Understanding the Knowledge Base
Learn how to leverage your personal knowledge base to get AI responses that are grounded in your own learning materials. Upload documents, organize files, and supercharge your AI assistant.
What is the Knowledge Base?
The Knowledge Base is your personal library of learning materials that Nullset's AI uses to provide accurate, contextual responses. When you upload documents, the AI can reference them to give you answers that are specific to your coursework, textbooks, or any material you're studying.
Upload
Add your PDFs, documents, and more
Search
AI retrieves relevant content
Answer
Get grounded, accurate responses
How RAG (Retrieval-Augmented Generation) Works
RAG is the technology that powers the Knowledge Base. Here's how it works in simple terms:
Document Processing
When you upload a file, we break it into smaller chunks and create mathematical representations (embeddings) that capture the meaning.
Semantic Search
When you ask a question, we find the most relevant chunks by comparing the meaning of your question to the stored content.
Augmented Response
The AI receives your question along with the relevant context from your documents, generating an accurate answer grounded in your materials.
Pro Tip
The better organized and more comprehensive your uploaded materials, the better the AI can assist you. Consider uploading lecture notes, textbook chapters, and study guides together.
Uploading Files
Supported File Types
How to Upload
- Navigate to your Space and click the "Upload" button in the sidebar or chat interface.
- Drag and drop your files or click to browse. You can upload multiple files at once.
- Wait for processing to complete. The AI will automatically index your content.
YouTube Links
You can also paste YouTube video links! We'll automatically extract the transcript and add it to your knowledge base. Great for lecture recordings!
File Limits
Maximum file size: 50MB per file.Free users can upload up to X files. Pro users get unlimited uploads.
Managing Your Knowledge Base
Best Practices
- • Upload complete chapters or sections
- • Include lecture slides and notes together
- • Use descriptive file names
- • Organize by topic in separate Spaces
- • Upload problem sets with solutions
- • Uploading image-only PDFs (no text)
- • Mixing unrelated subjects in one Space
- • Uploading corrupted or password-protected files
- • Using very short documents (< 1 page)
- • Duplicate uploads of the same file
