'Undo send' for files: a project to recall shared files before they're opened
Most of us have shared a file and instantly wished we could take it back. This Reddit post describes a side project that lets you cancel a file share after sending — before the other person opens it. Think of it like the 'undo send' button in email, but for files.
Once you share a file link, there's usually no way to stop the recipient from opening it. This project tries to solve that by letting the sender revoke access to a file within a short window after sending, similar to how some email apps let you cancel a message seconds after hitting send.
The idea targets situations where you pick the wrong file, share something sensitive by accident, or simply change your mind. The post appears to be a founder sharing an early-stage tool and asking if others have felt the same frustration. This is a general productivity utility and is not directly related to AI agent development or cost reduction.
