GPTEnhancer

GPTEnhancer targets one of the most common friction points in ChatGPT: getting your own material into the conversation. Support for .txt, .js, .py, .html, .css, .json, .csv, .pdf, .png, .jpeg and .jpg files makes it useful both for developers who want help debugging or writing tests and for anyone who needs to discuss a document, a data table or a screenshot with the model.

The workflow is deliberately simple. A submit button in the ChatGPT page opens a file picker, then the extension breaks the file into manageable numbered chunks and inserts them into the chat. You can set the delay between chunks (eight seconds by default) and, on newer versions, type a custom prompt of up to about one hundred words that runs before the file content. A coloured button tells you where you are: yellow while uploading, green when the whole file has been submitted.

The extension runs locally in your browser and its listing states that it does not collect your files or data. It is a lightweight utility rather than a full chat client: it does not replace ChatGPT, add its own model, or expose an API. It simply makes the built-in chat a better place to work with files.
