Dune is a compact 3-key hardware keypad for Mac that detects which application is in the foreground and automatically remaps its keys to that app's most useful shortcuts — no manual configuration required. Where other macro pads force you to set up profiles and manually switch between them, Dune handles context detection in software and adapts in real time. The device targets developers and power users who constantly hop between tools like VS Code, GitHub, Claude, Zoom, and Slack. Each app gets its own key mappings pre-configured, and the hardware is designed to sit beside the keyboard without disrupting existing muscle memory. The form factor is intentionally minimal: three keys, programmable LEDs for visual feedback on the current context, and plug-and-play USB connectivity. Dune launched today on Product Hunt as the #1 product of the day with over 350 upvotes, reflecting strong indie builder energy. It's positioning itself against the Stream Deck ecosystem but with a much simpler surface area — fewer keys means less configuration paralysis.

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.

The auto-context detection is the whole pitch, and it's a good one. I don't want to manage macro profiles — I want a device that just knows I'm in VS Code and gives me format, run, and debug on three keys. Watching for real-world input lag reviews.

Three keys is a very small surface area to justify a hardware purchase. The Stream Deck Mini has 6 keys for roughly the same price, and its app ecosystem is far more mature. I'd want to see what happens when Dune's context detection misfires in edge cases.

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.

Minimal interfaces with context-aware intelligence are the future of human-computer interaction. Dune is a physical manifestation of the principle that good software should reduce decisions, not multiply them.

74/100 · ship

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.

For creative workflows that hop between Figma, Photoshop, and a browser, this is genuinely appealing. Three programmable keys that auto-adapt beats re-learning which Stream Deck button does what every time I switch contexts.

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.
