CoAgentor moves AI beyond meeting summaries into active participation: AI agents join your live calls, listen to the conversation, and when they have relevant data or an answer, they raise their hand and speak. Built by Josh Torrey, it launched on Product Hunt today with a free tier. The distinction from tools like Otter.ai or Fireflies is fundamental. Those tools are recorders. CoAgentor is a participant — it surfaces data points, answers factual questions, and can be configured with domain-specific knowledge so it responds as a subject-matter expert in real time. Imagine a sales call where your agent pulls up deal history the moment a client mentions a past project, or an engineering standup where the agent flags a dependency conflict as it's discussed. This sits at the intersection of two fast-moving trends: voice-first AI interfaces (driven by GPT-4o's real-time voice and Gemini Live) and agentic tool use. CoAgentor is an early implementation of what will likely become table stakes in enterprise communication tools — AI participants who contribute rather than just record.

Comet Browser
Perplexity's AI-native browser that browses, fills forms, and acts for you

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.
Reviewer scorecard
“Real-time voice participation in meetings is a genuinely different category than transcription. The use case for a technical agent that flags code issues or pulls up documentation during an engineering discussion is immediately valuable. Free tier makes it worth testing today.”
“An AI that speaks unbidden in meetings is a social nightmare waiting to happen. The latency, false positive rate, and awkward interruptions could tank team trust fast. And who controls when it talks? Until the UX around agent participation is much more refined, this will cause more chaos than value.”
“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.”
“Within three years, having an AI participant in important meetings will be as normal as screen sharing. CoAgentor is one of the first serious attempts to define what that participation looks like. The teams that figure out agent-meeting UX now will have a significant advantage.”
“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.”
“Creative meetings and brainstorms thrive on ambiguity and free association — having an AI interject with data points can kill that energy. The use case feels narrow: structured, information-dense meetings work; creative or sensitive discussions definitely don't.”
“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.”
