On a video call only one person can talk at a time, so a remote brainstorm produces a fraction of the ideas an in-person one does. The fix is writing in parallel: everyone adds cards simultaneously, then you talk about what appeared.
Ten minutes of silent card-writing from six people beats an hour of discussion. Nobody waits for a turn and nobody's idea is lost because someone else was mid-sentence.
Participants join from a link with no account and no install, so time-zone stragglers can add cards before the call without any setup.
When the board goes quiet, AI reads what is already there and suggests angles nobody has taken yet, which restarts the group without the facilitator having to supply all the ideas.
Open the board before the meeting and share the link. People in other time zones add cards when they are awake, and the live session focuses on discussing and prioritising what is already on the board.
No. Only the facilitator who creates the board needs an account. Everyone else joins from the link and starts adding cards immediately.
