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 AI-native browser from Perplexity AI that embeds agentic search and task automation directly into the browsing experience. It can autonomously fill forms, book appointments, and summarize web pages on command without switching to a separate AI interface. The browser positions itself as the first product where the AI layer is the browser itself, not a sidebar or extension bolted onto Chrome.
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 competitors here are Arc Browser's AI features, Dia from The Browser Company, Google's built-in Gemini integration in Chrome, and frankly just using Perplexity in a tab. The scenario where Comet breaks is the moment a user hits a site with aggressive bot detection, a multi-step OAuth flow, or a form that requires human verification — and that's the majority of 'book an appointment' use cases in the real world. My prediction for what kills this in 12 months: Google ships Gemini-native task execution in Chrome and the 3.5 billion people who already have Chrome installed don't download a new browser for a feature they get for free. For Comet to earn a ship, it needs to demonstrate autonomous task completion on a real-world benchmark — not a curated demo set — and show completion rates above 70% on genuinely complex multi-step workflows.”
“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 Comet is betting on: within three years, the browser's primary job shifts from rendering documents to executing intentions, and whoever owns the execution layer owns the session data that trains the next generation of personal agents. The dependency that has to hold is that users will switch browsers — which historically requires extraordinary activation energy, but smartphone-generation users have shown less browser loyalty than desktop users, and Perplexity already has distribution through its search product. The second-order effect that matters most isn't the time saved booking appointments; it's that Comet positions Perplexity to capture behavioral clickstream data at a scale that currently only Google holds, which becomes the actual moat. This is riding the trend of 'intent graph beats knowledge graph' and Perplexity is approximately on-time — not early enough to be alone, but not late enough to be irrelevant.”
“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 the existing Perplexity Pro subscriber who is already paying $20/month and now gets a reason to make Perplexity their primary browsing context, not just a search tab — that's a defensible expansion play into a relationship they already own. The moat question is harder: browser switching costs are real but the moat isn't the browser itself, it's the behavioral data and the agent memory that accumulates over sessions, which is the right answer but requires years of retention to materialize. The stress-test that concerns me most isn't Google — it's that Perplexity's own unit economics depend on query costs, and an agentic browser that runs multi-step tasks is dramatically more expensive per session than a search query; if they can't make the margin work at scale, the Pro pricing doesn't hold.”
“The job-to-be-done as stated is 'browse the web and get things done without context-switching to an AI tool' — which is one coherent job, so the focus is there. The problem is completeness: a browser only works as a daily driver if it handles 100% of browsing tasks, and Comet launching without extension support, established sync infrastructure, password manager integration, and a mature dev tools panel means users will dual-wield Chrome and Comet for months, which is the death state for browser adoption. The product has a clear opinion — AI executes, human approves — but the onboarding question I need answered is whether a new user reaches a successful autonomous task completion in under five minutes or spends that time granting permissions and watching it fail on a CAPTCHA.”
