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 goes beyond search to become a proactive on-device agent capable of managing calendars, controlling apps, and providing real-time translation. It competes directly with Google Assistant by taking actions rather than just surfacing answers. The assistant is positioned as an AI-native replacement for the default Android assistant layer.
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.”
“The category is proactive mobile assistant, and the direct competitor is Google Assistant — which Google has been slowly cannibalizing with Gemini while leaving a genuine gap in reliable on-device action-taking. Perplexity's bet is specific: they're wagering that their search quality and model integration is good enough to own the default assistant slot on Android before Google locks it down with Gemini natively. Where this breaks is power users with complex multi-app workflows — the moment you need it to draft a reply, attach a file from Drive, and schedule a follow-up in one shot, current on-device agent reliability falls apart. What kills this in 12 months isn't a competitor — it's Google shipping Gemini as a mandatory default assistant in Android 16 and closing the third-party assistant API surface. To be wrong about that, Google would have to lose an antitrust battle specifically over assistant defaults.”
“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 falsifiable: within 36 months, the OS-level assistant slot becomes the most valuable piece of real estate on mobile, and whoever owns it owns the user's intent graph. Perplexity is betting that the assistant layer decouples from the OS manufacturer before Google can re-couple it with Gemini — a real race with a real dependency on regulatory pressure and Android's openness persisting. The second-order effect nobody is talking about: if Perplexity's assistant accumulates enough behavioral data from proactive actions — calendar patterns, app usage, translation contexts — they build a personalization moat that their search product has never had. The trend line is the shift from reactive query-response to ambient intent capture; Perplexity is on-time, not early, but they're one of the only non-platform players with the model quality to make it credible.”
“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 buyer here is the consumer who decides to swap their default assistant — a notoriously hard conversion that historically requires either zero friction or a viral forcing function, and this has neither. The pricing architecture is a problem: free tier commoditizes the product against Google's free default, and $20/mo Pro is a hard sell when the incumbent costs nothing and is already on the device. The moat question is the real issue — Perplexity's defensibility in search was always distribution, not model quality, and on Android they're fighting for distribution against the platform owner. When Google ships proactive Gemini actions as a system-level feature in a quarterly Android update, Perplexity's action layer becomes a third-party workaround. What would need to change: a carrier or OEM distribution deal that makes Perplexity the default out of the box, which is exactly the kind of deal Google's agreements with OEMs historically prevent.”
“The job-to-be-done is clear and single-threaded: be the assistant that both answers and acts without making you switch apps. That's a real job, and current Google Assistant does it poorly enough that there's genuine hire-me potential here. The onboarding concern is real — setting a third-party app as the default assistant on Android requires navigating Settings sub-menus that most users abandon before completing, which means Perplexity has to earn the switch before they can deliver value, a sequence that's backwards from good onboarding. The product opinion is there: Perplexity has bet on proactive and ambient over reactive and query-based, which is a genuine point of view. The gap between what's shipped and what's needed is reliable multi-step action completion — one failed calendar creation or misread translation and users revert to the default, and that trust window is narrow.”
