Store description excerpt
Tomoshi is a Japanese-English dictionary built for producing Japanese, not just decoding it. It helps you say it and write it right. ■ Lookup · Type Japanese, kana, romaji or English; candidates appear as you type · 210,000+ entries, with English-to-Japanese reverse lookup for when you know the word in English and need the Japanese · Results follow the spelling you searched, so 「明」 does not surface entries that look unrelated ■ Definitions you can use · English definitions and part-of-speech tags · Reading, pitch accent and a pitch-accent curve · Conjugation table at a glance · Example sentences with furigana that follows the entry you are reading ■ Help with producing Japanese · Transitive / intransitive pairs: 「開く／開ける」-style verb pairs shown side by side with matching example sentences · Near-synonym notes: how similar words differ and which one fits which situation · Kanji spelling notes: what each spelling of the same word is used for ■ Remember it · Save any entry to the wordbook and review it on a spaced-repetition schedule · Listen-only drills: hear the word without seeing it and train your ear to react · A small red dot appears when words are due; after a session you see your review streak · Export and import the whole wordbook, or back it up daily to your own iCloud Drive ■ AI explanations · Paste a whole sentence for a grammar breakdown with furigana; every word in the reading is tappable and leads back to the dictionary · Expressions the dictionary does not cover are handed to AI, so you are never stuck at "no results" · When the model is not sure, it says so instead of inventing a plausible-sounding explanation ■ Audio · Entries, example sentences and whole sentences can be read aloud with cloud-synthesised voices ■ Privacy · No account; no name, email or phone number collected · Lookup history, wordbook and review progress stay on your phone (and in your own iCloud backup) — I cannot see them · No ads, no third-party analytics · Crash reports are sent by default, can be turned off in Settings, and never include what you searched · Full policy: tomoshi.app/privacy/en ■ Connectivity · The first launch downloads the dictionary data once; after that, core lookup works offline · AI explanations and speech are the two features that need a connection ■ Free Looking words up is free forever: the complete dictionary data, offline lookup and the error-reporting feature are free now and will stay free. Cloud features such as AI explanations and cloud speech are free to use today, within a daily quota. Every call to them has a real server cost behind it, so they will move to paid to cover that cost. Put simply: the dictionary is free; the cloud services that cost money to run will eventually be paid. I would rather state the rule from day one. ■ Where the data comes from · Entries are based on JMdict / EDRDG and other open dictionary projects; example sentences partly from Tatoeba · Verb pairs, nuance notes and reverse lookup are AI-as
