Frequently asked questions

Gemini Notebook Toolkit is a Chrome extension that saves content from 10+ platforms (ChatGPT, Claude, Gemini, Perplexity, YouTube, Reddit, LinkedIn, X, Substack, arXiv, GitHub, and more) directly to Google Gemini Notebook with one click. Free tier; Pro at $5/month (or $4.17/mo ($50/year)).

Yes. Gemini Notebook Toolkit is the leading companion Chrome extension for Gemini Notebook (formerly NotebookLM). It adds one-click capture from AI chats, YouTube, and the web, a searchable library of everything you save, and export tools — all working seamlessly with your Gemini Notebook notebooks.

Gemini Notebook Toolkit is the most comprehensive Gemini Notebook Chrome extension: 10+ source platforms, free tier, 16-language UI, active weekly development. It addresses Gemini Notebook's primary friction point — source capture — across the broadest surface available.

Not for personal accounts. As of October 2026 Google documents no consumer Gemini Notebook API; only the Gemini Notebook Enterprise API, in Preview (v1alpha), for Google Cloud customers. If you want an AI agent to search your research, Notebook Toolkit runs a remote MCP server over the library you save with it.

Both are third-party Gemini Notebook extensions with free plans. Toolkit focuses on capturing AI chats and web pages into a searchable, exportable library with an MCP server; Kortex focuses on in-notebook tools such as merge, podcast RSS and automations. Lifetime: Toolkit $149, Kortex $200.

There are three options. Free: core one-click capture from major AI platforms, YouTube, and web pages — no credit card. Pro: $5/month, or $4.17/mo ($50/year), for unlimited capture, workspaces, and prompts. Lifetime: $149 one-time for all Pro features with 250 AI actions a month (fair use).

Yes. As of October 2026, Gemini Notebook Toolkit Lifetime is a $149 one-time payment for every Pro feature, plus future Pro features, for the lifetime of the product. It includes 250 AI actions a month under fair use, resetting monthly, with a 14-day refund. Polar handles payment as merchant of record.

Yes. NotebookLM, now called Gemini Notebook, is free with a Google account. Since 2 September 2026 chat and Studio usage is measured by compute (prompt complexity, chat length, number of sources and features used) and refreshes every 5 hours up to a weekly limit, instead of a fixed number of daily questions. The standard tier supports up to 50 sources per notebook. Paid Google AI plans raise the limits.

Yes. Gemini Notebook is free for anyone with an eligible Google account. As of October 2026 Google also offers students a free year of a paid plan: eligible US college students get Google AI Pro, which has 4x standard notebook limits, and students elsewhere get Google AI Plus. Redeem by 31 December 2026.

Yes. Gemini Notebook Toolkit uses an optional host-permissions model — you grant access to specific sites only, not all sites. Source content is routed to your Gemini Notebook account; minimal metadata is retained for the workflow. No third-party data sharing. Full policy at notebooktoolkit.com/privacy.

Google's stated policy: Gemini Notebook does not use your uploaded content to train its general AI models. Your sources are not visible to other users and are not used for advertising. Workspace tier offers stronger data controls for organizational use.

For Google Workspace business accounts, Gemini Notebook offers strong data controls including data residency and admin audit. For personal accounts, the privacy policy is solid but check your IT policy before uploading proprietary content. HIPAA workloads require specific Workspace BAA contracts.

As of October 2026, Gemini Notebook meters usage by compute rather than fixed daily counts. Since 2 September 2026 your allowance refreshes every 5 hours, up to a weekly cap. Heavy outputs such as Video Overviews cost most, so near your limit you can queue them to generate automatically after the next reset.

As of October 2026, every plan uses the same compute-based limits, scaled by a multiplier. Free accounts get the standard limit, Google AI Plus gets 2x, Google AI Pro 4x, and Google AI Ultra 5x or 20x the Pro limit depending on the subscription. Features rolling out first, such as Voice Chat, usually reach Ultra first.

Gemini Notebook (formerly NotebookLM) allows up to 50 sources per notebook on the standard tier, and each source can be up to 500K words or 200 MB. Since 2 September 2026 chat and Studio usage is measured by compute (prompt complexity, chat length, number of sources and features used) and refreshes every 5 hours up to a weekly limit. Paid Google plans raise these limits.

Google currently documents 50 sources per notebook on the standard service, with 100 notebooks per account. Paid Google plans raise the ceiling, but the exact limits vary by plan and region.

As of October 2026, Gemini Notebook runs on Google's Gemini 3.5 family. Reports say the upgrade began rolling out in June 2026, first to Google AI Ultra and then to Google AI Pro on the web, replacing Gemini 3. Google does not let you pick the model, and it can differ by plan and feature.

As of October 2026, Gemini Notebook works only in Google-supported countries and for users above the age of consent in their country. The message usually means your region, account age verification, or a school, work or Family Link account policy blocks it. A VPN breaks Google terms and does not fix account-level blocks.

Yes. In July 2026 Google renamed NotebookLM (now Gemini Notebook) as part of consolidating its AI tools under the Gemini brand. It is the same product — your existing notebooks, sources, and shared links keep working, and Google auto-redirects old notebooklm.google.com links. Gemini Notebook Toolkit works exactly the same under either name.

Keep your own copy of every source outside Gemini Notebook (formerly NotebookLM). Save the original files and links, copy important notebooks, and export source text to Markdown or other files so you can rebuild a notebook if a source is removed or stops loading.

Since 23 October 2026, Gemini Notebook is a Connected App in Gemini. Type @Gemini Notebook in a chat to create notebooks, add sources, save notes or ask about an existing notebook. It works in the Gemini web app and mobile app, not the Mac app yet, and is off by default in the European Economic Area.
