Microsoft Copilot Studio now supports autonomous multi-step agent flows that can execute complex business processes end-to-end without constant human intervention. Configurable approval checkpoints let organizations pause execution and require human sign-off before sensitive or high-stakes steps proceed. The update is rolling out to all enterprise tenants, making AI-driven process automation a first-class feature of the Microsoft 365 ecosystem.

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.
Reviewer scorecard
“Approval gating is the missing piece that makes agentic automation actually deployable in enterprise environments — no sane IT team would ship fully autonomous flows without it. The low-code interface means you don't need to babysit every integration, and hooking into existing Power Automate connectors is a massive time saver. My only gripe is that debugging a failed mid-flow agent step is still too opaque.”
“Microsoft is slapping the word 'autonomous' on what is essentially a glorified Power Automate flow with a chatbot skin — the approval gating is good, but let's not pretend this is AGI for your procurement department. Pricing is buried in enterprise licensing labyrinths, and you'll spend more time negotiating your tenant config than actually building agents. Come back when the observability and error-handling story matures.”
“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.”
“Human-in-the-loop approval gating isn't just a safety feature — it's the trust scaffolding that will get boardrooms to actually greenlight agentic AI at scale, and Microsoft is smart to ship it now. This positions Copilot Studio as the enterprise on-ramp for the agentic era, directly competing with Salesforce Agentforce and ServiceNow's AI workflows. The org that figures out which checkpoints to automate away next year will have a serious competitive edge.”
“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.”
“If your work lives in Word docs and Figma files, this update is basically invisible to you — it's laser-focused on back-office process automation rather than anything creative. The Studio UI is cleaner than it used to be, but it still feels like a flowchart tool that got possessed by a language model. Creatives should wait for Microsoft to bring these agent capabilities into Designer or Loop before getting excited.”
“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.”
