Umbra - The infinite canvas that replaces your subscription stack.

Existing whiteboards like Miro isolate ideation from actual work. Umbra is a canvas that embeds complete productivity tools directly on one surface. Instead of switching tabs and paying for 5+ SaaS subscriptions, you get real .docx editors, .xlsx spreadsheets, native PDF signing, kanban boards, and presentations. Your files stay on your disk, collaboration is end-to-end encrypted, and an integrated AI bridge lets local agents build boards with you. For students, engineers, planners and more.
