Brick Think
Free, open-source platform for running LEGO® SERIOUS PLAY® remotely
...Participants build on breakout-room canvases with live cursors, presence, per-brick reactions, and threaded comments. Rooms auto-compose each member's individual model into one shared view. A library of 20 scenario templates covers every stage, and AI session reports run on the facilitator's own Anthropic key.
Apache 2.0, free forever, no paid tier. It ships original brick assets and uses no LEGO trademark assets.
