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.

Perplexity Assistant for Android is a general-availability AI assistant that combines web-grounded search answers with on-device actions like setting reminders, sending messages, and controlling apps. It supports persistent context across multiple sessions, making follow-up queries feel continuous rather than one-shot. It positions itself as a direct replacement for Google Assistant and Samsung Bixby on Android devices.
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.”
“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.”
“This is the first assistant play that actually has a coherent wedge: Perplexity's web-grounded answers are genuinely better than Google Assistant's stale knowledge base, and on-device actions close the gap that made Perplexity a tab-switcher instead of a daily driver. The scenario where this breaks is anything requiring deep calendar management, smart home ecosystems, or third-party app integrations beyond the basics — that's still a Siri/Google Assistant moat that takes years to erode. Prediction: Google ships a meaningfully better Gemini Assistant integration within 18 months and recaptures the Android default, but Perplexity survives as the power-user choice because their search quality creates real loyalty among people who've already switched.”
“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.”
“The thesis here is that the phone assistant layer — long ceded to Google and Apple as untouchable defaults — becomes genuinely contestable once LLM answer quality exceeds the default assistant's by a wide enough margin that users tolerate the friction of switching. Perplexity is betting that web-grounded, citation-backed answers compound into a behavior change where people stop typing into search bars entirely and start talking to a context-aware agent that remembers the last three conversations. The second-order effect that matters: if persistent cross-session context actually works at scale, Perplexity becomes the place where intent accumulates — a dataset about what people are trying to do day-to-day that no search index currently captures. The dependency that has to hold is that Google doesn't flip Gemini Live into a true default on Pixel and Samsung devices before Perplexity builds enough habit; that clock is running, and Perplexity is on-time but not early to this trend.”
“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 job-to-be-done is clear and singular: replace the default Android assistant for people who find Google Assistant too shallow and Gemini too incomplete. Onboarding lives or dies on whether setting Perplexity as the default assistant is a three-tap flow or a settings-archaeology expedition — if it's the latter, the vast majority of potential users bounce before they ever see the value. The product earns its ship on persistent follow-up context, which is the one feature that actually changes behavior rather than just competing on answer quality; 'remember what we talked about last Tuesday' is the unlock that makes this an assistant rather than a fancier search box. The gap is third-party app depth — until 'order me an Uber to where I'm going on Friday' works end-to-end, power users will keep the old assistant as a backup, and dual-wielding is a skip signal.”
“The buyer here is a consumer on the free tier who converts to $20/month Pro, which means Perplexity is running a consumer subscription business on Android where Google controls the default assistant setting, the app store, and the OS update cycle — that's three choke points owned by the primary competitor. The moat question is brutal: Perplexity's answer quality is real, but Google can close that gap faster than Perplexity can build the integration depth that makes switching costs sticky. When Gemini's on-device actions reach parity in 12-18 months, the 'better answers' differential shrinks, and Perplexity is left competing on brand loyalty with a company that has a trillion-dollar distribution advantage. This earns a skip not because the product is bad, but because the unit economics of converting free Android users to $20/month subscribers against a free and pre-installed competitor is a math problem that doesn't work at scale without an enterprise or B2B story that isn't visible yet.”
