Use Perplexity as a research instrument: shape answerable questions, choose the current search mode, grade citations, run deeper research, and maintain a reusable Project.
You already know what Perplexity is and you have asked it questions. This course is about the next thing: using it the way a working researcher uses a good instrument. You will learn to shape a question it can actually answer, to choose the search depth and the model behind the answer on purpose, to read its citations as a mix to be graded rather than a badge of trust, to commission Deep Research for the heavy multi-source jobs, and to keep a Space that stops you re-explaining yourself every time.
The through-line is one habit that gets deeper as the tool gets more powerful: judge what comes back before you rely on it.
