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.

Offline-first macOS vault for Markdown notes, Git-backed & AI-ready

Tolaria is an open-source desktop app for macOS that turns a folder of Markdown files into a structured, searchable knowledge base. Built with Tauri, React, and Rust, it stores everything as plain text with YAML frontmatter — no proprietary formats, no cloud lock-in. Every vault is a Git repo, so you get full version history with zero extra setup. The app was built by indie developer Luca Rossi to manage his personal vault of 10,000+ notes. It's keyboard-optimized, works completely offline, and is explicitly designed to be AI-agent-friendly — Claude and other assistants can read and write the vault natively. Its "types as lenses, not schemas" philosophy lets you categorize notes flexibly without enforcing rigid structures. With 2,000+ stars just days after its Show HN debut, Tolaria is clearly filling a real gap. It sits between Obsidian (proprietary, plugin-heavy) and bare-metal text files, offering a polished UI with zero subscription and full data ownership under AGPL-3.0.
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.”
“Tauri + React + Git means no Electron bloat and real version control out of the box. The AI-friendly structure is a genuine differentiator — your knowledge base becomes a first-class context source for coding agents. AGPL means you can audit everything.”
“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.”
“macOS-only limits the audience significantly, and 'AGPL for a personal tool' can create headaches if you ever want to build commercial tooling on top. The 2,000-star count is promising but this is still one indie dev's vision — long-term maintenance is unproven.”
“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.”
“As AI agents increasingly need structured local context, plain-Markdown vaults with Git history become the ideal substrate. Tolaria is positioning itself as the human-readable layer that agents can read and write — that's the right bet for 2026.”
“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.”
“Finally a notes app where the design philosophy matches the power-user reality. Keyboard-first, no bloat, and your 10,000 notes don't end up in someone else's cloud. The YAML frontmatter discipline enforces a structure that makes content actually findable.”
