There's no shortage of file-sharing apps to choose from. You have Dropbox, Google Drive and OneNote for sharing just about anything on the cloud, for example, and Pushbullet is awesome for sharing files between your own devices. Simple.Savr lets you share files and text across your Wi-Fi network, and it has a simple, easy-to-use interface. You don't need to download an app or an extension to use the tool. You don't even need to register. You simply navigate to the site, upload or add text, and anything you type or upload automatically becomes available on any device connected to your Wi-Fi network. Your files are available for seven days, and there's no limit on how many files you can upload and transfer. There is a maximum file size of 25mb, however.
Again, there are plenty of other options for sharing files, but I like the simplicity and convenience of this tool. You don't have to have the app installed on any of your other devices, which is convenient if you have a Wi-Fi guest and you need to share something with them. I also like the automatic deletion feature, which means you don't really have to manage anything. So instead of using it as a file storing system, like Dropbox or Drive, you can just quickly and easily transfer stuff between other devices on your network.
There aren't any fancy features, which is kind of the idea. If you need a basic tool for transferring stuff without having to download anything, it's worth checking out at the link below.
