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.

Seven AI models debate and converge on your best open source idea

Project Parliament is a FastAPI + vanilla JS web app that runs a structured 7-step deliberation workflow to help developers find open-source project ideas matching their skills and goals. Multiple AI models (via OpenRouter: GPT, Gemini, Claude, Grok, Qwen) independently propose ideas, then specialized agents critique market viability, assess builder fit, evaluate open-source sustainability, and synthesize a final recommendation with a backup. A 'Performance Review' step scores each model's contribution. Input your background and constraints; get back a grounded project proposal with actionable first steps. Session history stored locally in JSON.
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.”
“Parliament suffers from the fundamental problem of all AI ideation tools: the models converge on plausible-sounding but generic ideas that have been tried a hundred times. 'A CLI for X' or 'a SaaS wrapper around Y' will dominate every output regardless of your unique background. Self-knowledge and market research beat any multi-model pipeline for finding good ideas.”
“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.”
“The 'parliament' pattern — expand, consolidate, debate, converge — is a generalizable workflow architecture, not just for project ideas. Watch for this deliberation structure to appear in legal research, medical diagnosis, and policy analysis tools. This indie project is a clear proof-of-concept for how multi-model systems should be structured.”
“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 seven-step structure is the product here, not the code. Having a dedicated 'Market Skeptic' and 'Builder Fit Judge' agent in the pipeline catches the two most common ways indie projects fail before you start. The model performance scoring is a clever meta-feature that actually helps you pick the right model for each step going forward.”
“As someone who gets paralyzed by too many project ideas, having an opinionated pipeline force a winner is genuinely useful. The 'primary + backup recommendation with actionable steps' output format is well-designed for actually starting something. Setup requires your own API keys which is a friction point, but the local-first approach means your ideas stay private.”
