"Upload to OpenAI Vector Store" is a Chrome extension developed by rekih, falling under the Browsers category with a subcategory of Add-ons & Tools. This free tool allows users to instantly upload the active tab's content in PDF format to OpenAI's Vector Store for use with OpenAI's Assistant API.

To set up the extension, users need to input their OpenAI API Key and Vector Store ID in the designated fields, which are securely stored in the browser's local storage. Once configured, users can simply navigate to any web page with a PDF file, click on the extension icon, and the upload process will automatically begin, using the URL as the file name (".pdf" might be appended).

In case of accidental uploads, users can easily manage their content by visiting OpenAI's console for removal.
