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.

Velo lets you record or upload anything — slides, PDFs, docs, screen recordings, websites — and instantly converts it into a polished video message narrated by a hyper-realistic AI avatar with lip sync, eye blinks, and natural gestures. The whole workflow runs in-browser with no downloads required. The key insight is async communication fatigue: teams are drowning in wall-of-text Slack messages and poorly-produced Loom videos, but nobody has time to polish a proper recording. Velo fills the gap by letting you share a PDF, pick a voice, and ship a professional-looking walkthrough in under two minutes. It launched on Product Hunt today and hit #1 with 464 upvotes — unusually strong traction for a non-developer tool. The avatar quality is notably better than earlier AI presenter tools. Early users are reporting it as a replacement for Loom in cases where they want a "polished" look without showing their face or spending time on editing.
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 in-browser workflow is genuinely frictionless — paste a link, pick a voice, done. This is the kind of async communication tool I'd actually use instead of recording another mediocre Loom.”
“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.”
“AI avatars in 2026 still read as 'uncanny valley corporate' and that's going to cap adoption in informal team settings. Also no pricing transparency at launch is a red flag — freemium often means 'free for 30 seconds of video.'”
“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.”
“Async video is eating synchronous meetings and Velo's approach — no face, no setup, just content — could accelerate that significantly for distributed teams. This is what the next generation of internal communication looks like.”
“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.”
“As a content creator I've been waiting for a tool that makes me look polished without a studio setup. The avatar quality here actually clears my bar — I'd use this for client-facing walkthroughs without hesitation.”
