Filesystem Access lets you describe complex tasks and let the agent handle them end-to-end. Combine browser automation with local file operations — research on the web, then save reports directly to your folder.

​
Why Filesystem Access?

Without Filesystem Access, the agent can only interact with browser tabs. With Filesystem Access enabled, it gains full access to a folder on your machine:

Read files

Access documents, data files, and more from your selected folder

Write files

Save reports, spreadsheets, markdown, HTML, and other outputs

Run commands

Execute shell commands within the folder
The real power: do both browser automation AND file operations in a single task. Describe what you want, step away, and come back to finished work.

​
