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.

TrendRadar (v6.6.1) is an AI-driven public opinion and trend monitoring system that aggregates multi-platform news feeds, RSS sources, and social signals with AI-powered smart filtering, sentiment insights, trend prediction, and multi-channel notifications. It supports WeChat, Telegram, Slack, email, ntfy, and Bark for alerts. The v6.6.0 update added a major new feature: MCP integration that lets AI agents query trend data conversationally without writing any custom integration code. The system uses LiteLLM for unified model support across OpenAI, DeepSeek, Gemini, Claude, and other providers, making it model-agnostic. Recent updates added browser-based HTML reports with dark mode, real-time search within reports, and 30-second Docker deployment. It has accumulated 54,000+ GitHub stars and continues to trend as MCP tooling becomes the standard for AI agent integrations. For competitive intelligence teams, researchers, and developers who need to monitor a domain and surface signal from noise, TrendRadar's combination of broad source aggregation, AI filtering, and now native MCP support makes it a practical daily driver. The MCP integration means it slots directly into agent workflows — an agent can ask "what's trending in quantum computing this week" and get a structured answer from your monitored feeds.

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.

TrendRadar is fundamentally as good as its source configuration — garbage feeds in, garbage trends out. AI 'smart filtering' is still imprecise for niche domains without significant prompt tuning. If you need real competitive intelligence for a B2B vertical, you'll spend considerable time configuring and calibrating sources before getting reliable signal. The out-of-box setup is mostly consumer news feeds.

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.

MCP is rapidly becoming the connective tissue of AI agent stacks, and tools with good MCP interfaces become ambient infrastructure for agents rather than just human-facing dashboards. TrendRadar's MCP bot enables a class of agent workflows — monitor a space, detect a signal, take an action — that previously required bespoke integration work. This is a building block for autonomous research agents.

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.

The MCP integration is the v6.6 unlock that makes TrendRadar genuinely agent-native. Querying curated trend data conversationally without writing integration code is exactly what agentic workflows need. 54k stars says the core monitoring functionality is solid — this is a battle-tested tool that's now been MCP-ified, not a new experiment.

For creators tracking trends across niches to identify content opportunities, TrendRadar's aggregation plus AI filtering is a significant time-saver over manually monitoring dozens of feeds. The HTML reports with dark mode and real-time search make the output actually useful for review, not just a firehose of raw items.
