Make Safari work your way with fewer extensions. 1Extn brings useful Safari tools, keyword searches, Share actions, scripts, and website redirects together in one focused app. Start with ready-made features, then customize more when you need them. CHOOSE YOUR SAFARI TOOL Use 1Extn - Tools for the job you need. Read pages more comfortably, inspect page source, use Picture in Picture, create QR codes, translate pages, build YouTube playlists, find lyrics, or connect Safari to Apple Shortcuts and Scriptable. DO MORE FROM THE SHARE MENU Use 1Extn Actions to: • Copy a page title and clean link • Search the current page • Find selected text or a page title on YouTube • Summarize a page • Open a saved website Choose which actions appear and arrange them around the way you browse. SEARCH FROM SAFARI’S ADDRESS BAR Create your own keyword search engines for websites you use often. Type a short keyword followed by your search into Safari’s address bar, and 1Extn sends it to the search engine you selected. AUTOMATE YOUR BROWSING Save scripts that run when you choose them or automatically on matching pages. Ready-made scripts offer an easy starting point, while advanced users can add their own code or script URLs. Create redirects to send matching website links somewhere else automatically. Redirects can preserve the rest of the page address and optionally include subdomains or both HTTP and HTTPS links. SIMPLE TO START, FLEXIBLE WHEN NEEDED A guided setup explains which extensions to enable and lets you choose your first Safari tool. Extras keeps scripts, searches, redirects, Share actions, Shortcuts, and Scriptable settings in one place. 1Extn’s ready-made features require no coding. For users who want more control, custom scripts, Apple Shortcuts, Scriptable workflows, backups, and sharing are available too. Safari extensions must be enabled in Settings. Some tools open third-party apps or websites and depend on those services being installed or available.
