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.

Toki 2.0 takes the gap between intention and execution seriously. You type a goal — 'learn piano', 'ship the MVP', 'train for a half marathon' — and Toki converts it into a structured, time-blocked schedule on your actual calendar. The 2.0 update focuses specifically on handling vague inputs: goals without deadlines, interests without clear milestones, and ambitions without a plan. The engine behind it does two things: it breaks goals into concrete sub-tasks with realistic time estimates, and it finds open slots in your existing calendar to place them. It accounts for your current commitments, working hours preferences, and energy patterns based on historical scheduling behavior. The output is a calendar, not a to-do list — each item has a start time and a duration. This is an indie launch from a small team shipping on Product Hunt today. The concept is deceptively simple but the execution gap — converting 'I want to do X' into an actual calendar event with a specific time — is where most people's goals go to die. Toki makes that conversion automatic.
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.”
“Every AI scheduling tool faces the same cold-start problem: the AI doesn't know what your goals actually require, so it guesses. 'Learn piano' could be 15 minutes or 2 hours a day depending on your ambition level. Until AI scheduling has genuine context about your life and real feedback loops, these plans are mostly aspirational fiction dressed as a calendar.”
“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.”
“AI-mediated time allocation is underrated as a category. Most knowledge workers have no systematic way to translate priorities into time. Tools that automate the scheduling layer — freeing humans to focus on defining what matters — are going to become standard productivity infrastructure within three years.”
“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 calendar integration is what separates this from every other goal-setting app. Putting it on the calendar is the commitment. If this handles Google Calendar and Outlook reliably, it solves a real friction point. The 2.0 focus on vague inputs is the right problem to solve — structured goal input was always fake precision.”
“As someone who juggles creative projects alongside client work, the idea-to-calendar conversion solves a real problem. The question is whether it handles irregular schedules and creative flow states intelligently. If it just force-fits rigid blocks, it'll feel clinical. But the impulse is exactly right — intentions without time don't become reality.”
