Google's AI Edge Gallery is a mobile application that turns your Android or iPhone into a local LLM inference machine. Available on Android 12+ and iOS 17+, the app runs open-source models—with particular focus on Google's Gemma 4 family—entirely on-device. No internet required, no data leaves your phone, no API costs. The Gallery supports multi-turn conversation with a Thinking Mode that lets you watch the model's reasoning steps, image analysis through multimodal capabilities, voice transcription and translation, model performance benchmarking on your specific device hardware, and even device automation powered by fine-tuned models. Custom models can be loaded via Hugging Face integration. The updated version with official Gemma 4 support is particularly timely: Gemma 4's 2B parameter model has been benchmarked outperforming its 12B predecessor on multi-turn benchmarks, and running it on a modern iPhone or Android flagship is now genuinely fast. For privacy-conscious users, developers who want to test local inference without cloud costs, or anyone who needs AI capabilities in environments without reliable internet, AI Edge Gallery bridges the gap between cutting-edge open-source models and practical mobile use.

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.

On-device LLM inference on consumer phones with Gemma 4 support is a genuine capability milestone. The model benchmarking feature is practically useful for understanding what's actually running where. This is solid infrastructure for mobile AI development testing.

On-device LLM quality still trails cloud APIs significantly for complex tasks. You're trading capability for privacy and offline access—that's a real tradeoff, not a free lunch. Battery drain and thermal throttling on extended sessions remain practical problems on most phones.

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.

Futurist

Local inference on mobile phones is the long game—as models compress and chips improve, the gap between on-device and cloud closes. AI Edge Gallery is Google planting a flag in the world where your phone is your private AI, not a terminal that routes everything through a data center.

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.

Privacy-first, works offline, no subscription—AI Edge Gallery is genuinely useful for creators who travel or work in low-connectivity environments and want AI assistance without sending their work to the cloud. The voice transcription feature alone is worth downloading for on-the-go note capture.

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.
