Are you experiencing this: you’ve saved 26 practical articles in WeChat Favorites but never opened them again; your computer has 10+ scattered files in a folder called “Study Materials”; you want to find a theory you read half a year ago but only remember a few keywords. And when the amount of information you receive each day exceeds your brain’s processing limit, 90% of valuable knowledge is forgotten within 72 hours.\
Now, by using the Infini-AI Model Service Platform API + Cherry Studio to build a personal knowledge base, you can turn WeChat articles that have been gathering dust in Favorites and fragmented course content into structured knowledge for precise retrieval.\\
### 1. Building a Personal Knowledge Base

As the “thinking center” of the knowledge base, the Infini-AI Model Service Platform provides model versions such as the full-powered DeepSeek R1, offering stable API services,**Currently, after registration, it can be used for free with no barrier.**It supports mainstream embedding models such as bge and jina to build a knowledge base,**and the platform is also continuously updating stable, latest, and most powerful open-source model services**covering multiple modalities such as images, video, and voice.
#### 2. Cherry Studio: Build a knowledge base with no code
Cherry Studio is an easy-to-use AI tool. Compared with RAG knowledge base development, which requires a 1–2 month deployment cycle, this tool’s advantage is that it supports**zero-code operation,**and can import Markdown/PDF/web pages and other formats with one click. A 40 MB file can be parsed in 1 minute. In addition, you can also add local computer folders, article URLs from WeChat Favorites, and course notes.\\
