Feature
Sources
Add documents, websites, and videos to give your AI assistant context about any topic.
What Are Sources?
Sources are the files and content that power your notebook. When you add a source, Onsomble reads it, breaks it into chunks, and creates searchable embeddings. This lets the AI answer questions using your actual content.
Think of sources as your notebook’s memory. The more relevant sources you add, the smarter your AI conversations become.
Supported Types
| Type | Formats | Best For |
|---|---|---|
| Research papers, reports, ebooks | ||
| Word | .docx | Documents, proposals, drafts |
| Text | .txt, .md | Plain text, markdown notes |
| Web Pages | Any URL | Articles, documentation, blogs |
| YouTube | Video URLs | Tutorials, lectures, interviews |
| Audio | .mp3, .wav, .m4a | Podcasts, recordings, meetings |
| Video | .mp4, .webm | Presentations, screen recordings |
Files can be up to 50MB each. You can upload up to 10 files at once.
How Processing Works
When you add a source, Onsomble processes it in the background:
- Content extraction — Pulls text from PDFs, web pages, and transcripts
- Chunking — Breaks content into smaller pieces for better retrieval
- Embedding generation — Creates vector representations for semantic search
- Knowledge graph — Optionally extracts entities and relationships
You’ll see a status indicator on each source:
| Status | Meaning |
|---|---|
| Processing | Source is being analyzed |
| Ready | Processing complete, available for chat |
| Failed | Something went wrong (click to retry) |
Most sources process in under a minute. Large PDFs or long videos may take longer.
Using Sources in Chat
Your sources power the AI chat. When you ask a question, Onsomble:
- Searches your sources for relevant chunks
- Includes them as context for the AI
- Generates an answer based on your content
Select specific sources before chatting to focus the AI on particular documents. Click sources to toggle them on/off for the current conversation.
Knowledge Graphs
Sources can be visualized as knowledge graphs — interactive maps showing entities and their relationships.
Click Knowledge Graph in the Sources panel footer to:
- See entities extracted from your sources
- Explore connections between concepts
- Discover patterns across documents

Best Practices
Quality over quantity — A few well-chosen sources beat dozens of loosely related ones.
Use descriptive names — Rename sources so you can find them later.
Organize early — Create folders before your notebook gets crowded.
Check processing — Wait for the green checkmark before chatting about a source.
Mix source types — Combine documents, articles, and videos for richer context.
