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.

Travel Hacking Toolkit is an MCP-based skills layer that teaches AI assistants how to search award flights, compare loyalty program valuations, and surface hotel points deals in natural language. Built by Michael Borohovski and posted as a Show HN, it connects Claude Code and OpenCode to live travel APIs including Seats.aero, SerpAPI, Duffel, and AwardWallet through structured markdown "skills" files that teach the AI how to call each service. The toolkit includes MCP servers for Skiplagged, Kiwi.com, Trivago, Ferryhopper, and Airbnb, enabling queries like "find me a 60,000-mile business class flight to Tokyo and compare it to cash prices." Static data files encode airline alliance structures, hotel chain partner awards, historical sweet spots, and community-sourced valuations—giving the AI grounded knowledge rather than hallucinated redemption values. The project is deliberately low-abstraction: skills are readable markdown files you can edit to add new programs or APIs, and it requires no persistent backend. With 205 stars from a Show HN debut, it's a small but focused tool for the travel hacking community that finally gives the "ask your AI for deals" fantasy some real API teeth.
Reviewer scorecard
“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.”
“Most of these APIs require paid keys or have aggressive rate limits, and the 'sweet spots' data will go stale quickly as airlines devalue programs. This solves a real problem but requires significant manual maintenance to stay useful—you're essentially signing up to maintain your own travel hacking research infrastructure.”
“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.”
“This is an early template for domain-specific MCP skill sets—curated API knowledge plus structured data that turns a general AI assistant into a specialist. As MCP adoption grows, we'll see these skill bundles for every vertical from legal research to healthcare, and travel hacking is a natural first mover.”
“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 architecture is exactly right for this problem—travel APIs are diverse and constantly changing, and skills-as-markdown-files means any developer can add a new loyalty program or airline API in 30 minutes without touching a codebase. The Seats.aero integration alone makes this worth setting up.”
“Finally something that makes the 'just ask your AI to book travel' promise real rather than theoretical. The alliance and partner award data files are the kind of curated, hard-to-find knowledge that normally lives in obscure blog posts—having it structured for AI consumption is genuinely useful.”
