Adding Sources
Four ways to bring content into your notebook.
You can add sources to your notebook in four ways: upload files, add URLs, paste text directly, or import from other notebooks.
Upload Files
The most common way to add sources.
- Click the + button in the Sources panel
- Select the File tab
- Drag files onto the drop zone, or click to browse
- Click Upload to add them
You can upload multiple files at once. Each file shows a progress bar while uploading.
Supported File Types
| Type | Extensions |
|---|---|
| Documents | .pdf, .docx, .txt, .md |
| Audio | .mp3, .wav, .m4a |
| Video | .mp4, .webm |
Maximum file size is 50MB. You can upload up to 10 files at once.
Add a URL
Import content from any website.
- Click the + button in the Sources panel
- Select the URL tab
- Paste the web address
- Click Add to import it
Onsomble extracts the main content from the page. It works with most websites, blogs, and documentation sites.
YouTube Videos
For YouTube videos, just paste the video URL. Onsomble automatically:
- Detects it’s a YouTube link
- Extracts the video transcript
- Processes it like any other source
YouTube transcripts work best when the video has captions. Auto-generated captions are supported but may have some inaccuracies.
Add Text Directly
Create a source from text you type or paste.
- Click the + button in the Sources panel
- Select the Text tab
- Give it a title
- Type or paste your content
- Click Add to save it
When to Use Text Sources
- Meeting notes — Paste notes from a meeting you attended
- Quick references — Add a snippet you want to reference later
- Manual transcripts — Add content that isn’t available as a file
- Summaries — Write a summary of something you want the AI to know
Import from Other Notebooks
Reuse sources across notebooks without re-uploading.
- Click the + button in the Sources panel
- Select the From Notebooks tab
- Browse your other notebooks
- Select sources to import
- Click Import to copy them
This creates copies of the sources. Changes to the original won’t affect your imports, and vice versa.
When to Import
- Related projects — Share research across multiple notebooks
- Templates — Keep standard reference materials in a “template” notebook
- Collaboration — Import sources a teammate has already processed
After Adding
Once you add a source, Onsomble processes it automatically:
- Extraction — Content is pulled from the file or URL
- Chunking — Text is broken into smaller pieces
- Embedding — Vector representations are created for search
- Ready — A green checkmark shows it’s available for chat
Most sources are ready within a minute. You can add more sources while others are processing.
