Comet is a desktop browser built by Perplexity AI that deeply integrates its agentic search engine, allowing it to autonomously execute multi-step web tasks on behalf of users. Rather than just surfacing answers, Comet can navigate sites, fill forms, and complete workflows without manual intervention. Early access is gated behind Perplexity Pro with a public waitlist open.

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 category is agentic browser automation — direct competitors are Anthropic's Computer Use, OpenAI Operator, and Arc's now-shelved Browse for Me, all of which have demonstrated the same core loop and hit the same walls: form auth, CAPTCHAs, and any site that detects non-human behavior. Comet breaks the moment a user wants it to handle a logged-in, dynamic SPA that rate-limits bots — which is most of the web that matters. What kills this in 12 months: OpenAI ships Operator to all ChatGPT users for free and Perplexity's differentiation collapses to brand preference. To earn a ship, Comet needs to demonstrate persistent session handling and a credible story for the 60% of high-value tasks that live behind auth walls.

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.

Futurist

The thesis here is specific and falsifiable: by 2027, the browser tab is no longer a viewport you stare at — it's a task queue you delegate to. Comet is betting that the interface layer between humans and the web collapses from 'navigate and click' to 'state intent and verify result.' That's a real trajectory, and Perplexity is one of the few players with a live search index plus the intent-capture surface to make the delegation model feel natural rather than scripted. The second-order effect that matters: if Comet works, SEO as a discipline dies faster than anyone is modeling — the bot reads the page so the human doesn't, and click-through becomes irrelevant. The dependency that has to hold: users must be willing to hand over ambient browsing context to Perplexity's servers, which is a trust bet that sits on regulatory quicksand. Still, as a positioned bet on the trend of intent-first computing, this is early and credible rather than late and derivative.

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 is a Perplexity Pro subscriber who already pays $20/month — Comet is a retention and upgrade mechanism dressed as a product launch, which is actually smart distribution. The moat question is harder: browser distribution is a graveyard (ask Opera, Brave, Arc) and the switching cost of a browser is enormous for consumers but thin for Perplexity because users won't abandon Chrome for search features alone. The business survives model cost compression because Perplexity's value isn't the underlying LLM — it's the index and the task orchestration layer sitting on top of it. What worries me is the expand story: once you've automated the tasks a Pro user cares about, what's the upsell? There's no obvious enterprise tier with audit logs and admin controls mentioned at launch, which means the revenue ceiling is whatever the Pro subscriber count is. Viable, but not yet a standalone business thesis.

The job-to-be-done as stated is 'complete multi-step web tasks autonomously' — that sentence contains an 'and' hiding inside 'multi-step,' which means this product is trying to solve task delegation, context retention, and web navigation simultaneously before nailing any one of them. The onboarding reality: users join a waitlist, get access inside a Pro subscription, and then face the blank-slate problem of not knowing which tasks are reliably automatable versus which will silently fail halfway through. That's not a 2-minute path to value — that's a discovery tax. The product isn't complete enough to replace any existing workflow today because there's no task library, no failure transparency, and no way to audit what the agent actually did. Until Comet ships a defined set of tasks it handles end-to-end with high reliability and surfaces that clearly at onboarding, it's a demo with a waitlist, not a product.

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.
