Concatenate Studio
This is a form-over-function tool that allows for concatenating files with a web interface.
Drag and drop files or a whole folder, and the script will output the contents combined in a single text string.
Motivation
I wanted to pass multiple files from multiple folders to an LLM, but its web interface didn't allow for that.
The "solution"
We are getting closer by the day to software on demand generated on the fly by AI. I just 'proompted' a simple page that joins the contents of folders.
Functionality
Drop folders or files anywhere on the "app", and they will get concatenated. There is a whole sidebar with a single option to append filenames. There you can also drag to reorder files (implemented poorly). Click on a file to focus the content in the output. There are also buttons to copy to clipboard or download as a file.
Recursive folder contents processing
The feature that a drop can process a whole folder and its contents (including folders inside) has been implemented in major browsers for a decade. However a lot of websites don't support it even if it makes perfect sense (like dropping a folder of photos for a gallery post on social media). This website supports it.
Conclusion
This is not very useful, but it is one of the things that exist now. You can check it out in the following link Files Concatenator or in the iframe below.
