Glean's Agents Platform is a generally available enterprise AI agent builder that lets teams create AI agents with secure, permissioned access to company knowledge indexed across 100+ business apps. Agents can trigger workflows, answer questions grounded in internal data, and integrate with tools like Salesforce, Jira, and ServiceNow. It's built on top of Glean's existing enterprise search infrastructure, making the knowledge layer the core differentiator.

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
“The direct competitors here are ServiceNow's Now Assist, Microsoft Copilot Studio, and Salesforce Agentforce — all of which have massive distribution advantages. Where Glean actually earns its place is the knowledge layer: if you've already got Glean indexing your company's internal content with real permissions, building agents on top of that foundation is meaningfully different from a blank-slate agent builder. The scenario where this breaks is large enterprises with fragmented IT budgets, where Glean has to compete against the existing Microsoft 365 or ServiceNow contract rather than supplement it. What kills this in 12 months isn't a competitor — it's Microsoft bundling Copilot Studio capabilities deeper into M365 E5 licenses and making the 'we already have Glean' argument harder to close.”
“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.”
“The buyer here is the CIO or VP of IT, pulling from digital transformation or enterprise AI budget — not a departmental line item. Glean's smart move is that the Agents Platform is an expansion motion inside an existing Glean contract, not a net-new sale, which is the only land-and-expand story that actually works. The moat is real but narrow: it's the indexed, permissioned knowledge graph that takes months to build and tune per enterprise, creating genuine switching costs. The stress test is whether enterprises will consolidate on one platform player — if Microsoft or Salesforce offers 80% of this functionality bundled into existing spend, Glean's standalone value proposition compresses fast unless they keep the knowledge indexing quality visibly ahead.”
“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 primitive here is a hosted agent runtime that uses Glean's search index as a retrieval layer and exposes workflow triggers — essentially a RAG-grounded agent builder with pre-built connectors. The DX bet is that enterprises want a no-code/low-code surface rather than composable APIs they can wire into their own stack, which is probably the right call for the buyer but makes this nearly useless if you want to integrate it into an existing internal toolchain. The moment of truth — can a developer get an agent running against real company data in under 30 minutes — is entirely gated behind the sales cycle and enterprise provisioning, which means there's no public hello-world to evaluate. The blog post has no repo, no public API docs, no sandbox, and no pricing: three red flags for any tool claiming to serve builders.”
“The job-to-be-done is precise: 'help enterprise employees get answers and trigger actions using company knowledge without requiring IT to build custom integrations from scratch.' That's a real, well-scoped problem. The completeness question is where Glean has an edge over blank-slate agent builders — because the knowledge indexing is already done for existing Glean customers, the activation cost for the first useful agent should be low compared to starting from Copilot Studio with an empty SharePoint. The gap I'd flag is that 'over 100 business apps' is a connector count, not a measure of integration depth — the real test is whether an agent can reliably take action in Salesforce or ServiceNow, not just read from them, and nothing in the GA announcement quantifies that reliability at scale.”
“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.”
“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.”
