Is NotebookLM the same as Gemini Notebook?

Yes. Google renamed NotebookLM to Gemini Notebook in July 2026. The product is the same source-grounded research tool; only the name changed. Check Google's current product page to confirm the latest name and features.

Can ChatGPT do what NotebookLM does?

ChatGPT can accept uploaded documents and answer questions about them, but it does not ground every answer in specific passages the way Gemini Notebook does. For a workflow where accuracy and traceability to specific sources matter, Gemini Notebook is the more rigorous tool for that part of the work.

Does NotebookLM remember my work between sessions?

Gemini Notebook keeps your sources and the conversation within a notebook. It does not have a general memory of your work across notebooks or sessions the way some other tools do. Save conclusions and next steps outside the notebook if you need them to travel.

Can I share a NotebookLM notebook with a colleague?

Notebook sharing is available on some plans. Check Google's current Gemini Notebook documentation for the plan and sharing options that apply to your account.

Which is better for a student: NotebookLM or ChatGPT?

They are better for different things. Gemini Notebook is better for studying a specific set of materials — it keeps answers grounded in the text and shows where each answer came from. ChatGPT is more useful for open-ended writing, explanation, and tasks not tied to a defined document set. Many students use both.

NotebookLM vs ChatGPT: Sources, Study, and Ongoing Work

NotebookLM (now Gemini Notebook) grounds answers in the documents you upload. ChatGPT is a broad conversational assistant. Here is how to choose between them and how to keep your work when you use both.

NotebookLM — renamed Gemini Notebook by Google in July 2026 — answers questions strictly from the documents and sources you give it. ChatGPT draws on a broad general training and can take on almost any conversational task without you supplying files first. They are complementary tools for different moments in a research or project workflow.

Using both is common. The problem is that checked sources from Gemini Notebook and decisions made in ChatGPT live in separate places. Tools like fenbs keep references, progress, and decisions in one record that any connected AI can read, so moving between tools does not mean starting the explanation from scratch.

At a glance

Gemini Notebook (NotebookLM) vs ChatGPT: key differences
Area	Gemini Notebook (NotebookLM)	ChatGPT
What it draws on	Only the sources you upload	Broad general training plus uploaded files
Source grounding	Answers cite the specific document and passage	Answers draw on training; citations need manual verification
Best for	Research, literature review, studying a document set	Open-ended writing, analysis, coding, planning
Memory	No persistent memory across sessions; tied to your source set	Optional memory feature; check current availability by plan
Collaboration	Share a notebook with others (check current plan limits)	Team plan for shared workspaces; separate accounts otherwise
fenbs	Keeps references, checked facts, and project decisions outside either app so both tools read the same record	Keeps projects, tasks, Decisions and rules portable across tools

Source grounding: the core difference

Gemini Notebook is built around sources. You upload PDFs, Google Docs, web URLs, or other materials, and every answer it gives is traceable to a specific passage in those documents. If the answer is not in your sources, it says so rather than generating something plausible that may be wrong.

That makes it unusually reliable for research and studying. You can ask it to summarize a set of papers, identify contradictions between two reports, or explain a concept using only the terminology in your uploaded text. The answer points back to the source, which makes it easy to verify.

ChatGPT answers from its general training. That is far more flexible — you can ask about topics without uploading anything — but it also means the answer can contain confident-sounding errors. When accuracy matters, you still need to check the sources yourself, whereas Gemini Notebook makes that checking part of its interface.

When to use Gemini Notebook

Gemini Notebook is the right starting point when you have a defined set of materials to work through. A student analyzing court opinions, a lawyer reviewing a stack of contracts, a researcher working through a body of literature — all benefit from an assistant that stays within those materials and shows its work.

It is also good for deep listening. Gemini Notebook can generate audio overviews of a source set — a kind of AI-narrated summary useful for review while commuting or working away from a screen. Check Google's current feature list to see what is available on your plan.

One practical limit: Gemini Notebook does not hold memory between sessions beyond the notebook itself. If you want to record what a research session concluded, where you left off, and what questions remain, that needs to happen somewhere else. That is a good fit for a shared record in fenbs — or for links and references listed in your project alongside the notebook.

How fenbs helps

Keep checked references and research progress in one place

After a Gemini Notebook session, save the key conclusions, the checked references, and where the research stands in a fenbs project. Note which sources confirmed the main points and what questions remain open. The next session — in any AI app — starts from those conclusions rather than re-reading the materials.

When to use ChatGPT

ChatGPT is more versatile for open-ended tasks: drafting, planning, coding, thinking through a problem without a predefined document set, or working through a task where the question is not yet well defined. Its broad training makes it useful for tasks Gemini Notebook is not designed for.

ChatGPT is also useful for taking the conclusions from a research session and doing something with them — drafting a memo, writing a section, or working out how to explain a finding to a non-technical audience. The research in Gemini Notebook and the writing in ChatGPT are a natural pair.

ChatGPT's memory features, where available, let it retain some personal preferences or context between sessions. Check OpenAI's documentation for what memory does and does not carry between conversations, and which plans include it.

Using both together

Many researchers and students use Gemini Notebook for the sourced, document-grounded phase and ChatGPT for writing, planning, and open conversation. The challenge is that checked facts and conclusions from one session need to travel into the next without being retyped or lost.

How to do this with fenbs

Set up a fenbs project for the research or study work. Use it to record what each tool session concluded — not the raw transcript, but the useful findings and next steps.

Create a free account at fenbs and add the project — a research topic, a writing assignment, or a work investigation.
After a Gemini Notebook session, add a task for the key finding or conclusion. Note which sources confirmed it and any caveats.
Record standing rules in Decisions and rules: which sources are authoritative, which claims still need checking, any limits on what AI may conclude without human review.
Connect AI apps at Integrations. The next ChatGPT or Claude session reads the conclusions from the Gemini Notebook work before drafting.
