The AI tool called DriveT is a document management system that helps users efficiently store, read and write documents. Users can group similar documents together in folders and the tool can index PDFs, docx, txt, website links, and YouTube videos. The AI can answer questions based on the content of the files and even helps build drafts, paragraphs, and lists. It can be used by students to store notes and ask questions, job seekers to store resumes and cover letters, professionals to search for documents based on content, and even for personal use like making lists or storing family photos.
