Pasted File Editor
Simon Willison's Weblog·15h ago·New Tool
Simon Willison released Pasted File Editor, a browser prototype inspired by Claude's handling of large pasted text.
Instead of filling the editor with a large paste, the tool turns the content into a file attachment.
It also supports opening files directly, dragging files onto the interface, and displaying images as thumbnails. Codex desktop helped build the prototype.
