ChatExt adds the missing upload control directly to the chat page, so you can attach documents the way you would in an email client. The extension supports up to ten files in a single selection and a wide range of formats, from source code like .java and .json to plain text, .docx, and .csv. When a file is too long to fit comfortably, ChatExt automatically chunks it into manageable pieces so the conversation continues without errors. On the way out, dedicated download buttons let you grab a generated code snippet or a CSV table straight from the reply instead of copying it out line by line. PDF and Excel files are not supported at the moment, which is worth knowing before you install it for a spreadsheet-heavy workflow. Otherwise it is a lightweight, free helper aimed at people who use ChatGPT with real files every day — developers, analysts, and writers. It focuses on the mechanics of moving data in and out, and leaves the conversation itself to ChatGPT. **Pricing & Plans:** Free.

Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting. The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go. Knowt is free to use for core studying, with unlimited learn mode and free practice tests.
