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.

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
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
