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.

Caret brings system-wide AI autocomplete to macOS with a single keystroke: Tab. Unlike tools that require you to open a specific app or switch contexts, Caret operates at the OS input layer — any text field, any application, anywhere on your Mac. It reads the surrounding text for context and offers completions inline, with zero UI chrome. The implementation uses macOS Accessibility APIs to hook into the text input stack across all applications. Context is gathered from the active window's text content, and completions are generated via a cloud LLM (with local model support on the roadmap). There's no menu bar app cluttering your workflow — just Tab when you want help, nothing when you don't. The simplicity is the product. While Raycast, Copilot, and similar tools add layers of UI, Caret bets that the right abstraction is "Tab, everywhere." For high-volume writers, support staff, and developers who live in diverse tools all day, this is the kind of ambient AI that actually reduces friction rather than adding it.
Reviewer scorecard
“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.”
“Hooking into the macOS Accessibility layer for universal autocomplete is exactly the right architecture — no app-specific plugins, no context-switching. If the latency is under 200ms this is an instant productivity multiplier for anyone who types for a living.”
“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.”
“Accessibility API access is a significant permission to grant any app — this tool can see everything you type in every application. Until there's a clear privacy audit and local model option, the security surface is hard to accept for professional use.”
“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.”
“System-level AI input layers are the next frontier after app-level AI. Caret is the first credible Mac implementation — expect Apple to build this natively into macOS within 18 months, validating the concept while commoditizing this specific product.”
“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.”
“As someone who writes across Notion, Figma, email, and Slack simultaneously, a context-aware Tab that works everywhere is the dream. No mode-switching, no copy-paste to an AI chat window — just inline continuation of your own voice.”
