MindMup

web-based MindMapping app - kinda similar to FreeMind, imports/exports FreeMind, has quick-keys so it's faster to make outline-type-notes than something like Miro. https://www.mindmup.com/

Free version depends on GoogleDrive for storage. Personal Gold is $25/yr, Team Gold is $50/yr for 10 users. https://www.mindmup.com/mindmup-gold/index.html
