Google renamed NotebookLM to Gemini Notebook in July 2026, shipped Expert Intelligence for licensed books, and kept expanding Studio outputs — audio, slides, data tables, and leaked App tiles. On August 30, 2026, TestingCatalog spotted the next piece: Interactive Reports — "An interactive report with embedded Studio content."
Nothing is public yet. The leak still matters: Google is pushing notebooks from chat answers to composite research workspaces — the same direction as Google Antigravity interactive artifacts.
TL;DR
| Item | Detail |
|---|---|
| Feature | Interactive Reports in Studio → Create Report flow |
| Description string | Interactive report with embedded Studio content |
| Status (Aug 31, 2026) | UI/copy in testing; not live for users |
| Source | TestingCatalog teardown, Aug 30, 2026 |
| Companion leaks | App, Canvas, Lit Review tiles (July–Aug 2026) |
| Shipped nearby | Expert Intelligence (books RAG), multi-format export |
What TestingCatalog saw
According to the Aug 30 report:
- Studio panel notice: "New: you can now create interactive reports" with a button into the existing Create Report customization flow.
- New preset Interactive marked New — embed Studio outputs inside the report.
- Overview preset also references interactive summaries incorporating Studio content.
- Example prompt shape: structured market research (e.g., functional beverage landscape) — closer to workspace than static PDF.
Earlier leaks (July 29 – Aug 3) exposed an App tile generating dashboards, study aids, or lightweight games from notebook sources — inactive, but sharing the same Studio panel.

Contrast with Expert Intelligence:
| Capability | Expert Intelligence (shipped) | Interactive Reports (leaked) |
|---|---|---|
| Primary input | Licensed Play Books + your files | Notebook sources + Studio outputs |
| Output | Grounded Q&A with citations | Multi-artifact report |
| Interactivity | Chat + citations | Embedded Studio widgets |
| Status | Live (Aug 28, 2026) | Testing only |
What builders should watch
- Licensing: Expert Intelligence gates book content by purchase; Interactive Reports must clarify embed rights for generated Apps and third-party sources.
- Sandbox boundaries: Notebooks already run code in per-notebook sandboxes — embedded apps inherit that trust model (compare secure MCP patterns).
- GEO/SEO: Prompt-published reports may become indexable collateral — structure headings and citations for AI overviews (GEO guide).
- Competitive bar: OpenAI pushes ChatGPT Work deliverables; Google answers with notebook-native publishing.
Honest limits of a leak post
- Strings in client builds ≠ shipping dates — Google may rename, merge into Apps, or cancel.
- No API docs — automation hooks unknown.
- Enterprise Workspace rollout order typically lags consumer Gemini tiers.
