Everything yomeru.ai knows about Japanese,callable as MCP tools.
Grammar Lab
Full Japanese sentence breakdown. Every grammar point named — verb conjugations, particles, sentence-ending forms, honorifics, conditionals. Markdown explanation with vocab callouts and JLPT levels. Backed by a curated grammar resource set, JMDict, and a native-tuned LLM.
Grammar Lab Fast
The same Grammar Lab analysis, run on smaller AI models for speed. Trades a touch of depth for sub-second responses. Default this when latency matters and you want a quick gloss; reach for grammar_lab when the sentence deserves the full pass.
Word Lab
Complete dictionary cards: readings, JLPT level, frequency rank, every sense with parts of speech and tags. JMDict (~200k entries) + JMnedict + Tatoeba. AI fallback for words outside JMDict.
Example Sentences
1–5 example sentences per word. Each row tagged tatoeba, jmdict, or ai_generated. The fifth is freshly LLM-generated to round out short sets, with model + version metadata.
