jidoujisho vs jsonfmt.dev

jidoujisho brings video playback, reading, dictionary lookup and flashcard creation into an Android language-learning app. It handles local media, YouTube videos, Jellyfin streams and direct URLs, with word lookup by tapping or dragging across subtitles and paragraphs. Readers can open offline books in the embedded ッツ Ebook Reader or read manga processed with Mokuro. For study cards, users can edit fields and export the current image and audio to AnkiDroid. Dictionary support covers Yomichan, Migaku and ABBYY Lingvo DSL formats; dictionary data is not bundled, and Yomichan structured-content dictionaries are unsupported. Listed services include ChatGPT, Bing image search, Forvo, JapanesePod101 audio search, and example sentences from Massif, Tatoeba and ImmersionKit. WebSocket support allows use with texthookers. Japanese and English are officially supported; other languages depend on dictionary format and search support. jidoujisho is free and open source under GPL-3.0. It requires Android 7.0 or later and AnkiDroid. External subtitles include SRT, ASS and SSA, but not image-based PGS.

jsonfmt.dev is a web-based JSON formatter, beautifier and validator, with an HTTPS API for JSON processing. The formatter offers 2-space, 4-space or tab indentation, optional key sorting and depth control. It validates JSON against RFC 8259 and reports line and column errors. Other tools can repair common malformed JSON, compare two documents and convert formats including YAML, CSV, XML, TypeScript, SQL, GraphQL and Protobuf. The toolkit also includes a JWT decoder, JSON Schema validator, JSONPath evaluator and JSONL tools. The maker says the core browser tool handles JSON locally without sending its contents to the server, and continues to work offline after loading; it can also be installed as a Progressive Web App. API options include anonymous access limited to 10 requests per minute, a free API key tier with 100 requests per minute and 1,000 per month, and Pro API at $9, paid once for 1,000 requests per minute and 50,000 per month. Share links encode JSON in the URL fragment, and anyone with the link can access its contents.
