About omakase

Credits. Built by Sebastián R. Vansteenkiste via DeepSeek V4 Flash @ FREEBUFF (affiliate link) — an independent, from-scratch reimplementation inspired by tangorin.com (developed by Gregory Bober, now owned by Archie Preston). omakase is not affiliated with Tangorin, EDRDG, or any other source or contributor.

Dictionary data. Built from open datasets, each with its own license and attribution:

JMdict, KANJIDIC2, kradfile-u, radkfile — © James William Breen & The Electronic Dictionary Research and Development Group (EDRDG), CC BY-SA 4.0 (licence statement); kradfile-u further © Jim Rose (KanjiCafe.com).
KanjiVG stroke-order diagrams — © Ulrich Apel, CC BY-SA 3.0 (kanjivg.tagaini.net).
JmdictFurigana ruby segmentation — © Doublevil, MIT; data derived from JMdict (CC BY-SA 4.0).
jmdict-simplified JSON conversion of the EDRDG files — © scriptin, MIT packages; data CC BY-SA 4.0.
Tatoeba example sentences — © Tatoeba contributors, CC BY 2.0 FR (some CC0). Test fixtures only — the shipped dictionary carries no sentences, so the app never shows one.
Catalan query index (not dictionary content: it lets a Catalan word be searched in Spanish, which is the only language the dictionary glosses it in) — © the Apertium project, apertium-spa-cat, GPL-2.0. Generated from that data, so the table ships under GPL-2.0 while the app stays MIT; the verbatim licence is in LICENSES/GPL-2.0.txt.

Software. better-sqlite3 (MIT) · @sqlite.org/sqlite-wasm (Apache-2.0; SQLite itself is public domain) · dev tooling: TypeScript (Apache-2.0), tsx (MIT), puppeteer-core (Apache-2.0). Full license texts ship with the app in LICENSE.md (plus the vendored GPL-2.0 text); per-component notices live in NOTICE.md.

Disclaimers. Dictionary data is provided without any warranty as to its accuracy or suitability (EDRDG licence); it may contain errors, and users assume all liability for its use. Stroke diagrams come from the bundled KanjiVG set and are cached locally. The app works 100% offline — nothing you look up ever leaves this device.

Works with no connection

omakase runs entirely on this device: the dictionary lives in your browser's storage, and nothing you look up ever leaves it.

Experimental language

This language is experimental and its dictionary coverage is partial — some entries fall back to English. English is the recommended language for the complete experience.
