Pasted File Editor
— Create and manage a text editor with automatic file attachment capabilities. Paste files or text content of 1,000 characters or more to attach them below the editor, while keeping the editor text unchanged. View attached files as previews or in full, and remove files as needed using drag-and-drop, file selection, or clipboard paste functionality.
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 texture.
