Tomoshi Japanese Dictionary

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 an FSRS 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 · One-tap export to Anki: card backs carry full definitions, furigana on examples and a pitch-accent curve; open the file in AnkiMobile via the Files app, and re-exporting updates the same notes · Export and import the whole wordbook, or back it up daily to your own iCloud Drive · Sign in and your wordbook and review progress sync between your phone and desktop, merging changes from each device instead of overwriting them ■ AI explanations · Paste a whole sentence for a grammar breakdown with furigana; every word in the reading is tappable · 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 ■ Reading · Public-domain classics from Aozora Bunko, graded by difficulty, with a furigana toggle — tap any word to look it up ■ Audio · Entries, example sentences and whole sentences can be read aloud with cloud-synthesised voices ■ Privacy · No account needed for anything; sign in with an email code (no password) only if you want the wordbook to sync across devices — no name or phone number collected · Lookup history stays on your device — I cannot see it; the wordbook, review progress and reading position stay local too (with your own iCloud backup) until you sign in, and deleting your account removes the cloud copy · 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, which I cover myself for now; if a growing user base pushes server and AI costs beyond what I can carry, they may become paid to balance them. 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-assisted and cross-checked by multiple models · Pronunciation and pitch accent are human-verified · Full attribution in the app under Me → Settings → Open-source licences ■ Other platforms Desktop versions for Windows and macOS are at tomoshi.app, with a select-to-look-up browser extension.
