AI-powered cloze reading view + spaced-repetition review mode. Stack: Obsidian Plugin API + React 18 + Ant Design 5 + esbuild + TypeScript.

Features

1. Custom markdown reading view: The "Open AI cloze reading view for current note" command renders the current note in a separate tab, where the AI automatically identifies key knowledge points and blanks them out. Click a blank to reveal/hide the answer in place (only a CSS class toggle — no full-page rebuild, no flicker). Tables, dataview, math formulas, code, mermaid, and other elements are all preserved intact.
2. Configurable provider & model: The settings panel supports OpenAI-compatible / Anthropic / Ollama (local), with Base URL, API Key, model, temperature, and max tokens; a "Test AI connection" button fires a minimal request to verify connectivity in one click.
3. Adjustable cloze density: A 0–100% slider adjusts the blank ratio in real time (top-N% ranked by AI importance).
4. Memory & auto-cloze switches: Each open reads the per-note cache (data.json) directly for the last result; the AI is only re-invoked when you click "Re-cloze with AI"; a yellow hint appears when "original note modified". Enable "auto cloze" in settings to invoke the AI automatically when opening an uncached note (long notes consume a lot of tokens; a hint is shown when this triggers).
5. Review memory mode: Flip through cards term by term, click "reveal answer", and rate Again / Hard / Good / Easy (SM-2-style spaced repetition; ease/interval/lapses/reps/due stored in data.json). On completion, Good/Easy terms can be written back to the note as under a "🎴 cloze flashcards" section (#flashcards review/flashcard, compatible with the Spaced Repetition plugin).
6. Bidirectional document navigation: When any markdown note is open, an "AI cloze" button in the view header opens its cloze reading view in one click; the "Back to note" button in the cloze view toolbar jumps back to the original note (activates the existing tab if already open).

Demo

A demo note is included at demo/demo-note.md. Open it in Obsidian and run "Open AI cloze reading view for current note" to try AI cloze generation, density adjustment, review cards, and flashcard export.
