A student’s account describes speaking with ChatGPT Dots while asking it to summarize lecture slides, research additional sources and prepare a study guide and practice questions. Results arrived through the conversation and a notification after background work. The author values NotebookLM’s grounding in uploaded materials but says generating study artifacts during voice discussion required switching to another interface. Separate Work or Codex tasks still consume usage allowances, and Dots requires an eligible paid plan. This is an individual workflow report, not a controlled comparison of learning outcomes or accuracy.
