What it does
JLPT Mastery is an adaptive JLPT preparation platform that combines a structured N5–N1 curriculum with performance-driven learning. It tracks your progress, identifies weak points, and automatically reinforces them through practice and review. Failed questions are resurfaced, and AI explanations help you understand mistakes. With dedicated exam and practice modes, along with a full progress dashboard, it replaces scattered resources with a single, focused system.
Adaptive JLPT preparation for all 5 levels. Confusion tracking, spaced repetition, and AI explanations across 8,700+ vocabulary words and 489 grammar patterns.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
