# PDF Question Answering

HyperSkill supports question answering over PDF documents, so learners can ask questions and get answers drawn from the documents you add to a simulation.

## Enable PDF Question Answering

1. [Upload a set of documents](/hyperskill-studio-authoring/media.md) to your media library.
2. Enter edit mode in your simulation and enable PDF Question Answering under AI -> AI Chat. See [AI Chat Edit Mode](/hyperskill-studio-authoring/ai-features/ai-chat/edit-mode.md).
3. Go to Settings -> Microphone and ensure Microphone Input is enabled.
4. Go to Settings -> Documents and add documents.

## Additional notes

* All documents you list will be used for question answering.
* Question answering can work with any number of documents.
* All documents need to be processed before question answering can be performed. This occurs automatically the first time you use the feature in experience mode.
  * While a document is processing, the system will notify you it is unable to answer your question.
  * This only occurs once per document. Using the document in another or subsequent experience will not require re-processing.
