What It Is

3MinTop is an AI reading assistant and online ebook reading platform built around the idea of “understanding the core content of a book or chapter in 3 minutes a day.” It combines an ebook reader, AI summaries, full-text translation, content Q&A, mind maps, and reading progress tracking, with the goal of lowering the barrier to reading and helping users build a consistent reading habit.

Core Features

Based on the information on the site, 3MinTop focuses on AI-powered summaries and structured understanding. Users can select a book and get a 3-minute summary of the entire book or an individual chapter. When they encounter complex concepts, the AI can explain them in plain language. The system can also generate mind maps to help users understand the relationships between chapters. It also supports full-text translation, content Q&A, cloud sync, goal management, and progress tracking, making it suitable for turning books into more digestible learning materials. In terms of models, the pricing page mentions Gemini 2.5 Flash, Deepseek R1, GPT-5 Mini, and Deepseek V4 Flash, and it also supports custom model APIs.

Pricing and Free Allowance

The free plan includes 100,000 credits, 100MB of storage, basic models, an ebook reader, cloud sync, and access to shared summaries. The Starter annual plan has a regular price of $199, discounted to $99.50/year with a promo code, and includes 5 million credits/month and 2GB of storage. The Plus annual plan has a regular price of $399, discounted to $199.50/year, and includes 15 million credits/month and 5GB of storage. Paid plans include the full feature set, more advanced models, member summary sharing, 16 custom model APIs, and priority chat/email support.

Pros and Cons

The main advantages are its focused product scenario and full workflow coverage, from importing and reading books to summarizing, translating, asking questions, and tracking review progress. The free allowance is clearly stated, and the discounted annual pricing is not too high a barrier. The Chinese-language introduction is also fairly complete. The limitations are also clear: the site does not provide a detailed list of supported formats such as EPUB/PDF, although EPUB/PDF are mentioned in the title; it does not disclose how uploaded books and Q&A data are stored, deleted, or whether they are used for training; and the user testimonials feel somewhat marketing-driven, with limited third-party validation. AI summaries also should not be treated as a complete replacement for deep reading.

Who It’s For and Access from China

3MinTop is suitable for students, professionals, entrepreneurs, content creators, and anyone who wants to expand their knowledge in short bursts of time. It is especially useful for quick overviews, pre-reading, and review. Access from mainland China and supported payment methods are not specified in the scraped content, so they should be considered unknown. If access or payment is limited, users can consider pairing domestic AI tools such as Kimi, Doubao, or Tongyi Qianwen with an ebook reader, or using alternatives such as Blinkist, Shortform, or Readwise Reader.
