LangSplainer

A small toolbox for language learners: sentence explainers, difficulty analysis, text splitting, and Anki workflows.

Most tools use your own API key and store it locally in localStorage. Anki tools expect Anki + AnkiConnect running on your machine.

Sentence Explainers

Multi-angle explanation and JSON output: simplified versions, translations, segmented breakdown, and recommendations.

Chinese‑first breakdown with pinyin, inline grammar tags, and compact HTML formatting.

Select text inside a passage to get an immediate, focused breakdown of the selected snippet.
