Pasted File Editor
Tool: Pasted File Editor I really like how you can paste a large volume of text into claude.ai (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 as a prototype. You can also open files directly - including images which will be shown as thumbnails - or drag files onto the textarea.
