FAQs

What is a second brain?

A Second Brain is a concept that refers to an external system or tool used to store, organize, and manage information, ideas, and knowledge. It acts as an extension of your mind, helping you offload cognitive tasks, remember important details, and enhance productivity. The term was popularized by Tiago Forte, a productivity expert, through his Building a Second Brain (BASB) methodology.
What is the difference between Rabrain and other second brain apps?

Rabrain is a “Retrieval Augmented Brain” - second brain app enhanced with advanced AI capabilities. Unlike traditional note-taking tools, Rabrain seamlessly integrates AI features like semantic search, automatic summarization, and content generation. By combining the organizational power of a second brain with cutting-edge AI technology, Rabrain helps you not just store knowledge, but actively engage with and learn from it in ways that weren't possible before.
What is the second brain method?

The Second Brain Method is a systematic approach to managing information and knowledge using tools and techniques to create an external “brain”. Tiago Forte's methodology is based on four key principles, summarized by the acronym CODE: Capture, Organize, Distill, Express.
Is Rabrain available for free?

Yes! Rabrain offers a generous free plan to get you started on building a second brain powered by AI. Experience the power of AI super memory without any upfront cost.
Why is it called Rabrain?

“RA” in Rabrain stands for Retrieval Augmented Generation, a key AI technology we use. Retrieval-Augmented Generation (RAG) is a framework that combines information retrieval systems with large language models (LLMs) to improve the output of AI models. RAG allows AI models to access external knowledge bases to generate more relevant and accurate responses. Thus, Rabrain is a “Retrieval Augmented Brain” - a second brain enhanced with Retrieval-Augmented Generation and large language models. It allows you to not only build a second brain, but also interact with your second brain.
