Who it's for

  • Anyone who needs to open a contract, manual, or research paper PDF right now and ask, "What does this clause mean?"
  • Anyone who wants to try it without signing up. Just drag and drop a file to start chatting immediately with zero setup required.
  • Students quickly skimming through a few research papers for an assignment. If you only need to ask a few questions per document, the free tier is enough.

Drawbacks

  • The free limit is small. It allows 2 PDFs per day and up to 120 pages per file, so thick books or multi-paper collections must be split before uploading.
  • While it tells you which page the answer is based on, it does not cite down to the sentence level, making it weak for precise academic citations.
  • It only handles PDFs. You will need other tools for YouTube videos, web articles, or audio files, and querying multiple files in a single chat is only available on paid plans.

Getting started

  1. Open the official website and drag and drop your PDF file onto the screen. You can do this without logging in.
  2. Once the file is processed, a summary and suggested questions will appear automatically. Clicking a suggested question helps you get the hang of it.
  3. Type your question in Korean in the input box below. Example: "Summarize the penalty conditions mentioned in Chapter 3 in a table."
  4. Click the page number attached to the answer to check the original text.
  5. If you use it daily or work with long files, create an account and consider the Plus plan. Chats used without logging in disappear when you close the browser, so copy any important answers right away.
