what it is
Nightspar is a vocabulary app with a built-in MCP server. Connect Claude, ChatGPT, Cursor, VS Code or Claude Code once, and the assistant you already chat with can save words into your library mid-conversation, a single word or several at once, and read back what you have saved. Ask what a word in a sentence means, then say "add it to Nightspar". The phrase is saved with the context from that conversation and gets a full AI-built flashcard: meanings, translation, pronunciation, examples and audio. Reviews are scheduled with FSRS, the algorithm Anki uses. Sign-in happens in a browser window, with no keys or tokens to paste. 34 languages, free during the beta.
