Within a 14-day window in March 2026, three companies unveiled always-on AI desktop agents: Perplexity's Comet PC (March 11), Microsoft's Windows Copilot Agent (March 18), and Google's Project Jarvis on Chrome OS (March 23). The timing isn't coincidence — all three are racing to own the layer between users and their local files before one player locks it in.
AI desktop agents are fundamentally different from chatbots: they run continuously, can see your screen, read local files, and take actions across apps — without you asking. The privacy and productivity implications are significant.
The Three Launches Compared
| Product | Company | Launch Date | Platform | Key Feature |
|---|---|---|---|---|
| Comet PC | Perplexity | March 11, 2026 | Mac Mini hardware | Always-on local file awareness, offline AI |
| Windows Copilot Agent | Microsoft | March 18, 2026 | Windows 11 | Cross-app task orchestration via Copilot+ |
| Project Jarvis | March 23, 2026 | Chrome OS / Chromebook | Browser-native agent with Gemini 2.0 |
What "Always-On" Actually Means
Unlike ChatGPT or Gemini where you open a tab and type a query, desktop agents run as background processes. Perplexity's Comet can read your filesystem, notice you're working on a quarterly report, and proactively pull relevant emails and documents into context. Microsoft's agent can watch you draft an email in Outlook and suggest a meeting slot from your calendar without you asking.
The practical benefit is significant time saving on context-switching tasks. The privacy concern is equally significant: an always-on AI that reads local files and monitors screen activity represents a fundamentally different data relationship than a chatbot you query. Perplexity has stated that Comet's AI processing runs locally for sensitive operations, while Google and Microsoft route agent context to cloud models.
What This Means for Indian Users and Enterprises
For Indian IT professionals, Microsoft's Windows Copilot Agent is likely to be the first available option — most enterprise Windows deployments will receive it via Copilot+ PC updates. Google's Jarvis is relevant for the growing Chromebook user base in Indian schools and mid-market enterprises. Perplexity's Comet requires dedicated hardware (Mac Mini-based) and is priced for the US market at launch.
Indian data localisation regulations (under the DPDP Act, 2023) create a compliance question for cloud-routed agents. Enterprises deploying these tools will need to verify whether agent telemetry and context data is processed on Indian servers or routed abroad.
The Bigger Picture
The race to own the desktop AI layer is the next frontier after the chatbot wars. Whoever builds the most useful always-on agent will capture the most valuable real estate in computing: the space between you and your files. Microsoft has the enterprise install base advantage. Google has the data and model quality edge. Perplexity is betting on hardware independence. All three launch windows look conservative — this market will look very different by late 2026.
Frequently Asked Questions
Are these desktop agents available in India?
Microsoft's Windows Copilot Agent is rolling out globally via Windows Update for Copilot+ PCs. Google's Jarvis is in limited preview. Perplexity's Comet PC is US-only at launch with international availability unconfirmed.
Do these agents require an internet connection?
Perplexity's Comet processes sensitive operations locally but requires internet for search. Microsoft and Google's agents are primarily cloud-routed, requiring internet connectivity for most functions.
What's the difference between a desktop agent and a browser extension?
Desktop agents run at the OS level and can access files, applications, and system state across the entire machine. Browser extensions are sandboxed inside the browser and cannot access local files or non-browser apps without explicit OS-level permissions.
