The basics
What is good brainstorming?
Good brainstorming has two phases: going wide (as many ideas as possible, no judging) and then converging (grouping, spotting themes, picking what to try).
A board with sticky notes supports both — scatter ideas fast, then drag them into clusters and name the themes.

Common questions
What is an affinity diagram?
A way to sort many ideas or observations into groups by similarity, then name each group. The template has example themes to get you started.
What is Crazy 8s?
A fast exercise: eight ideas in eight minutes, one per frame — quantity over polish.
Can a group brainstorm on the same board?
Not live — there's no co-editing. For a group, one person can facilitate on a shared screen, or share a link for everyone to build on their own copy.
Is it free?
Yes, free with no sign-up.
