Utilities we needed while reading Japanese, rebuilt as the smallest thing that does the job. No account, no database, no API, no token cost — the browser does everything, and nothing is uploaded.
| № | Tool | Runtime | Data | Offline |
|---|---|---|---|---|
| 01 | Kana ConverterHiragana to katakana and back, with half-width and full-width handling. Paste any Japanese and read the result out loud before you commit it. | Browser | None | Yes |
| 02 | Gojūon with Pitch AccentThe fifty-six cells of the kana grid, each with its modern Tokyo pitch pattern, a sample word, and the mora count that makes the contour predictable. | Browser | None | Yes |
| 03 | Vertical & Horizontal PreviewSet one sentence both ways: horizontal left-to-right and vertical top-to-bottom, with ruby over the kanji. The difference is most of the argument for reading Japanese. | Browser | None | Yes |
