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.

VoiceOS is a system-level voice AI layer from WakoAI Inc. (YC X25 batch) that goes beyond dictation into genuine voice-driven automation. The product operates in four modes: Dictation (speech-to-text with automatic cleanup and formatting), Agent (executes real actions across Slack, Gmail, Google Calendar, Notion, Drive, Docs, Sheets, Spotify, and the web), Ask (answers questions about what's currently on screen), and Edit (rewrites selected text via voice commands). The Agent mode is where VoiceOS distinguishes itself from the crowded dictation market. Rather than transcribing and leaving execution to the user, it completes multi-step tasks end-to-end — "Schedule a meeting with the team for next Tuesday and add the Notion doc I have open to the invite" becomes a single voice command. It supports 100+ languages with claimed 98%+ accuracy and is built with enterprise compliance in mind (SOC 2 Type II, ISO 27001). YC backing and a freemium model (100 uses/week free, $12/mo Pro) positions this for both consumer and B2B adoption. The biggest moat question is whether voice interaction actually sticks as a primary modality for knowledge workers, or whether it remains a niche for accessibility and mobility use cases.
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.”
“The screen-aware Ask mode is the sleeper feature here — being able to voice-query what's visible without copy-pasting or switching contexts could meaningfully speed up debugging and code review sessions. SOC 2 compliance out of the gate suggests enterprise ambitions are serious.”
“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.”
“Voice-first productivity has a long history of hype and limited adoption outside accessibility use cases. Open-plan offices and shared spaces make this impractical for most knowledge workers. The 100-use free tier is also quite restrictive for genuine evaluation.”
“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.”
“Operating system-level AI with real action execution across major productivity apps is the interface layer that was supposed to come with Apple Intelligence but didn't. VoiceOS treating the OS as an action surface rather than just a transcription endpoint is architecturally correct.”
“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 Edit mode alone could transform how I work — rewriting captions, adjusting tone on emails, reformatting headings while I'm thinking out loud rather than mousing around. For solo creators working late nights, hands-free feels genuinely natural.”
