What it does
Allume organizes ideas on nested boards that can hold cards, text, ink, images, videos, PDFs, web links, and other files. Shared workspaces add live cursors, comments, and collaboration. The current site presents a free tier with two workspaces, 100 cards per workspace, and one collaborator; Unlimited is $9.99/month or $99.99/year. A Setapp option is also listed. The product page describes the app on Mac, iPad, and iPhone and notes that it is designed for developing ideas rather than a conventional endless workshop board.
Allume fits people who think by collecting and rearranging ideas rather than writing a linear notebook. Nested boards let a topic grow into sub-boards, while cards, text, ink, files, PDFs, and links keep source material near the developing thought. Shared workspaces support collaborators with cursors and comments. It is best treated as a spatial note system, not a feature-complete workshop whiteboard: the vendor emphasizes nested idea development and does not position it around facilitation tools. The free tier is limited to two workspaces, 100 cards per workspace, and one collaborator; Unlimited is $9.99/month or $99.99/year, with a separate Setapp option.
