Glean Agentic Actions extends the enterprise AI search platform to execute multi-step actions across connected SaaS tools like Salesforce, Jira, and Slack—not just retrieve information. Users can trigger workflows through natural language while an approval layer governs sensitive operations. It builds on Glean's existing enterprise connectivity and permissions model.

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 primitive here is an enterprise-permissioned action layer sitting on top of pre-built SaaS connectors — and that's actually non-trivial to build. The DX bet is that enterprises get value without writing glue code, which is the right call for this buyer. The approval workflow for sensitive ops is the specific technical decision that earns a ship: it's the thing that makes an IT admin actually allow agents to write to Salesforce instead of just read from it. What I want to see is a proper API surface so platform teams can register custom actions without waiting on Glean's connector roadmap — without that, you're locked into whatever integrations they've shipped.”
“Direct competitors are Moveworks and ServiceNow's Now Assist, and both have been doing agentic actions in enterprise for longer. Glean's advantage is that its search index is already the connective tissue for many large orgs, so adding action execution is a natural extension rather than a cold-start problem — that's a real differentiator, not marketing. The scenario where this breaks is multi-step actions across three or more systems where context needs to persist mid-chain; every enterprise agent tool I've seen collapse on that specific workflow. What kills this in 12 months: Salesforce and Atlassian ship native cross-tool agents to their existing enterprise customers and Glean's connector advantage evaporates overnight.”
“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, and the budget is enterprise productivity or digital transformation — this is not a bottom-up PLG play, which is fine because Glean has never pretended it was. The moat is real and compounding: Glean already owns the permissions model and the search index across these enterprises, so adding action execution doesn't require re-selling the security and compliance story from scratch — that's genuine switching cost. The risk is that Glean's connector library has to keep pace with enterprise SaaS sprawl, and the moment a competitor ships better Workday or SAP coverage, the expansion story stalls. The specific business decision that makes this viable is building actions on top of an existing trust relationship rather than asking enterprises to grant write permissions to a new vendor.”
“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 clear and single-threaded: let an employee complete a cross-system work task through one conversational interface instead of tabbing across five SaaS tools. The approval workflow layer is the product opinion that earns this a ship — it signals the team understands that 'autonomous agent' without human checkpoints is a non-starter for enterprise buyers, and they've built the right escape valve. The completeness gap is real though: if your workflow touches a SaaS tool Glean doesn't have a connector for yet, you're still dual-wielding, which means adoption will stall at the edges of the connector catalog. The product needs a clear public roadmap for connector coverage before I'd call this complete.”
“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.”
