The Aosr plugin provides an advanced spaced repetition system for Obsidian users, allowing efficient and customizable flashcard-based learning. With features such as rich text support, a dedicated review window, and minute-level interval scheduling, it offers precision and flexibility for knowledge retention. Aosr supports various card formats, including single-line, multi-line, cloze deletions, and range cards, with deck functionality that allows users to define custom rules for organizing flashcards.

The Note Synchronizer plugin bridges Obsidian and Anki, enabling seamless synchronization between notes and flashcards. It supports importing Anki note types as templates, ensuring a 1:1 correspondence between notes, decks, and tags in both platforms. Users can choose between Markdown and HTML modes for syncing content, depending on their preferences for rendering. The plugin mirrors the folder structure in Obsidian to decks in Anki, creating new decks automatically if needed.
