0:00 Vietnam time (UTC+7); monthly quota follows your account/plan cycle and does not roll over
Privacy & legal
• Only the text you select is sent to our servers — we do not read the full page
• API key is stored on your device (chrome.storage.local); UI settings may sync via Chrome Sync
