Comet is Perplexity's AI-native browser for macOS and Windows that can autonomously navigate the web, fill out forms, and complete multi-step tasks on behalf of users. Rather than adding AI to an existing browser, Comet is built from the ground up with an embedded agent layer that can take action in any website without extensions or plugins. It's currently available in public beta and represents Perplexity's push from search into ambient web automation.

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 here is AI browser agent, and the direct competitors are Arc with Browse, Chrome's built-in Gemini integration, and every Playwright-wrapper startup that launched in 2024. The specific scenario where Comet breaks: any website with a CAPTCHA, a bot-detection layer, or a dynamic login flow — which is most of the websites people actually need agents to navigate. My 12-month kill prediction: Google ships Gemini-native agentic browsing into Chrome for free and Comet's entire distribution thesis evaporates. To earn a ship, Comet needs to demonstrate a reliable task completion rate above 80% on a published, third-party benchmark — not a cherry-picked demo on a frictionless checkout flow.”
“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 3 years, the browser's primary interface is intent-driven rather than URL-driven, and the agent layer sits below the UI rather than on top of it as an extension. That's a falsifiable, specific bet — and it's one I think is roughly on time, not early. The second-order effect that matters here isn't faster form-filling; it's that Perplexity captures the session-level data that Google currently owns through Chrome, which fundamentally shifts who can build the best personal web model. The dependency that has to hold: agent reliability needs to hit a threshold where users trust it with consequential tasks, not just toy demos, and that threshold is further out than Perplexity's beta launch implies.”
“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 unclear in a way that matters: is this a consumer product funded by attention and ads, or a prosumer tool with a subscription model? 'Free beta with pricing TBD' is not a business model, it's a deferral, and for a company that's already raised at a multi-billion valuation, that deferral is a red flag. The moat problem is real — Perplexity's agent layer is only as defensible as its model quality and browser telemetry, and Google can replicate both with Chrome's existing install base. What would need to change: a clear pricing architecture that shows users pay for task completion or saved time, not for a browser they'll abandon the moment Chrome ships the same capability.”
“The job-to-be-done is clean and singular: complete a web task I would otherwise have to do manually. That's a real job, and most tools in this space make users context-switch between a chat interface and a browser, which is exactly the friction Comet eliminates by collapsing them into one surface. The onboarding question I'd need answered before moving this to a strong ship: does a user reach a completed task in their first 2 minutes, or do they spend that time granting permissions and configuring agent scope? The opinion the product needs to have — and may not yet have — is which tasks it's opinionated about doing well versus which it declines, because an agent that attempts everything and fails unpredictably is worse than one that does three things reliably.”
“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.”
