FigJam suits teams that need a shared space for workshops, planning, and decision-making, including people without prior design-tool experience. It also accommodates short-term contributors from other teams or companies through open sessions.
NoteBookCast can suit teachers, sketchers, and groups who want a shared browser-based board. It may also fit people who prefer to start without registration or save boards through a free account.
