Tool: Pasted File Editor (https://tools.simonwillison.net/pasted-file-editor)

    I really like how you can paste a large volume of text into claude.ai (https://claude.ail) (or the Claude desktop/mobile apps) and it will detect it as a large paste and turn it into a file attachment instead.

I decided to have Codex desktop build me a version of that (https://gist.github.com/simonw/74c79119b487a5acce18b4dcc26b9f79) as a prototype.

You can also open files directly - including images which will be shown as thumbnails - or drag files onto the texture.
