Comet is a standalone AI-native browser from Perplexity AI that embeds agentic search and task automation directly into the browsing experience. It can autonomously fill forms, book appointments, and summarize web pages on command without switching to a separate AI interface. The browser positions itself as the first product where the AI layer is the browser itself, not a sidebar or extension bolted onto Chrome.

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 direct competitors here are Arc Browser's AI features, Dia from The Browser Company, Google's built-in Gemini integration in Chrome, and frankly just using Perplexity in a tab. The scenario where Comet breaks is the moment a user hits a site with aggressive bot detection, a multi-step OAuth flow, or a form that requires human verification — and that's the majority of 'book an appointment' use cases in the real world. My prediction for what kills this in 12 months: Google ships Gemini-native task execution in Chrome and the 3.5 billion people who already have Chrome installed don't download a new browser for a feature they get for free. For Comet to earn a ship, it needs to demonstrate autonomous task completion on a real-world benchmark — not a curated demo set — and show completion rates above 70% on genuinely complex multi-step workflows.”
“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 Comet is betting on: within three years, the browser's primary job shifts from rendering documents to executing intentions, and whoever owns the execution layer owns the session data that trains the next generation of personal agents. The dependency that has to hold is that users will switch browsers — which historically requires extraordinary activation energy, but smartphone-generation users have shown less browser loyalty than desktop users, and Perplexity already has distribution through its search product. The second-order effect that matters most isn't the time saved booking appointments; it's that Comet positions Perplexity to capture behavioral clickstream data at a scale that currently only Google holds, which becomes the actual moat. This is riding the trend of 'intent graph beats knowledge graph' and Perplexity is approximately on-time — not early enough to be alone, but not late enough to be irrelevant.”
“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 here is the existing Perplexity Pro subscriber who is already paying $20/month and now gets a reason to make Perplexity their primary browsing context, not just a search tab — that's a defensible expansion play into a relationship they already own. The moat question is harder: browser switching costs are real but the moat isn't the browser itself, it's the behavioral data and the agent memory that accumulates over sessions, which is the right answer but requires years of retention to materialize. The stress-test that concerns me most isn't Google — it's that Perplexity's own unit economics depend on query costs, and an agentic browser that runs multi-step tasks is dramatically more expensive per session than a search query; if they can't make the margin work at scale, the Pro pricing doesn't hold.”
“The job-to-be-done as stated is 'browse the web and get things done without context-switching to an AI tool' — which is one coherent job, so the focus is there. The problem is completeness: a browser only works as a daily driver if it handles 100% of browsing tasks, and Comet launching without extension support, established sync infrastructure, password manager integration, and a mature dev tools panel means users will dual-wield Chrome and Comet for months, which is the death state for browser adoption. The product has a clear opinion — AI executes, human approves — but the onboarding question I need answered is whether a new user reaches a successful autonomous task completion in under five minutes or spends that time granting permissions and watching it fail on a CAPTCHA.”
“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.”
