See the difference
What the same goal gets you in each
We started from the same one-line goal, "Reading a P&L statement for non-finance managers". Fenzo built a course from it. In Gemini Notebook (formerly NotebookLM), we turned on Learning Guide in a new notebook, typed the same goal, and accepted its offer to research sources on the web. No prompt tweaking.

What each tool is built for
is built for learning.
Fenzo is a learning agent. Give it a goal, or your own notes, and it builds a personal learning experience around it in seconds. Every course is taught the way its subject is taught, math like math, code like code, and holds the answer back so you do the thinking: hints first, then the answer once you have tried. You practice, get feedback that pinpoints your gaps, and watch your skills report grow.
For professionals trying to stay ahead in the AI era
Gemini Notebookis built for research.
Gemini Notebook (formerly NotebookLM) is Google's research tool for your own material, and a very good one. Add PDFs, Google Docs and Slides, web pages, YouTube videos, and audio, and it answers from those sources with inline citations. It builds study guides, flashcards, quizzes, mind maps, and interactive Learning Overviews, and turns your sources into Audio and Video Overviews. For learning, the Learning Guide chat style tutors you with open-ended questions, step by step. It teaches from what is in the notebook, and when the notebook ends, so does the structure.

Where Fenzo wins
- A full course from one line. No prompt engineering. Fenzo decides the starting point, the end goal, and the path.
- Taught the way your subject is taught. Each subject gets its own generator, with its own approach.
- Learn by doing. Every lesson makes you work through the material instead of reading about it.
- Holds the answer back. Hints first, then the answer once you have tried. Unlike typical chatbots that give you the answer, we make you work through it so you actually learn.
- See what you actually know. Feedback pinpoints your gaps, and a skills report shows your proficiency for every skill you've covered.
- Always current. Courses are refreshed as their field changes, so you never study last year's version.
- Learn in the format that fits. Structured courses, flashcards, guides, practice tests, or AI roleplays of real workplace scenarios, built for how you need to learn.

- Answers with inline citations from the documents you add
