Comet is an AI-native desktop browser from Perplexity AI that autonomously executes multi-step web tasks including booking, research, and form filling without manual navigation. It integrates Perplexity's search and reasoning capabilities directly into the browsing layer, enabling goal-directed automation across arbitrary websites. Currently invite-only for Pro subscribers, with broader availability planned for Q3 2026.

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.
Reviewer scorecard
“Comet is competing directly with Arc's Browse, Google's Project Jarvis, and Anthropic's computer-use demos — except those shipped broadly and Comet is invite-only for a Q3 2026 general rollout. The specific failure scenario is obvious: any task requiring login state management, CAPTCHAs, or multi-domain auth handoffs falls apart immediately, and Perplexity hasn't shown evidence of solving those problems at scale. My prediction for what kills this in 12 months: Google ships Gemini-native browser automation in Chrome, erasing Comet's differentiation with zero distribution disadvantage. To earn a ship, Comet needs to demo booking a multi-leg international flight with seat selection, payment, and confirmation — live, unscripted, first try.”
“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 and specific: by 2028, the browser is not a viewport but an execution environment, and the team that controls the AI-browser layer controls the intent graph of the web. Comet is betting on this at the infrastructure level — not bolting agents onto a tab, but rebuilding the browser around the agent primitive. The second-order effect that matters most is what this does to web analytics and SEO: if agents complete tasks without humans seeing pages, the entire attention economy built on pageviews collapses. Comet is riding the computer-use trend line and is roughly on time — OpenAI Operator launched earlier, but browser-native execution versus API-layer automation is a real architectural distinction worth watching. The dependency that has to hold: agentic task completion rates must cross ~85% reliability before mainstream users tolerate it.”
“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 the $20/mo Perplexity Pro subscriber, which means Comet is a retention feature masquerading as a product launch — there's no incremental revenue attached to it unless Perplexity spins it into a higher tier. The moat question is brutal: Comet's agentic capability sits on top of browser automation infrastructure that Google, Microsoft, and OpenAI are all building simultaneously, and none of them need to charge $20/mo to distribute it. The specific business problem is that Perplexity is spending engineering capital on a browser at exactly the moment when its search revenue model remains unproven — this is a distraction bet that only makes sense if it dramatically increases Pro retention or unlocks enterprise contracts. What would need to change: a dedicated Comet tier at $40-50/mo with verifiable task-completion SLAs and an enterprise sales motion.”
“The job-to-be-done is sharp: complete a web task I would otherwise do manually across 4-8 browser tabs. That's a real, recurring job with measurable time cost, and Comet is one of the first products to attempt it at the browser layer rather than the script or extension layer. The onboarding concern is real though — invite-only access means the vast majority of Pro subscribers can't evaluate whether this replaces their current workflow, making it impossible to call this a complete product today. The opinion baked into Comet is correct: the browser should understand goals, not just URLs. The gap between what's shipped and what's needed is a public availability date that isn't six months away, and documented task success rates so users can set realistic expectations before switching.”
“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.”
