The notch on a MacBook is strange real estate. It is always there. It sits at the top of the screen, close to the menu bar, close to system controls, close to whatever you are doing. But most of the time it is treated like a cutout to design around instead of a place software can use. That felt like a missed opportunity. So I built SwiftNotch , a macOS menu bar app that turns the notch area into an expandable productivity dashboard. Hover near the notch or press Option + Space , and the quiet black shape becomes a small command center for widgets, files, media, shortcuts, developer tools, and window actions. Website: swiftnotch.xyz Demo video: Launch note: SwiftNotch 1.x is free during beta . I want early Mac users to try the full experience, share feedback, and help shape the app before SwiftNotch 2.0 introduces paid plans. The idea I did not want to build another large dashboard that asks you to leave your current app. The goal was the opposite: make useful tools available in the smallest possible space, without breaking flow. The notch is perfect for this because it already behaves like a visual anchor. You know where it is without thinking. If it can expand only when needed, it becomes a temporary interface layer instead of another permanent panel. SwiftNotch starts collapsed. When activated, it opens into a compact dashboard with the widgets and actions you choose. What SwiftNotch does The current app includes 31 built-in widgets across productivity, system utilities, media, automation, and developer workflows. Some examples: Media Control for Spotify, Apple Music, VLC, YouTube, and browser players Shelf for drag-and-drop file staging, quick sharing, paths, iCloud actions, and zip workflows Clipboard History for snippets, links, and quick paste Calendar Events , Reminders , Notes , Weather , World Clock , and Pomodoro Quick Toggles for Wi-Fi, Bluetooth, Dark Mode, and volume Window Snapping with layouts for halves, thirds, quarters, and custom grids Developer H

Hey HN, Henry & Roman here from Cactus. A small, on-device model is fast and private, but sometimes wrong, but frontier models are getting expensive pretty fast. So, we post-trained Gemma 4 E2B post-trained to know when it's wrong. Every response comes with a confidence score between 0 and 1. Developers can accept the on-device when it's high, hand off to a bigger cloud model when it's low. By routing only 15-35% of queries to Gemini 3.1 Flash-Lite, Gemma-4-E2B matches Gemini 3.1 Flash-Lite on m
