Google has launched Notebooks in Gemini, a new organizational layer that groups related chats, files, and project context into a single persistent workspace. Unlike standard Gemini conversations that exist in isolation, Notebooks let users create project-scoped containers — similar in spirit to Claude's Projects feature — where AI context, uploaded documents, and conversation history persist and accumulate over time. The feature integrates with Google Workspace, allowing users to attach Google Docs, Sheets, Drive files, and Gmail threads directly to a Notebook. Gemini can then be queried across all attached materials in a unified way, making it useful for long-running research, client projects, or any work that spans multiple sessions and document types. Notebooks debuted at #2 on Product Hunt with 181 upvotes on launch day. This positions Gemini more directly against Claude's Projects and ChatGPT's memory-augmented workspaces. For Google Workspace users in particular, the tight Drive and Docs integration gives Notebooks a material advantage — it's the only AI workspace with native access to the full Google productivity stack. Enterprise buyers who've already committed to Workspace will find the feature immediately useful without any additional setup.

Perplexity Comet Browser

A Chromium browser with an AI agent baked into every tab

Comet is a standalone Chromium-based browser built by Perplexity that ships with a persistent AI sidebar agent. The agent can fill forms, summarize pages, conduct research, and execute multi-step web tasks without switching context. Early access is rolling out via waitlist to existing Perplexity users.

The Google Workspace integration is the story here — native Drive, Docs, and Gmail context inside an AI workspace is something Claude Projects and ChatGPT can't match out of the box. For teams already deep in Google's ecosystem, this is a no-brainer upgrade to their AI workflow.

Claude Projects and Notion AI already do this better in many respects. Google has a history of launching polished features and then abandoning them — Stadia, Inbox by Gmail — so long-term commitment is a real concern. The feature is also locked behind Gemini Advanced for power usage.

The direct competitor here is Arc Browser plus any AI extension, or just Chrome plus the Perplexity extension that already exists — and Perplexity already ships that extension. The specific scenario where this collapses is enterprise adoption: IT departments don't swap default browsers for waitlist products, and consumers don't either without a compelling reason beyond 'the sidebar is better.' The prediction: Google ships Gemini natively into Chrome at a depth Perplexity can't match within 18 months, and the browser angle becomes indefensible. For this to earn a ship, Comet needs a capability that is literally impossible to replicate in an extension — and form-filling and summarization are not that.

Persistent, project-scoped AI workspaces are the natural evolution of how knowledge workers will interact with AI — not ephemeral chats but living project brains. Google pushing Notebooks mainstream normalizes this interaction model and accelerates adoption across the massive Workspace install base.

The thesis here is falsifiable: the browser is the last surface layer a model provider can own before cloud platforms commoditize the query layer, and whoever owns ambient web interaction owns the monetization stack that replaces the search ad. The dependency that has to hold is that users adopt a second browser for AI tasks — a behavior that has actually happened before with Arc, Brave, and Opera, so it's not implausible. The second-order effect nobody is talking about: if Comet's agent can observe full browsing context across sessions, Perplexity builds a behavioral dataset that no API-layer competitor can replicate, which is the real moat. The trend is browser-as-OS-layer, and Perplexity is early — not on-time, early — which means the execution risk is high but the position is genuinely differentiated.

For creative projects spanning multiple briefs, reference files, and iteration rounds, having a Notebook that holds all of it in one AI-queryable space is a real quality-of-life improvement. Especially useful for agencies running multiple client projects simultaneously in Google Docs.

The buyer here is unclear in a way that should worry everyone: consumers don't pay for browsers, and enterprise won't deploy an unapproved Chromium fork from a company best known for a search sidebar. The pricing architecture is almost certainly 'bundled into Perplexity Pro,' which means the browser is a retention mechanic, not a revenue line — that's fine until you realize the cost of maintaining a browser fork is not trivial and the ROI has to be measured in churn reduction, not new ARR. The moat question is the real problem: Chromium is open, the AI agent layer is replicable, and the switching cost for a browser is extremely high to create but fragile once created. This survives if Perplexity gets acquired by a platform player who needs an AI browser story; as a standalone business decision, the unit economics don't pencil.

The job-to-be-done is specific: execute multi-step web tasks without juggling tabs, extensions, and copy-paste loops — and that is a real job that knowledge workers hire for daily. The onboarding question is the one I can't answer from waitlist access, but the make-or-break moment is whether a user can complete a real task in the first five minutes without reading docs, because agentic products that require prompt engineering upfront die in onboarding. The completeness problem is that this requires switching your entire browser, which is a massive ask — Perplexity would have shipped a stronger product by nailing the extension first and using that install base as the migration funnel into Comet rather than leading with the browser. The specific product opinion I'd give them credit for: making the agent persistent and context-aware across the session, not just per-page, is the right call and meaningfully different from extension-based competitors.
