In this new video, I walk through 7 real tasks that Claude Cowork's file access unlocks and that weren't possible before:
- Summarize a whole folder of PDFs into one research dossier
- Edit and reorganize your files in place, not just get told what to do
- Rewrite a book chapter with tracked changes
- Clean up a messy project folder in minutes
- Trace 18 years of personal files to see how things changed over time
- Work right inside your own tools, like Obsidian
- Synthesize across completely separate folders
If you have a Second Brain, this is the feature that makes your file system the center of the work again.
