🤔 When to Consider Upgrading?
Upgrading your Miva plan unlocks more power and value, especially when you need to explore topics more deeply, find yourself reading more frequently, or want to boost your overall efficiency.
- Explore Deeper: When you want to go beyond the basics and truly grasp a book's essence, Miva Pro gives you a higher reading quota (60 mKPU) and more interactions (30) within each reading cycle, so you can follow your train of thought without interruption.
- Active Usage: When you need to understand multiple books quickly, frequently reference material for work or study, or prepare for a presentation, Miva Pro keeps you productive without having to wait for your quota to reset.
- Boost Efficiency: Miva Pro deliver higher-quality reading, more precise knowledge from books, and more powerful analytical tools to significantly enhance your learning and research.
Miva Pro is likely the best fit for you if:

- You're looking for more detailed introductions and deeper insights into books.
- You use Miva for more than 30 minutes each day.

💡 The mKPU System Explained
mKPU, or mini Knowledge Processing Unit, is the metric BookAI uses to measure the amount of knowledge processed by its AI services. Think of it as a way to calculate "work" rather than just words.
- 1 mKPU = The capacity to process 100 full-width characters (e.g., Chinese, Japanese) or 300 half-width characters (e.g., English, German).
- For reference: 15 mKPU is what Miva uses, on average, to help you understand the core essence of a short article or a single book chapter.

Miva's Knowledge Map technology is highly efficient. It condenses content so you can quickly grasp an author's key ideas from a minimal amount of text, dramatically improving your reading efficiency. Different Miva versions offer different depths: Miva Lite is perfect for discovering new books, Miva Pro is designed for reading books in-depth.
