Everything, in one tab. Now with the people you work with. Peak is a browser with the rest of your work already inside it: notes, task boards, whiteboards, a calendar, time tracking and invoices, mail, PDFs, photos, vector drawing, video, music, slides, websites, your finances and more than twenty tools. On iPhone, iPad and Mac. WORK TOGETHER Share a task board, whiteboard, note, calendar, project, site, drawing, deck or game with anyone who has an Apple ID. Everyone sees every change and can make their own, and Peak shows who changed what. It goes through iCloud, end-to-end encrypted, and over Mesh between devices nearby. No Peak server, no account. YOUR CALENDAR, ALL OF IT Personal, family and team calendars you keep with others, your Social Studio posts, invoices falling due and the hours you worked, beside Apple Calendar, each shown or hidden from one menu. PEAK HOURS Track time against clients and projects with a timer that follows you between devices. Timesheets, absence, budgets and reports. Make clean PDF invoices and email them. Teams hand in weeks and approve time off together. PEAK AI, ON YOUR TERMS Use AI if you want to: on your device, with your own key, or not at all. Peak AI sees the tab in front, works across your notes, boards and calendar, and asks before it changes anything. Ask it from Siri, talk to it out loud in Basecamp, or let it use the tools on your Mac nearby. Your own bots remember, wake up on schedule and work at one table. MAKE THINGS Contour for vector drawing, Darkroom for photos, Folio for PDFs, a full video editor, slides, websites, mind maps on an endless whiteboard, and Social Studio for writing and planning posts for several brands, with pictures and video. NOTES THAT THINK Markdown notes that run Python on your device, with charts, maths and diagrams. Recents and History find anything again. A second brain that is yours. PRIVATE BY DESIGN No account. No tracking. No analytics. Your work stays on your devices and syncs only through your own iCloud.
