## What is 水杉词典 MetaSeq?

MetaSeq (水杉词典) is an AI dictionary that explains words across languages, including the specialist terms ordinary dictionaries leave out. Type a word in English, Japanese, Latin or any other language, or a term from medicine, law or programming, and MetaSeq explains it in the language you read best.

WHAT YOU CAN DO
- Type in any language: no need to pick a language first. German, Arabic, Latin or a mix are recognized automatically.
- Look up specialist terms: medicine, law, programming, finance, engineering, music and more, with the accepted translation in that field and how the term is used.
- Explanations in your language: choose Chinese, English or Japanese for definitions. Deep explanations cover context, usage and commonly confused words.
- Multi-language comparison: see what the same word is called in Chinese, English, Japanese, German and other languages at a glance.
- Ask follow-up questions under any entry, or open 问 AI (Ask AI) for a free-form conversation.
- Photo lookup and voice input: photograph a page, a menu or a street sign and tap the word you want, or just say it.
- Remember it: saved words go into your word book and come back for review on a spaced-repetition schedule, a few minutes a day. Export the word book to CSV or Anki.
- Sync: sign in with the same account on iPhone, iPad and the web, and your word book, review progress, history and settings stay in sync.
- On iPad, the list sits on the left and the entry on the right, handy while reading. 11 themes to choose from.

The app's interface is in Simplified Chinese; definitions can be explained in Chinese, English or Japanese.

FREE AND METASEQ PRO
The free plan includes 10 AI lookups and follow-up questions per day (photo lookups count toward them), reset at midnight in your time zone, and 5 themes. The word book, review and offline packs have no daily limit.
MetaSeq Pro adds unlimited AI lookups and follow-up questions, deep explanations, all 11 themes and unlimited photo lookups. Choose monthly, yearly (with a 7-day free trial) or lifetime (one-time purchase). Prices are shown in the App Store for your region.
- Payment is charged to your Apple Account at confirmation of purchase.
- Monthly and yearly plans are auto-renewing subscriptions. They renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and the renewal is charged within 24 hours before the period ends.
- Manage or cancel subscriptions in Settings > Apple Account > Subscriptions. Deleting your MetaSeq account does not cancel a subscription.
- Any unused portion of a free trial is forfeited when you purchase a subscription.
