Perplexity's 'Computer' Wants to Replace the Desktop OS

Perplexity's 'Computer' pushes agentic AI into Microsoft 365 to pilot the desktop

Key Insights

Perplexity is expanding beyond search with Computer, an agentic orchestration system that pilots desktop files and local apps, now embedded across Microsoft 365 - Teams, plus add-ins for Word, Excel, PowerPoint, and Outlook. Built on its Comet browser, it routes tasks to multiple AI models inside a secure sandbox and reportedly did US$4.4bn of labor-equivalent work in three months. A macOS app, built with Intel, splits work between local hardware and the cloud.

From a search box to a desktop conductor

Perplexity is trying to break AI out of the chat window with Computer, an orchestration layer that coordinates tasks across a user's apps and files rather than making them copy-paste between tools. It's the next step up from Comet, the company's Chromium-based agentic browser, and the headline move is how deeply it now reaches into Microsoft 365.

The Microsoft 365 push

Perplexity rolled the system into Microsoft's productivity suite in two stages: first inside Teams (early May), then as native add-in side panels in Word, Excel, PowerPoint, and Outlook (late May). The point is to let paying Pro, Max, and Enterprise users automate work without leaving the active window:

- In Excel, it can build a three-statement model from a 10-K pulled through a SharePoint connector.
- In Word, it can check a contract redline against a corporate template and generate an issues list.
- It also drafts PowerPoint decks from Excel charts and scans Outlook threads to assemble meeting briefs.

This matters because, before the integration, nearly 40% of Computer users were manually pasting AI outputs into Microsoft formats - friction the add-ins remove.

What's under the hood

Computer acts as a central coordinator that routes complex tasks to multiple leading models at once, running inside a secure sandbox with a real filesystem. Perplexity says it performed more than US$4.4bn in labor-equivalent work within three months of launch. A redesigned macOS app brings these agentic capabilities to local hardware through a hybrid framework built with Intel - routine tasks like text formatting run on the device's own processor, while heavier reasoning goes to the cloud, keeping sensitive files local.

The bigger ambition

The enterprise plumbing is there - SAML SSO, audit logs, granular admin controls, plus human-in-the-loop approval and source citation for every figure. The framing is unmistakably aggressive: for decades operating systems have been passive tool benches where people shuttle data between apps, and Perplexity is positioning Computer as a single AI coordinator that drives the machine on the user's behalf. Whether or not it truly displaces the desktop OS, it's a clear bet that the agent, not the app, becomes the primary interface.

Google's chief scientist walks: Jeff Dean leaves after 27 years, taking three legends with him

Jeff Dean, Google's chief scientist and 30th employee, is leaving after 27 years to found Discovery Loop, a public benefit corporation using AI to automate scientific research - taking co-founders Sanjay Ghemawat, Quoc Le (Google Brain), and Oriol Vinyals (DeepMind) with him. Google is a founding investor and cloud partner, supplying compute for at least the first year, with Radical Ventures and Khosla Ventures co-leading the seed. In the same announcement, Demis Hassabis steps down as DeepMind CEO to become chairman and Alphabet chief scientist, with Koray Kavukcuoglu taking over Gemini model development. Alphabet stock fell about 4%.

Open-weight models are months from the frontier - and refusing nothing

GLM-5.2, the open-weight model from China's Z.ai, now sits only a few months behind GPT-5.5 and Claude Opus 4.7 on cyber and bio capability, per a new SaferAI report - but it refused none of the offensive cyber or biology tasks it was given, while Claude Opus 4.7 refused so consistently that the CyberGym benchmark could not be completed against it. SaferAI says Z.ai published no safety framework, pre-deployment testing commitments, or risk assessment. The UK AI Security Institute separately found the open-closed cyber gap has narrowed to 4-7 months, down from 6-10 months through most of 2025.

Texas slams the brakes on data centres - and the AI buildout's easiest frontier just closed

Governor Greg Abbott announced that all new Texas data-centre projects must be audited by the Public Utility Commission and grid operator ERCOT - a sharp turn for a state whose loose regulation and cheap power made it second only to Virginia for data centres. The trigger is a staggering queue: ERCOT's interconnection requests doubled from 233GW in January to 474GW, about 90% data centres, more than five times the grid's all-time peak demand. Audits will demand power and water use, noise mitigation, light controls, tax-incentive use, and ownership details - after a voluntary survey that most operators simply ignored.
