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.

omi is an open-source AI platform from BasedHardware that runs continuously on your desktop and mobile devices, capturing screen activity, audio from meetings, and conversations in real time. It synthesizes everything into a persistent memory graph — you can later ask it what was decided in a meeting last Tuesday, what was on-screen during a debug session, or what a colleague said during a standup call. The platform spans macOS, iOS, Android, and even open-hardware wearable devices. The new v0.11.333 release (shipped April 18) adds significantly improved background processing, better MCP integration for feeding memories into coding agents, and a faster ChromaDB-backed retrieval layer. It claimed 824 new GitHub stars in a single day, the highest star velocity on GitHub trending this week. With 300,000+ active users and 10,000+ total stars, omi has quietly become the most widely deployed "always-on" memory layer for AI workflows. Its open hardware companion (a small wearable device) positions it beyond software into ambient computing.
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.”
“MCP integration is the killer feature here — being able to feed real-time meeting context directly into your Claude Code session without copy-pasting is something I've wanted for two years. The 824 stars in one day tells you this resonated with real developers immediately.”
“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.”
“Continuously capturing your screen and all audio is a massive privacy surface. Most workplaces explicitly prohibit recording meetings without consent, and storing that data locally doesn't make the capture part legal. Proceed with caution and check your employment contract.”
“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.”
“This is what a true second brain looks like — not a note-taking app, but a persistent ambient layer that captures life as it happens. The open-hardware wearables angle is early but points to a world where your AI context travels with your body, not just your laptop.”
“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.”
“For content creators who reference past work, client calls, and visual research constantly, having an AI that already has all that context without being explicitly fed it is genuinely transformative. Auto-generating meeting summaries and action items alone saves hours per week.”
