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.

Ray is an open-source CLI tool that plugs into your bank via Plaid, analyzes your actual transactions, and gives you an AI financial advisor that already knows your finances before you ask. Unlike dashboards that show charts, Ray tells you what to do: it surfaces net worth, spending trends, budget status, and upcoming obligations immediately on launch, with proactive recommendations tied to goals you've set. All your data stays local in an AES-256 encrypted SQLite database. PII is stripped before anything reaches the Claude API, meaning your account numbers and names never leave your machine. The app gamifies financial discipline with a 0-100 daily score and achievement unlocks like "Monk Mode" for zero-spend streaks — quirky, but effective for behavior change. Ray is self-hostable with your own Anthropic and Plaid API keys (free), or you can pay $10/month for a managed tier with Stripe integration. Built in TypeScript, it's early-stage but the architecture is unusually thoughtful for an indie finance tool: local-first, encrypted, PII-safe, and genuinely useful rather than just another chart app.
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.”
“Plaid integration means you're still giving OAuth access to your bank accounts to a solo developer's app. The self-hosted path requires Anthropic AND Plaid API keys — that's two paid services before you see a single transaction. Most people will bounce before setup is complete.”
“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.”
“Financial AI that runs locally, doesn't sell your data, and actually advises rather than visualizes is the right model. As agentic AI matures, this pattern — local LLM reasoning on sensitive personal data — will be how we handle everything from health to taxes.”
“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.”
“Local-first, encrypted, open-source, bring-your-own-keys — this is how AI finance tools should be built. The Plaid integration means it actually knows your real numbers instead of asking you to enter transactions manually. For developers comfortable with a terminal, this is an instant ship.”
“The behavioral scoring system with achievement unlocks is genuinely clever — 'Kitchen Hero' for not eating out all week makes budgeting feel more like a game. CLI aesthetics won't win design awards but the product thinking behind it is solid.”
