Gemini Notebook Interactive Reports: An Unreleased Studio Feature Explained

Google appears to be testing a new Interactive Reports capability for Gemini Notebook, the product formerly known as NotebookLM. The feature was reportedly spotted by TestingCatalog on August 30, 2026, with interface text describing “an interactive report with embedded Studio content.” It was not publicly available in the reporting reviewed for this article, and Google has not provided a launch date. 3

That makes Interactive Reports a reported in-development feature—not a confirmed product release. Its likely importance is easier to understand in the context of Gemini Notebook’s existing Studio panel, which already turns uploaded sources into reports, mind maps, data tables, slide decks, infographics, and other artifacts. 29

What Interactive Reports is expected to do

The proposed feature would bring several of those artifacts together in one navigable report instead of requiring users to generate and manage each output separately. A report could combine written analysis with supporting Studio content, such as:

• Mind maps for organizing themes or relationships
• Charts and other visualizations
• Data tables for structured comparisons
• Additional source-based Studio artifacts

The reported description is deliberately broad: “an interactive report with embedded Studio content.” Reports also indicate that the feature could support user-research reports and complex visualizations. Those use cases and the exact embedded objects remain based on leak reporting rather than official product documentation. 37

How the reported Studio workflow would work

The reported entry point is the existing Studio panel. Google’s help documentation describes Studio as the place where outputs based on a notebook’s sources are generated, including notes, mind maps, reports, and other formats. 2

According to the reports, a new notice in Studio would lead users into the existing Create Report customization flow. That flow would reportedly add two presets:

• Interactive: intended to combine narrative with embedded Studio content.
• Overview: apparently intended to produce a more conventional synthesized report.

Users would also reportedly be able to provide a free-form prompt, add custom instructions, and select an output language. The precise controls—such as whether users can choose individual charts or mind maps manually—have not been officially documented. 357

An example prompt

A suitable test prompt, based on the reported free-form workflow, might look like this:

Create a formal 2026 functional-beverage-market competitive review for executive leadership. Analyze market size and growth, consumer segments, leading competitors, pricing and distribution, product claims, risks, and strategic opportunities. Include a competitor comparison data table, a market-growth chart, a category mind map, and source citations. Use concise, board-ready English.

This is an illustrative prompt, not a confirmed Google template. Its purpose is to show the proposed distinction between generating a standard report and asking Gemini Notebook to assemble a complete research deliverable with supporting visual and structured elements.

What Gemini Notebook already supports

Interactive Reports would extend capabilities that are already present in Gemini Notebook rather than introduce source-based document generation from scratch.

The official help documentation says users can create custom reports or choose formats such as FAQs, study guides, briefing documents, and AI-suggested report types. Reports can be exported to Google Docs, while reports containing data tables can export those tables to separate Google Sheets tabs. Data tables can also be customized with a prompt and chosen language, with citations placed in a separate tab. 2

Google’s June update also described a broader set of generated outputs, including PDF reports with charts and tables, budget spreadsheets, student worksheets, chart and data-visualization exports in PNG and SVG, and documents in PDF, DOCX, Markdown, and plain text. 8 TechCrunch additionally reported support for structured data such as CSV and JSON, Microsoft Excel, and PowerPoint, while noting that availability was initially tied to certain Google AI Ultra and Workspace access plans. 20

Those format claims should not be treated as one definitive support matrix for every Gemini Notebook user. The clearest Notebook-specific documentation confirms Google Docs export for reports and Google Sheets export for data tables. 2 The broader list is supported by Google’s update and third-party reporting, but availability and supported formats can vary by product surface and account tier. 820

Why the feature matters

The proposed change is less about adding another report template and more about connecting Gemini Notebook’s existing artifacts. Today, a user might generate a report, then separately create a mind map, chart, or data table. Interactive Reports could make those outputs part of one source-grounded document.

That direction fits Gemini Notebook’s broader product evolution. Google renamed NotebookLM to Gemini Notebook on July 16, 2026, describing it as the same standalone product with broader Google ecosystem integration and a secure cloud computer. 14 Google’s product materials also position Gemini Notebook as a way to transform uploaded documents and other sources into reports, mind maps, slide decks, audio and video overviews, flashcards, infographics, and more. 9

The result is a shift in emphasis: Gemini Notebook is not limited to answering questions about a collection of files. It is increasingly positioned as a workspace for turning source material into usable research and business outputs. Interactive Reports would be a logical connective layer between those outputs.

What remains unconfirmed

Several details in the original reports should be treated cautiously:

• Release timing: No public launch date has been announced. 3
• Availability: The supplied evidence does not establish whether Interactive Reports will be free, limited to Google AI Ultra, restricted to Workspace accounts, or released more broadly.
• Final interface: The Interactive and Overview presets were reported, but their final behavior and artifact-selection controls are unknown. 37
• Underlying model and execution features: The supplied sources do not independently verify claims about a specific Gemini 3.5 foundation or the exact ability of a secure cloud computer to execute code against uploaded sources.
• Audience figures: Google’s rebranding announcement says that more than 30 million people and over 600,000 organizations were using NotebookLM at the time of the announcement. Those are Google’s stated figures, not independently verified measurements. 14

Bottom line

If Google releases it as reported, Interactive Reports could turn Gemini Notebook from a collection of source-grounded generators into a more unified research-production workspace. The reported concept combines a free-form prompt with narrative, charts, mind maps, data tables, and other Studio content in one interactive document.

For now, however, the right verdict is provisional: the feature appears to be in testing, it is not publicly available in the supplied reporting, and its final capabilities, access model, and launch date remain unknown. 37
